Wildfire Tracker: How to Track Wild Fires Across All 50 States in 2026

A wildfire tracker is a live map that fuses official incident records, mapped fire perimeters, satellite heat detections and National Weather Service fire-weather alerts into one view. This guide explains how wild fire tracking changes across eight US regions, and how to configure a tracker for your home, your trail, your herd or your deadline.

What does a wildfire tracker actually show you?

A wildfire tracker layers four independent data streams on one map: official incident records from federal and state agencies, mapped fire perimeters, satellite thermal detections, and fire-weather alerts issued by the National Weather Service. US Wildfire Tracker combines all four and adds a probability score to each detection.

Those four streams answer four different questions. The incident record tells you a fire exists and has a name, an acreage and a containment figure. The perimeter tells you where its edge was when it was last mapped. The satellite detection tells you where heat was radiating during the last overpass. The alert tells you whether the weather is about to make everything worse.

Confusing them is the single most common mistake in wildfire tracking, and it is the reason a wildfire tracker has to label its layers rather than blend them. A satellite hotspot is not a fire. It is a pixel in which an instrument measured a mid-infrared signal strong enough to trigger a detection algorithm. NOAA notes that those algorithms begin to respond when an active fire occupies about 0.01 percent of the pixel footprint at a temperature of roughly 800 K or above.

The incident record: the fire's identity document

An incident record is the authoritative entry an agency creates when a fire is reported. It carries the fire name, discovery date, acreage, containment percentage, incident type, managing organization and, when the agency supplies it, total assigned personnel. On US Wildfire Tracker every one of those fields appears in the per-fire detail panel alongside a "Last NIFC update" timestamp.

That timestamp matters more than the acreage. Agencies refresh incident records on their own schedules, usually after a morning or evening operational briefing. A record showing 40 percent containment may be describing a situation that changed twelve hours ago. Reading the timestamp before the number is the habit that separates useful wildfire tracking from false confidence, and every good wildfire tracker puts that timestamp beside the figure.

The perimeter: the shape, not the edge

A perimeter is a polygon drawn from infrared aircraft flights, GPS tracks walked or driven by crews, or satellite imagery. It represents the fire's mapped boundary at a specific moment. Perimeters typically update once or twice a day on active large incidents and far less often on small ones, so a fresh-looking outline can be a day old.

US Wildfire Tracker draws the official perimeter for incidents that have one, and can also draw a historical perimeter so you can see how the footprint grew. Where no perimeter exists, the wildfire tracker falls back to a point marker, which is normal for new starts and for the thousands of small fires that never get flown.

The satellite hotspot: heat, with a clock on it

Thermal detections come from three families of instrument. MODIS flies on NASA's Terra and Aqua satellites, launched in December 1999 and May 2002, and detects hot spots at 1,000 meters per pixel. VIIRS flies on Suomi NPP, launched October 2011, and NOAA-20, launched November 2017, and resolves 375 meters per pixel. GOES sits in geostationary orbit and scans continuously.

NASA's Earth Observatory puts the difference plainly: VIIRS makes fire observations about three times more detailed than MODIS, so it detects many small and low-temperature fires that MODIS misses. That is why a modern wildfire tracker, and any serious wild fire tracker built on the same feeds, weights a recent VIIRS detection more heavily than an older MODIS one when it scores confidence.

The fire-weather alert: tomorrow's problem, today

National Weather Service Red Flag Warnings and Fire Weather Watches are the only layer on a wildfire tracker or wild fire tracker that looks forward rather than backward. The NWS glossary defines Red Flag criteria as a dry spell plus a National Fire Danger Rating System reading of high to extreme, with sustained wind averaging 15 mph or more, relative humidity at or below 25 percent, and temperature above 75 degrees Fahrenheit.

Local offices tighten or loosen those thresholds for their own fuels. The NWS Chicago office, for example, uses sustained 20-foot winds of 20 mph or higher, afternoon relative humidity under 25 percent, and 10-hour fuel moisture at 8 percent or less. A Fire Weather Watch goes out up to 72 hours ahead; the Red Flag Warning follows within 24 hours of the event.

The probability score: a way to rank the noise

On a busy August afternoon a national hotspot feed behind a wildfire tracker can contain thousands of points, and only a fraction of them are wildfires. US Wildfire Tracker assigns each detection a probability tier that fuses three things: whether an official NIFC record is linked to it, how fresh the NIFC perimeter is, and how recent the VIIRS, MODIS or GOES heat signal is.

Detections scoring below 25 percent are hidden by default as weak signals and can be switched on when you want the full picture. Outdated records can also be toggled back on. The app warns explicitly that a hotspot may reflect a prescribed burn or an industrial heat source rather than a wildfire, which is exactly the caution NOAA attaches to its own data.

If you want the mechanics of each layer in more depth, the companion guide on how a fire tracker works end to end walks through the same stack from ignition to containment, including the detection algorithms themselves.

Which agencies stand behind wild fire tracking?

Wild fire tracking in the United States rests on ten Geographic Area Coordination Centers, each responsible for mobilizing crews, aircraft and equipment inside its own region and for publishing the intelligence products a wildfire tracker consumes. Understanding those ten centers is the fastest route to competent wildfire tracking anywhere in the country. The National Interagency Fire Center in Boise, Idaho, coordinates between them.

The ten centers are Alaska, Eastern Area, Great Basin, Northern California, Northern Rockies, Northwest, Rocky Mountain, Southern Area, Southern California and Southwest. They are not identical. The Southern Area alone covers 13 states plus Puerto Rico and the US Virgin Islands, stretching from Virginia south to the Gulf and west to Texas.

Each center posts a preparedness level from 1 to 5 that summarizes how stretched its resources are. On September 10, 2026 the Rocky Mountain Area sat at level 2 against a national level of 3, the Northwest sat at 3, and Alaska sat at 1 as its season closed. Those numbers are the fastest single read on where the national firefighting system is under strain.

Who owns the ground changes who owns the data

Land ownership decides which agency writes the incident record. The US Forest Service manages national forests, the Bureau of Land Management manages public rangeland, the National Park Service manages parks, and the Bureau of Indian Affairs and Fish and Wildlife Service manage their own estates. State forestry agencies protect state and most private land.

The Northwest Coordination Center coordinates across all of them for Oregon and Washington: BLM, the Forest Service, the Oregon Department of Forestry, Fish and Wildlife, the Bureau of Indian Affairs, the Washington Department of Natural Resources and the Park Service. A single fire crossing an ownership boundary can therefore appear in two agencies' feeds with two different acreage figures on the same afternoon.

That is precisely the problem a wildfire tracker exists to solve, and it is why a single-agency page is not a substitute for one. Rather than asking you to check eight agency pages, a wildfire tracker pulls interagency records and perimeters from the NIFC and WFIGS services, satellite heat from NASA and NOAA, and alerts from the National Weather Service API, then presents one incident with one detail panel and official links back to the source.

Human causes dominate, but not everywhere

NIFC publishes ignition causes broken out by geographic area, and the regional contrast is stark. In 2025 the Southern Area logged 36,040 human-caused wildfires and only 1,048 lightning fires. The Northwest logged 2,936 human-caused starts against 1,682 from lightning. Alaska recorded 248 lightning fires, more than its 217 human-caused ones.

Nationally, NIFC's published totals for 2025 were 69,556 human-caused wildfires and 8,294 lightning-caused wildfires, adding to the 77,850 fires the agency recorded for the year, according to the agency's human-caused and lightning-caused statistics tables.

The practical consequence for wild fire tracking is timing, and it should change how often you refresh a wildfire tracker. Where humans start most fires, ignitions cluster around holidays, weekends, road corridors and property boundaries, and they happen at all hours. Where lightning dominates, ignitions arrive in storm-driven bursts and often smoulder for days before a satellite sees them.

Across the ten years 2016 to 2025 in NIFC's own table, the United States averaged roughly 63,200 wildfires and about 7.05 million acres burned per year. Those are our calculations from the agency's published annual figures, and NIFC cautions that data before 1983 was not collected under current reporting processes, so longer comparisons are unreliable.

Pacific Northwest: what does a wildfire tracker show?

In Oregon and Washington a wildfire tracker spends most of July, August and September east of the Cascade crest, and wildfire tracking west of the crest is largely a smoke exercise. The Northwest Coordination Center in Portland runs the region, and its 2026 season was severe enough that Washington reported 18 large uncontained fires burning more than 450,000 acres with over 8,000 personnel assigned.

The Cascades split the region into two fire climates. West of the crest, Douglas-fir and hemlock forests are wet enough that fires are rare but capable of extreme behavior when an east wind arrives. East of the crest, ponderosa pine, sagebrush steppe and the Columbia Basin's grass and wheat stubble cure early and burn fast.

The east wind is the variable that matters

NIFC's September 1, 2026 outlook described how a single dry cold front on August 1 produced sustained 20 to 30 mph winds with gusts of 40 to 50 mph across eastern Washington, the Columbia Basin and eastern Oregon. Three new large fires near Spokane damaged or destroyed more than 800 structures inside the city.

Predictive Services put the probability of at least one moderately strong east-wind day in September at elevated, noting that three of the four La Nina to El Nino transitions since 1979 produced a day with a 90th-percentile east-wind pressure gradient. When your wildfire tracker shows a Red Flag Warning for an east-wind event in this region, treat it as a category change, not a nuance. No other single input shifts Pacific Northwest wild fire tracking as sharply.

Who protects what, and why acreage figures differ

The Oregon Department of Forestry describes itself as the state's largest fire department and protects 16 million acres of forest, an asset it values at $60 billion. Oregon does not run one statewide fire season: the State Forester declares fire season district by district, so southern Oregon is typically under restriction weeks before northwest Oregon.

Washington DNR runs its own protection districts and imposed a burn ban across its Northeast and Southeast Regions from July 17, 2026. Because state, federal and private protection interleave, the same fire can be reported by two organizations. A wildfire tracker that keys on the interagency record avoids showing you the same incident twice, which is one practical test of whether a wild fire tracker is fusing data or merely stacking it.

Smoke is the second Pacific Northwest problem, and it travels far beyond the fire. NIFC's Northern Rockies discussion for August 2026 noted that heavy smoke drifting east from Washington and Oregon slowed surface heating in Montana and Idaho for days at a time, actually suppressing fire behavior there. If you are tracking air quality rather than flame, pair your wildfire tracker with the forest fire smoke tracker guide.

California: how do you track wild fires year-round?

California is the only state a wildfire tracker must watch in every month, which makes year-round wildfire tracking a requirement rather than a preference. Two coordination centers split it: Northern California operations in Redding and Southern California operations in Riverside. Northern California typically records eight significant fires in September, four in October and one or fewer in November and December.

That statistical curve is the backbone of California wild fire tracking. The north burns on a summer timber-and-lightning cycle. The south burns on an autumn and early-winter wind cycle that runs long after the north has cooled. A wildfire tracker configured for one half of the state will miss the other half's peak entirely.

Northern California: lightning sieges and dry fuels

Predictive Services in Redding calculates regional Energy Release Component values from 122 Remote Automated Weather Stations. In August 2026 those values sat near or above the 85th percentile for most of the month and touched near-record highs from August 3 to 11 against a 21-year dataset.

Lightning is the wildcard. The 2000 to 2025 Vaisala August average for northern California is nearly 8,400 strikes; through August 26, 2026 fewer than 300 had been observed. A quiet lightning month keeps ignition counts down, but it does nothing to rehydrate fuels, so the risk simply waits for the next ignition source.

Ignition volume tells the same story from the other side. Northern California averaged 15.1 daily wildfire ignitions through August 26, 2026, below the 21.2 daily average for August across 2008 to 2025. Six large fires were reported through August 26 against a regional August significant-fire average of 16.8 across 1992 to 2025.

Southern California: the offshore wind calendar

Southern California's fire year is governed by offshore winds. Through most of August 2026 the region ran 2 to 8 degrees Fahrenheit above normal with routine afternoon winds of 15 to 25 mph gusting to 40 mph over mountain ridges and through desert passes, and live fuel moisture mostly between 60 and 80 percent.

Live fuel moisture is the number that decides whether an offshore wind event produces a nuisance fire or a disaster. When chaparral drops toward the low 60s and an offshore gradient sets up, a wildfire tracker's Red Flag polygon and its nearest hotspot cluster become the two things worth refreshing every few minutes. That pairing is the core of southern California wild fire tracking.

Predictive Services expected fewer Santa Ana events than normal in autumn 2026 and thought the first Gulf of Alaska storm would likely arrive before the first Santa Ana wind event. That sequence matters: a wet frontal system ahead of the wind season shortens the dangerous window considerably. For county-level detail, see the dedicated California fire map guide.

Southwest: when does wild fire tracking matter most?

The Southwest inverts the national calendar. Arizona and New Mexico burn hardest from April into early July, before the North American Monsoon arrives, and a wild fire tracking routine built for August peaks will miss the region's most dangerous six weeks entirely. Set your wildfire tracker for spring here, not late summer.

The Southwest Coordination Center manages both states through dispatch centers in Albuquerque, Alamogordo, Silver City, Prescott, Springerville and Tucson. Fires here run through ponderosa pine at elevation, pinyon-juniper at mid-slope, and grass and chaparral below, and the elevation band a fire occupies predicts its behavior more reliably than its acreage does.

The monsoon is the switch, and it is unreliable

Monsoon onset normally ends the Southwest's critical period. In 2026 it did not arrive cleanly. NIFC reported the August monsoon was weaker than normal because of disruptions from Pacific tropical systems, with eastern New Mexico running 5 to 10 degrees Fahrenheit above normal and most locations recording less than an inch of rain for most of the month.

NIFC also noted large fires emerging in New Mexico in early August, which the agency called very unusual. That is the signal to watch on a wildfire tracker in this region, and the one most casual wild fire tracker users overlook: not a single big fire, but new large-fire starts appearing in a month that should be wet. Many storms produced lightning while remaining too dry or short-lived to help.

What a Southwest incident record looks like

Roughly a third of Arizona and New Mexico is federal land, so most significant incidents carry a Forest Service, Park Service, BLM or Bureau of Indian Affairs managing organization. Those incidents get InciWeb pages, mapped perimeters and infrared flights, which makes the Southwest one of the better-documented regions on any wildfire tracker or forest fire tracker.

NIFC's 2025 cause statistics show 1,658 human-caused fires and 821 lightning-caused fires in the Southwest geographic area. That near two-to-one ratio understates lightning's importance, because lightning fires here start in remote high country and are far more likely to grow large before anyone reaches them.

NIFC expected fire potential in Arizona to stay more active than a typical October in 2026 because of persistent warmth, and forecast that December would likely stay drier than normal with storm tracks displaced north and west. Long-term fuel recovery in the Southwest depends on winter moisture that a strong El Nino does not reliably deliver to these two states.

Rockies: what does a wildfire tracker show at altitude?

The Rockies split across three coordination centers: Northern Rockies for Montana, northern Idaho and the Dakotas; Rocky Mountain, based in Lakewood, Colorado, for Colorado, Wyoming, Nebraska, Kansas and South Dakota; and Great Basin, based in Salt Lake City, for Nevada, Utah and southern Idaho. A wildfire tracker set to a single state here will miss the regional picture, so treat wildfire tracking in the Rockies as a three-center job.

Elevation controls everything. Fires that start in valley grass move fast and die at the timber edge. Fires that establish in subalpine fir and lodgepole above 8,000 feet can burn for weeks, and their perimeters change slowly enough that a daily map refresh is genuinely sufficient.

Terrain breaks satellite geolocation

NOAA warns that fire pixels detected over mountain ranges and steep terrain can show larger locational errors introduced by the terrain correction applied to satellite geolocation data. In practice a hotspot in the Bitterroots or the San Juans can plot several hundred meters from the actual flame front.

That is why a wildfire tracker's probability score should weight a linked official record above a raw detection in mountainous country. Mountain wild fire tracking is the clearest case for scoring rather than plotting. If a cluster of hotspots sits near a named incident with a mapped perimeter, trust the perimeter for location and the hotspots for activity. If the hotspots stand alone on a ridge, treat the position as approximate.

The Great Basin is the region's fast-moving half

Cheatgrass and sagebrush respond to weather in hours rather than days. NIFC recorded the Great Basin moving to preparedness level 5 at the start of August 2026, dropping back to 3 after mid-month moisture, then returning to 4 as activity surged again. Few regions swing that hard inside four weeks.

The agency also flagged a pattern worth building into your habits: areas that received recent wetting rains saw fire activity resume and increase quickly after only a few warm, dry days. In cheatgrass country a wildfire tracker showing a quiet week means very little, and complacent wild fire tracking is genuinely risky. Fine fuels can return to critical dryness in 48 to 72 hours.

Live fuel moisture in low-elevation Great Basin brush sat mostly between 60 and 90 percent entering September 2026, which NIFC described as supporting extreme fire behavior. Watch for a secondary grass crop after late-season rain, which emerged in eastern Utah and the Arizona Strip and adds a fresh fine-fuel layer to burn later.

Colorado, Wyoming and the wind window

The Rocky Mountain Area returned to normal significant fire potential for September through December 2026, but NIFC warned that autumn brings stronger wind events and that brief periods of elevated potential may occur after stretches of warm, dry weather, generally lasting no more than one or two days.

Those one- and two-day windows are exactly what a fire-weather alert layer is for. In August 2026 most of the Rocky Mountain Area received 75 percent of average precipitation or more, while southwest Wyoming and northwest Colorado were below 25 percent. A wildfire tracker that shows drought-driven contrast within a single state is doing its job, and that contrast is what makes state-level wildfire tracking worth the effort here.

Great Plains: why is wild fire tracking about wind?

On the Great Plains a wildfire tracker is really a wind tracker, and wild fire tracking here is a matter of minutes rather than days. Grass fires here can run at highway speed across open country, and the interval between a satellite detection and a fire reaching a ranch road is often shorter than the satellite's own processing latency. Texas alone recorded 1,078 wildfires for 301,528 acres through early September 2026.

Texas A&M Forest Service is the lead agency for wildfire response in Texas and listed a state preparedness level of 3 in September 2026. Oklahoma Forestry Services, the Kansas Forest Service and Nebraska's state and county systems play the same role further north, working alongside thousands of volunteer fire departments.

Flash drought is the Plains-specific hazard

August 2026 produced a textbook example. Texas A&M Forest Service responded to 313 wildfires for 121,774 acres in August alone, and NIFC forecast above normal significant fire potential across Texas, Oklahoma, Arkansas, Louisiana, Mississippi and southwestern Alabama for September.

Flash drought matters for wild fire tracking because it decouples fire risk from the seasonal calendar. Fuels that were green in July can be receptive in mid-August. The wildfire tracker layer that reflects this fastest is the fire-weather alert, because NWS offices adjust Red Flag criteria to the fuel state they are actually observing.

Human ignition dominates, and prevention is measurable

Texas A&M Forest Service states that nine out of 10 wildfires in Texas are human-caused. Debris burning is the leading human cause and equipment use, including vehicles, trailers and ATVs, is second. Parking a hot vehicle on cured grass is a documented ignition mechanism, not folklore.

Burn bans on the Plains are hyper-local. Each Texas county sets and lifts its own burn ban through the county judge or commissioners court, which means a 60-mile drive can cross three different legal regimes in an afternoon. A statewide map will not tell you the rule where you are standing.

The wind-shift row is the one Plains residents underestimate. A fire 12 miles to your southwest under a south wind is a different fire the moment a dry front swings the wind to the northwest, because the long flank becomes a wide head fire. When you track fires here, track bearing and forecast wind direction, not just distance.

Southeast: how does a forest fire tracker read smoke?

The Southeast burns more often than anywhere else in the country and makes headlines least. NIFC recorded 36,040 human-caused wildfires in the Southern Area in 2025, more than every western coordination center combined. Most are small, fast and extinguished within hours, which makes a forest fire tracker's probability tiers essential rather than optional. Nowhere else does wildfire tracking depend so heavily on filtering.

The Southern Area covers 13 states from Virginia to Texas plus Puerto Rico and the US Virgin Islands. Its fire season is bimodal: a late-winter and early-spring peak from February to April before green-up, and an autumn peak after leaf drop, with drought-driven exceptions in any month.

Prescribed fire is the region's defining signal

The South burns more acres on purpose than the rest of the country burns by accident. NIFC recorded 6,058,508 acres of prescribed fire nationally in 2019, of which 4,236,882 acres were burned by state and other non-federal partners, the great majority of that in southern pine.

For anyone using a forest fire tracker in Georgia, Florida, Alabama or the Carolinas, this is the number one cause of confusion. A field of satellite hotspots in longleaf pine in February, seen on any wildfire tracker, is far more likely to be a planned burn than a wildfire. That is why US Wildfire Tracker states plainly that a detection may reflect a prescribed burn, and why the probability tier that checks for a linked NIFC incident record matters so much here.

Storm debris changes the fuel model for years

NIFC's 2026 Southern Area assessment listed fuel concerns ranging from recently cured fine fuels to drought and beetle kill, along with tornado, ice storm and hurricane damage. It singled out forests across the southern Appalachians, Piedmont and coastal plain damaged by Hurricane Helene, noting that heavy fuels in the hurricane's footprint consume completely once ignited.

That is a multi-year condition. Downed timber does not disappear after one season, so a wildfire tracker user in western North Carolina or upstate South Carolina should expect longer-duration incidents in storm-damaged terrain than the region's historic averages suggest. Our South Carolina fires guide covers that state's tracking specifics in detail.

South Florida is the region's other outlier. NIFC described late-summer 2026 drought there as among the most intense on record for the season, with extreme drought coverage second only to 2015, and forecast above normal significant fire potential for the peninsula in September. Low water levels in the Everglades are themselves a fire risk factor.

Alaska: what makes wild fire tracking different there?

Alaska is the one place in the United States where lightning starts more fires than people do. NIFC recorded 248 lightning-caused fires against 217 human-caused fires in Alaska in 2025. Wildfire tracking here works on a compressed calendar, in terrain with almost no roads, and against fuels that behave unlike anything in the lower 48.

The Alaska Interagency Coordination Center sits on Fort Wainwright near Fairbanks and coordinates the Bureau of Land Management, the State of Alaska Department of Natural Resources, the Forest Service, the Park Service, the Bureau of Indian Affairs and the Fish and Wildlife Service. Wildland fires are reported statewide to 1-800-237-3633.

Black spruce and duff burn on a different clock

Alaska's Interior burns in black spruce, shrub and grass over deep organic duff. Duff layers hold heat for weeks, so a fire declared quiet can resurface after rain. That single property changes how you read a wildfire tracker in Alaska: a low containment percentage on an Alaskan fire is normal, not alarming, and often reflects strategy rather than loss of control.

The 2026 Mukluk Fire near Tok illustrates the pattern. It started August 17, 2026 in black spruce, shrubs and grass, reached 7,335 acres at 29 percent containment, and destroyed 50 single residences plus 108 outbuildings, garages, sheds and workshops. NIFC described it as emerging during a very dry and windy day and immediately requiring a Complex Incident Management Team.

The season starts and ends abruptly

Alaska's fire season runs roughly May through early August, driven by long daylight and Interior thunderstorms. It ends when the rain arrives. NIFC's September 2026 outlook recorded season-ending rains beginning in the last week of August, dropping fire weather indices to low across the western two-thirds of the state.

Snow normally reaches most Interior locations by mid-October and pushes south of the Alaska Range into south-central Alaska and the Copper River Basin by early November, effectively ending the fire year. Alaska's preparedness level had already fallen to 1 by September 9, 2026, the lowest on the five-point scale.

Because the season is short and intense, Alaskan users should treat a wildfire tracker as a June-and-July instrument, and treat wild fire tracking as effectively closed by late September. Configure wildfire tracker proximity alerts before breakup and expect the map to go quiet in September. Smoke, however, outlasts flame: Interior smoke can reduce air quality in Fairbanks and Anchorage long after fire growth stops.

Hawaii: why do the islands need a wildfire tracker?

Hawaii needs a wildfire tracker as much as any mainland state: it burns a larger share of its land area in a typical year than most western states, and almost every fire is started by a person. University of Hawaii research found that over 99 percent of known wildfire causes in Hawaii are due to human activities, unlike much of the mainland where lightning contributes heavily.

The scale surprises people. Research summarized by the university found the state averaging more than 1,000 fires burning over 20,000 acres each year in the 2005 to 2011 study period, with the area burned annually having increased more than fourfold in recent decades.

Abandoned agriculture created the fuel bed

The underlying cause is land-use change. Land under active grazing or cultivation in Hawaii fell from about 2.6 million acres in 1960 to roughly 970,000 acres, a reduction of more than 60 percent. Dry non-native grasslands and shrublands now compose 24 percent of Hawaii's total land cover.

Those grasslands sit between neighborhoods and forest, which is why ignitions cluster in developed areas while the largest burned areas occur in grass. The published research found that 95 percent of Hawaii fires were under 4 hectares, while 93 percent of the area burned came from fires of 40 hectares or more.

Hawaii's Red Flag criteria are their own thing

Do not apply mainland thresholds here. The NWS Honolulu criteria updated for 2026 trigger a Red Flag event on leeward portions of the state when relative humidity is at or below 45 percent for two or more hours and sustained wind is at or above 26 mph for two or more hours at specific stations, with Keetch-Byram Drought Index eligibility.

Warnings are issued island by island, which is the right granularity for a place where windward and leeward conditions differ by a factor of ten in rainfall. When you filter a wildfire tracker to Hawaii, the alert polygon your wild fire tracking depends on is the one covering your island's leeward side, published by the NWS Honolulu forecast office.

Hawaii's 2026 late summer was quiet by these measures. NIFC recorded no Red Flag Warnings in Hawaii during August 2026, with the largest fire of the month burning a little over 200 acres on the Big Island on August 11. Hurricane Lala passed August 14 to 16 and dropped up to 40 inches on parts of the island, though NIFC noted its strong winds increased hazard fuel loading for later.

Homeowners: how to set a wildfire tracker for a house?

A homeowner needs a wildfire tracker to answer one question reliably, and everything else in wildfire tracking is secondary to it: is anything burning that could reach my address, and how much time would I have. Everything else is secondary. That means configuring for proximity and bearing rather than for national coverage.

Start by enabling browser geolocation so the wildfire tracker can list fires near you within a set distance in miles. US Wildfire Tracker uses location only to find nearby fires and does not store, sell or share it. Then choose a working radius: 5 miles for immediate threat, 25 miles for planning, 50 miles for smoke.

1. Open the live map at wildfire-map.org, allow location, and confirm your position on the basemap.
2. Set the nearby distance so the fire list panel shows incidents within 25 miles of your address.
3. Turn on the fire-weather alert layer and check whether a Red Flag Warning or Fire Weather Watch covers your county today.
4. For every fire in the list, open the detail panel and read three fields in order: last NIFC update, last satellite heat, and percent contained.
5. Note the bearing from the fire to your house, then compare it with the forecast wind direction for the next 12 hours.
6. If a fire is within 10 miles and upwind, check your county emergency management channel for evacuation status before doing anything else.

Why bearing beats distance

Distance alone is a weak predictor. A fire 15 miles upwind on a Red Flag day is a more serious problem than a fire 4 miles downwind with a mapped perimeter that has not grown in 36 hours. Reading the wind direction alongside the fire's position converts a static wildfire tracker into a rough time estimate.

The Great Plains wind-shift problem applies to houses everywhere. If a front is forecast to swing the wind 90 degrees, the fire's long flank becomes a broad head fire. Anyone who lives along that flank moves from safe to threatened in the time it takes the front to pass.

Set up before the season, not during it

The worst time to learn a wildfire tracker's controls is during an evacuation warning. Do the wildfire tracker configuration in the quiet season: install the extension, grant location, set your radius, learn where the refresh button is, and practise reading a detail panel on a fire that does not concern you.

Also decide in advance what you will do at each trigger. Many western counties use a three-stage system commonly described as Ready, Set, Go, with the last stage meaning leave immediately. Deciding which stage prompts you to load the car is a decision to make in June, not at 2 a.m. in October.

The fire tracker near me guide covers the 60-second proximity check in detail, including what radius to use in dense suburbs versus open rural country.

Hikers: what wild fire tracking do you do pre-trip?

Hikers and backpackers face a specific version of the problem: you need to make one good decision before you lose connectivity, then live with it for days. Wild fire tracking for a trip is therefore a planning exercise, not a monitoring exercise, and a wildfire tracker should be part of the packing routine.

Do the check the evening before departure and again at the trailhead. Look for active incidents anywhere inside your route corridor plus a generous buffer, any Red Flag Warning covering the days you will be out, and any fire restrictions on the managing agency's own page linked from the incident record.

1. Filter the wildfire tracker to the state you will be hiking in and scan the full fire list, not just the nearest few.
2. Identify every incident within 30 miles of your route, including small ones with no mapped perimeter.
3. Check the fire-weather layer for Red Flag Warnings or Fire Weather Watches covering your trip dates.
4. Open the official links in each incident record to check trail, road and area closures before you drive.
5. Screenshot the wildfire tracker and the fire list so you carry the last known picture into the backcountry.
6. Agree a bail-out trigger and an alternate exit trailhead with everyone in the party.

Smoke will affect you before flame does

Statistically the far more likely wildfire impact on a hike is smoke, not entrapment. Smoke travels hundreds of miles and can degrade air quality in valleys with no fire within a day's drive. The EPA Air Quality Index uses six color-coded categories, and an AQI value of 100 generally corresponds to the level of the short-term national ambient air quality standard.

Above 150, described as Unhealthy, some members of the general public may experience health effects and sensitive groups more serious ones. Sustained aerobic effort at altitude in that range is a poor idea. Above 200, Very Unhealthy, the official language is a health alert: the risk of health effects is increased for everyone.

The AQI categories and their official descriptions are published by EPA AirNow. Pair the numbers with a wildfire tracker's smoke overlay so you know both how bad the air is and which fire is producing it.

Ranchers: how does wild fire tracking protect stock?

Ranchers use a wildfire tracker differently from homeowners because livestock cannot be evacuated in ten minutes and pasture cannot be evacuated at all. The operative question is not whether a fire will reach the house but which pasture, which water source and which access gate is in the path.

On the southern Plains that calculation is compressed by grass-fire speed. Texas A&M Forest Service, the lead wildfire agency for the state, recorded 1,078 wildfires for 301,528 acres in 2026 through early September, and NIFC forecast above-normal significant fire potential across Texas, Oklahoma, Arkansas, Louisiana, Mississippi and southwestern Alabama for that month.

Track wind and burn bans, not just fires

The two most useful layers for an agricultural operation are the National Weather Service fire-weather alerts and, off-map, the county burn ban status. Each Texas county sets and lifts its own burn ban through the county judge or commissioners court, and neighbouring counties can be on opposite settings on the same day.

Equipment is the second-largest human cause of wildfire in Texas after debris burning, and haying, baling and welding season overlaps precisely with peak fine-fuel dryness. A wild fire tracker showing a Red Flag Warning across your county is a reason to postpone equipment work, not just a reason to watch the horizon.

What the map can and cannot tell you about pasture

A wildfire tracker shows fire location, official perimeter where one exists, and heat detections. Agricultural wild fire tracking has to fill the rest in from local knowledge. It does not show fuel load, fence status or road conditions. Satellite pixels are also coarse for agricultural scale: NOAA cautions that fire pixels do not translate into absolute fire area and should serve as a coarse indicator only.

That caution matters most on rangeland, where a single VIIRS pixel covers roughly 375 meters on a side and a GOES pixel considerably more. Use the wildfire tracker's hotspot cluster to know that something is burning and roughly where. Use the official perimeter, if one exists, to judge how much ground has actually been affected.

Grazing itself is a mitigation tool. In Hawaii, researchers have pointed to modifying vegetation and using animals to graze wide areas as a way to reduce risk at landscape scale, and the same logic applies in cheatgrass country. A grazed firebreak is visible on the ground long before it is visible on any wildfire tracker.

Journalists: how do you source a wildfire tracker?

Reporters need a wildfire tracker for speed and a paper trail for publication, which makes newsroom wildfire tracking a two-tool job. The workflow is therefore two-stage: use the map to find and rank incidents in seconds, then follow the official links in the detail panel to the agency record you will actually cite.

Never cite a map as the source of a number. Cite the agency. A wildfire tracker exists to get you to that agency record quickly, which is why each incident carries official links, a "Search on InciWeb" action, and explicit timestamps for the last NIFC update and the last satellite heat detection.

The four numbers to check before filing

Acreage

Comes from the managing agency and often lags reality by hours; note the update time alongside it.

Containment

The percentage of the perimeter secured by completed control line, not the percentage extinguished.

Personnel

Total assigned resources when NIFC publishes them; a useful proxy for how seriously the incident is being treated.

Structures

Damage assessment figures change repeatedly; attribute them to the assessment team and the date.

Timestamps are the reporting discipline that prevents the most common wildfire error. A story that says a fire is 40 percent contained without saying when that figure was published is describing a moment, not a state. NOAA notes that HMS products are timestamped in UTC, so subtract 5, 6, 7 or 8 hours for Eastern, Central, Mountain or Pacific time, and one hour fewer during daylight saving time.

Context numbers that survive fact-checking

For seasonal context, use NIFC's published annual totals rather than derived estimates. The agency recorded 77,850 fires and 5,131,474 acres in 2025, 64,897 fires and 8,924,884 acres in 2024, and 58,950 fires and 10,122,336 acres in 2020. Those figures come from the NIFC wildfires and acres statistics page.

For cost context, NIFC's suppression table records combined Forest Service and Interior spending of $4,389,000,000 in 2021, $3,549,000,000 in 2022 and $3,166,300,000 in 2023. For year-to-date context in 2026, NIFC reported 8,238,284 acres burned as of August 31, which it put at 166 percent of the previous ten-year average, from 52,253 fires at 126 percent of average.

The national preparedness level is the single best one-line indicator of system strain, and NIFC reported it staying at five on a one-to-five scale throughout August 2026, with support needed from active-duty military, Australia and New Zealand. That single figure tells an editor more about national capacity than any individual fire does.

Travelers: how to plan a trip around a fire tracker?

Travelers need a wildfire tracker for route risk and air quality, usually across several states at once, so multi-state wildfire tracking is the default posture. The right posture is a national view first, then a state filter for each state you will drive or fly through, checked at the planning stage and again 24 hours before departure.

NIFC publishes a normal fire season progression product based on 1992 to 2020 fire occurrence data, expressed as the probability of a fire greater than 300 acres within 25 miles. That framing is exactly the one a traveler needs, because it describes the chance of encountering a disruptive fire near a point rather than the chance of a fire anywhere.

Match the trip to the regional calendar

Smoke on interstates is an underrated hazard in the Southeast, where night-time smoke and fog combine into dense, localized visibility drops. In the West the more common disruption is a road closure that adds hours to a route, which a wild fire tracker gives you enough warning to avoid entirely.

What to do when a fire appears on your route

US Wildfire Tracker includes directions away from a fire through Google Maps, Apple Maps or Waze, and a share link so you can send a specific incident to whoever is travelling with you. Use those before you are close, not after. A fire that has closed a highway has usually also filled the alternate route with traffic.

For international and cross-country travelers, remember that the picture changes daily. NIFC's own outlooks are issued monthly on the first of the month, while incident records and satellite detections refresh continuously. The live fire tracker guide explains which timestamps update on which cadence.

How do you set up a wildfire tracker in five minutes?

Setting up a wildfire tracker takes about five minutes and involves three decisions before any real wildfire tracking begins: where you want it to live, how far around you it should look, and which layers you want on by default. US Wildfire Tracker is free, requires no account, and runs either as a website or as a Chrome side-panel extension.

1. Open the live map in any browser to check that the national view loads and shows current incidents.
2. If you use a Chromium browser, install the extension from the Chrome Web Store listing and pin it to the toolbar.
3. Open it in the side panel so the map sits beside your work, or open it in a full tab when you want the whole screen.
4. Allow location if you want fires near you; the app uses it only to find nearby fires and never stores or shares it.
5. Choose your default view: national for travel and news, a single state for local monitoring, or fires near me for home.
6. Decide whether to show weak signals below 25 percent probability and whether to show outdated records; leave both off for a clean view.
7. Open one fire's detail panel and read every field once so the layout is familiar before you need it under pressure.

Side panel or full tab?

Side panel

Best for passive monitoring during a work day; the map stays visible while you use other tabs.

Full tab

Best for investigation: reading perimeters, comparing hotspot clusters, and following official links.

Website only

Best on browsers without extension support, on a phone, or on a machine you do not control.

State filter

Best for residents; covers all 50 states plus the District of Columbia.

Fires near me

Best for households and travelers; lists incidents within a set distance in miles.

Data refreshes automatically every few minutes while the wildfire tracker is open, and there is a manual refresh button for the moments when you want certainty rather than patience. If a refresh fails, the app shows the last saved results rather than an empty map, which is the correct behavior when connectivity is poor near a fire.

There are no ads and no third-party ad trackers inside the extension, and the whole tool is free. The step-by-step installation walkthrough, including troubleshooting for denied location permissions, lives in the fire tracker app setup guide.

How accurate is a wildfire tracker, and what lags?

A wildfire tracker is accurate about what it says and imprecise about what you infer, and honest wildfire tracking depends on knowing which is which. Each layer carries its own known error: satellite geolocation offsets, detection thresholds, processing latency and agency update schedules. NOAA publishes those figures openly, and understanding them turns a map from a rumour into an instrument.

Start with latency, because it is the number people guess wrong most often. NOAA reports that GOES full-disk Level 1 data becomes available within roughly 20 to 30 minutes of observation, while the contiguous US imaging sector is usually available within 10 to 15 minutes, with fire processing adding another 5 to 15 minutes.

Polar-orbiting instruments are slower. NOAA states that MODIS and VIIRS Level 1 data becomes available within about 1 hour 30 minutes to 2 hours 30 minutes of observation, with fire processing adding a further 5 to 10 minutes. Quality-controlled HMS output can add another 1 to 3 hours on average while image analysts assess the data.

What satellites can and cannot see

NOAA states there is no absolute size above which a fire will be detected. Traditional algorithms used with MODIS, VIIRS and GOES begin to respond to active fires occupying at least 0.01 percent of the pixel footprint, assuming an average fire temperature of at least 800 K. For a 1 km pixel that means an active area of at least 100 square meters.

Detection performance degrades at high view angles, because pixels enlarge toward the edge of the swath. It also degrades under cloud, under dense forest canopy and near water bodies where the land-water separation may be imperfect. A small, smouldering, canopy-covered fire under an overcast sky may simply not appear.

There is also a peculiar failure mode worth knowing. NOAA describes cases in which the VIIRS 375 m product detected part of a very tall, superheated smoke plume alongside the surface fire during explosive growth at night, with parallax displacing those pixels laterally away from the true perimeter. Analysts correct these when they can.

The false-positive list you should memorize

NOAA lists the main causes of commission errors in satellite fire products: fresh burn scars and sandy soils that elevate the mid-infrared signal, sun glint on optically bright or specular surfaces such as large solar panel clusters and metallic rooftops, and thermal anomalies from industrial activity including steel mills and gas flaring.

Structure fires in urban environments can also appear. Most of these are removed from the quality-controlled HMS product, but raw feeds carry them. This is the technical reason a wildfire tracker or forest fire tracker should apply a probability score rather than plotting every detection as a fire, and why weak signals below 25 percent are hidden by default in US Wildfire Tracker.

Why a fire can look active after it is out

Three mechanisms produce this illusion. First, an incident record stays published until the agency closes it, so an old record can persist. Second, residual heat in duff, stumps and heavy fuels keeps radiating long after flaming stops, which is routine in Alaskan black spruce and in the Minnesota Arrowhead, where NIFC reported deep-burning organics holding heat through repeated rainfall.

Third, detections accumulate. A cluster on the map may represent several overpasses across two days rather than simultaneous burning. The fix is to read the wildfire tracker's "last satellite heat" and "last GOES heat" timestamps rather than counting dots, and to switch outdated records off unless you are specifically researching history.

Wild fire tracking glossary: what do the terms mean?

Wild fire tracking has a vocabulary borrowed from three professions, and a wildfire tracker surfaces terms from all of them: firefighting, meteorology and remote sensing. These are the terms that appear on a wildfire tracker's interface and in the agency records it links to, defined the way the agencies themselves use them.

Acres

The area inside the fire's mapped perimeter, which includes unburned islands. Not the same as acres consumed.

Contained

The percentage of the perimeter secured by completed control line. A 100 percent contained fire can still be burning inside.

Controlled

A later stage than contained: the line is complete and holding, and the fire is not expected to escape.

Out

No heat remains anywhere within the perimeter. In deep organic fuels this can take months.

Discovery date

When the fire was first reported to an agency, which may be well after ignition.

Incident type

Wildfire, prescribed fire or other incident category recorded by the managing agency.

Managing organization

The agency in operational charge; determines update cadence and where official links point.

Complex

Two or more incidents in the same area managed under a single command organization.

Weather and fuels terms

Red Flag Warning

NWS product issued when critical fire-weather conditions are occurring or expected within 24 hours.

Fire Weather Watch

Issued when those conditions are possible, typically up to 72 hours ahead.

Energy Release Component

An NFDRS index of available energy per unit area at the flaming front; reported in percentiles against history.

Live fuel moisture

Water content of living vegetation as a percentage of dry weight; chaparral in the 60s supports extreme behavior.

Dead fuel moisture

Water content of dead fuels by response time: 1-hour, 10-hour, 100-hour and 1,000-hour classes.

Cured

Vegetation that has dried and lost its green moisture, becoming fully receptive to ignition.

Preparedness level

A 1 to 5 scale describing resource commitment nationally or within a geographic area.

Keetch-Byram Drought Index

A soil and duff dryness index used in the Southeast and Hawaii to gauge fire potential.

Satellite and mapping terms

Thermal anomaly

A pixel whose mid-infrared signal exceeds the background enough to trigger a detection algorithm.

Fire Radiative Power

Energy release rate in megawatts, related to the rate of biomass consumption.

Confidence level

An algorithm's own estimate that a detection represents a real fire, distinct from a tracker's probability tier.

Commission error

A false alarm: industrial heat, sun glint, fresh burn scar or structure fire recorded as a wildfire.

Omission error

A real fire the satellite missed because of cloud, canopy, size or view angle.

Nadir

The point directly beneath the satellite, where pixel geometry and geolocation are most accurate.

Perimeter

A polygon of the fire's mapped boundary at a stated time, from infrared flight, GPS or imagery.

Basemap

The underlying reference map; US Wildfire Tracker uses OpenStreetMap.

Learning eight of these terms removes most of the ambiguity from a wildfire tracker and makes wildfire tracking far less stressful. The two that cause the most misreading in practice are contained, which people hear as extinguished, and acres, which people hear as acres destroyed. The wildfire map guide works through the same vocabulary with worked map examples.
