Idaho Fire Map: Track Idaho Wildfires Live in 2026
A live Idaho fire map brings official incident records and perimeters together with NASA and NOAA satellite heat detections and National Weather Service fire-weather alerts, so you can follow rangeland fires on the Snake River Plain and timber fires in the Panhandle at the same time.
What does an Idaho fire map show right now?
An Idaho fire map layers four public feeds over one basemap: official incident records from the National Interagency Fire Center, mapped fire perimeters, satellite thermal detections from NASA's VIIRS and MODIS instruments and NOAA's geostationary GOES analysis, and active National Weather Service fire-weather alerts.
Satellite heat is the fast layer. Polar-orbiting passes cross Idaho several times a day and the geostationary analysis fills the gaps, so a fresh thermal signal with no matching incident record usually means a start that has not reached a dispatch record yet — common in the Frank Church wilderness country where roads are scarce.
US Wildfire Tracker fuses those feeds on its free live fire map and attaches a fire probability tier to every detection, blending whether an official record is linked, how fresh the perimeter is and how recent the heat is. Weak signals below 25 percent stay hidden by default because they often reflect prescribed burns or industrial heat.
When is Idaho's closed fire season?
Idaho runs a legally defined closed fire season rather than an informal one. Valley County's fire warden office states the rule plainly: "The period from May 10th to October 20th of each year, has been designated as the closed season for fires in the state of Idaho."
Inside that window a burn permit is required. The same guidance notes that during the closed season "it is unlawful for any person to set, or cause to be set, a fire without first having obtained a Burn Permit," available from the local protective district fire warden or the state burn permit website. Campfires are the exception unless critical fire danger closes them too.
Large-fire activity peaks later than the permit season starts. Southern Idaho rangeland typically becomes receptive in late June once cheatgrass cures, while the mountain timber of central and northern Idaho reaches its driest point between late July and mid-September.
Which agencies fight wildfires in Idaho?
Idaho's wildfire response is unusually federal. The Bureau of Land Management describes its Idaho operation as "one of the largest and most complex fire programs in the BLM, protecting approximately 11 million acres of range and forest land in central and southern Idaho and employing nearly 500 people."
That program alone responds to an average of 330 fires burning about 270,000 acres a year, with roughly 50 fire engines, two helicopters, four single engine air tankers, 11 bulldozers, an interagency hotshot crew and four interagency dispatch centers.
The Idaho Department of Lands runs the state program. IDL describes its fire arm as working "in partnership with two Timber Protection Associations and with the support of rural volunteer fire departments and other partners" and as "responsible for fire suppression and prevention on more than 9 million acres of state, private and federal land in Idaho," organized into 12 forest protective districts.
The state's stated tactical goal is aggressive initial attack. IDL says its fire program "focuses on initial attack with the goal of keeping fires at 10 acres or less," a standard that matters because the endowment timber it protects funds Idaho schools.
Rangeland Fire Protection Associations fill the gap on open country. IDL describes them as "nonprofit volunteer firefighting organizations made up of local farmers, ranchers, and landowners," and reports that Idaho's ten RFPAs "protect a combined 9.3 million acres of private, state and federal rangeland." Idaho's first was formed in 2012.
Why is Idaho split between two fire regions?
Idaho is the only state in the Northwest whose wildfire coordination is split between two of the country's ten geographic areas. Northern Idaho belongs to the Northern Rockies geographic area, and southern Idaho belongs to the Great Basin.
The Northern Rockies Coordination Center in Missoula describes its boundary as covering "the States of Montana, North Dakota, and northern Idaho, Yellowstone National Park, and a small portion of South Dakota." The Idaho Department of Lands is listed among its primary cooperating agencies.
The Great Basin Coordination Center in Salt Lake City draws the other half of the line, stating that its geographic area "encompasses Utah, Nevada, Idaho-south of the Salmon River, the western Wyoming mountains and the Arizona Strip." Its Idaho zone centers are Boise, Central Idaho, Eastern Idaho, Payette and South Idaho.
This matters when you read a map. Two adjacent fires can be managed under different coordinating groups with different resource queues, which is one reason containment percentages on either side of the Salmon River can move at very different speeds. Neighbouring Montana sits entirely inside the Northern Rockies area.
Where do Idaho wildfires usually burn?
Idaho burns in two very different landscapes. Southern Idaho's Snake River Plain and Owyhee country is sagebrush and grass, where wind-driven fires cover enormous ground quickly. Central and northern Idaho is mountain timber, where fires burn longer and are harder to reach.
Access shapes outcomes as much as fuel does. Central Idaho contains some of the largest roadless country in the lower 48, so a lightning start there may burn for days before crews can reach it, while a rangeland start near Interstate 84 draws engines within minutes.
BLM's fuels program reflects that reality, treating more than 100,000 acres a year with mechanical thinning, prescribed fire, seeding and fuel breaks intended to give suppression crews a place to stop a running rangeland fire.
| Year | Total fires | Total acres | Human-caused fires | Lightning-caused fires |
|---|---|---|---|---|
| 2025 | 1,302 | 180,935 | 784 | 518 |
| 2024 | 1,450 | 996,762 | 819 | 631 |
| 2023 | 892 | 87,801 | 591 | 301 |
The cause split is the part to notice. In 2024 human starts were 819 of Idaho's 1,450 fires but only about 70,500 of the 996,762 acres, because lightning fires start in country crews cannot reach quickly. NICC cautions that its figures come from the Sit/209 application and "may not reflect final official figures."
What are the largest Idaho wildfires ever?
Idaho's defining fire is the Great Fire of 1910, the event that burned across the Panhandle and into western Montana in a single August. Modern Idaho megafires are smaller but still enormous by national standards, and most of them burn in the southern rangeland or the central mountains.
| Fire | Year | Acres | What made it notable |
|---|---|---|---|
| The Great Fire of 1910 | 1910 | About 3 million (Idaho and Montana) | Hurricane-force winds on August 20 merged thousands of fires; about 86 people died |
| Murphy Complex | 2007 | About 653,000 | Largest Idaho fire since 1910; burned southern Idaho and northern Nevada rangeland in two weeks |
| Mustang Complex | 2012 | More than 330,000 | Lightning-started on the Salmon-Challis National Forest in mountainous pine forest |
| Long Butte | 2010 | More than 300,000 | Burned over 200,000 acres of sage and grass in a single day in south-central Idaho |
| Paddock Fire | 2024 | 187,185 | Idaho's largest fire of 2024, lightning-caused, contained inside about 12 days |
| Wapiti Fire | 2024 | 129,063 | Lightning start near Grandjean in the Sawtooths that burned from July into November |
Two of those entries show how fast rangeland fire moves. NASA recorded that the Long Butte fire "burned over 200,000 acres in a single day" on August 23, 2010, while the Wapiti Fire took more than three months to reach a smaller total in steep, roadless mountain terrain.
What weather drives Idaho fire danger?
Idaho's worst fire days combine strong wind, very low relative humidity and fuels already cured by summer heat. When the National Weather Service expects those to coincide, it issues a Red Flag Warning for the affected fire-weather zones.
The NWS defines a Red Flag Warning as an alert issued "in conjunction with land management agencies, to alert land managers to an ongoing or imminent critical fire weather pattern," used when conditions are occurring or expected shortly. A Fire Weather Watch is the earlier stage, meaning critical conditions are "possible but not imminent or occurring."
Three forecast offices split the state: Boise for southwest Idaho, Pocatello for the southeast and Spokane for the Panhandle. Their fire-weather zones follow terrain rather than county lines, so a warning can cover a valley floor while the ridge above it stays out.
Dry lightning is the other driver. A single storm crossing the Salmon River country can leave dozens of holdover starts smouldering in timber, which is why the number of incidents on a map can climb for days after the storm has passed.
How do evacuations work in Idaho?
Idaho standardized its wildfire evacuation language in 2026. Teton County Emergency Management states that "The State of Idaho is adopting the 'Ready, Set, Go' wildfire evacuation program as the statewide standard for public evacuation messaging, establishing a unified, consistent approach to communicating evacuation risk and action levels across all jurisdictions."
Before that, counties used different systems. Reporting on the change quoted officials describing a patchwork in which some counties used "3-2-1" and others used red, yellow and green, which meant the same warning could mean different things one county line apart.
| Level | Official wording | What to do |
|---|---|---|
| Ready | "Be aware of danger and begin to prepare for a possible evacuation" | Harden the house, pack documents and medication, plan a route |
| Set | "Be prepared to leave at a moment's notice: be packed and ready" | Vehicles loaded, animals moved, monitor your county sheriff |
| Go | "Evacuate immediately when directed by local authorities" | Leave. This level means an immediate threat to life safety |
Authority did not change with the vocabulary. Teton County notes that the messaging "aligns with the statutory authority of Idaho's county sheriffs, who retain responsibility for issuing evacuation orders within their respective counties." Older Level 1, 2 and 3 phrasing still appears in some North Idaho reporting and maps onto Ready, Set and Go respectively.
Idaho is the state that taught us to show our sources rather than blend them. Half the state is dispatched out of one geographic area and half out of another, and a lot of the country that burns has no road within 20 miles, so an official acreage figure can be a day old while the satellite heat is 30 minutes old. We display both timestamps side by side and let you judge. What we will never do is imply that our map outranks a sheriff's evacuation order.The US Wildfire Tracker team — builders of the wildfire-map.org live map and Chrome extension
How do you read an Idaho fire map fast?
Checking Idaho fire activity should take under a minute. This sequence works on the live map or in the Chrome side panel, and it puts proximity ahead of headline acreage.
- Open the map and filter to Idaho, or allow location access to see only fires within a set distance in miles of where you are.
- Read the fire probability tier before the acreage. Weak signals below 25 percent are hidden by default because they often reflect prescribed burns or industrial heat.
- Open the nearest incident and compare three timestamps: last NIFC update, last satellite heat and last GOES heat. Fresh heat under an old perimeter means the fire is still moving.
- Check whether a Red Flag Warning polygon covers your area, since that changes how quickly conditions can deteriorate.
- Confirm evacuation status with your county sheriff or emergency management office, then use the directions-away links if you need to move.
Our fire tracker guide explains how each data layer is produced, and the fires near me walkthrough covers the proximity workflow in detail.
What does wildfire smoke do to Idaho air?
Smoke reaches far more Idahoans than fire does. The state's north-south valleys act as smoke traps: the Treasure Valley, the Palouse and the Panhandle lakes country all collect smoke under late-summer inversions, sometimes from fires hundreds of miles away in Washington, Oregon or British Columbia.
Air quality is reported on the Air Quality Index. The EPA describes it as six color-coded categories, noting that for each pollutant "an AQI value of 100 generally corresponds to an ambient air concentration that equals the level of the short-term national ambient air quality standard for protection of public health."
| Category | AQI | Official description |
|---|---|---|
| Good | 0 to 50 | "Air quality is satisfactory, and air pollution poses little or no risk." |
| Moderate | 51 to 100 | "Air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution." |
| Unhealthy for Sensitive Groups | 101 to 150 | "Members of sensitive groups may experience health effects. The general public is less likely to be affected." |
| Unhealthy | 151 to 200 | "Some members of the general public may experience health effects; members of sensitive groups may experience more serious health effects." |
| Very Unhealthy | 201 to 300 | "Health alert: The risk of health effects is increased for everyone." |
| Hazardous | 301 and higher | "Health warning of emergency conditions: everyone is more likely to be affected." |
The state runs a formal response for those episodes. Idaho DEQ says that when wildfire smoke threatens the state it implements the Wildfire Smoke Event Response Protocol, coordinating with health districts, five tribes, federal agencies and the neighbouring Montana, Oregon and Washington air agencies, and that it "provides a smoke forecast when wildfire smoke impacts Idaho."
DEQ's monitoring network backs that up with instruments "at more than 30 sites statewide," and its data flows hourly to EPA's AirNow. A clear local fire map can still coincide with hazardous air, because the plume that matters may have travelled from another state. Our smoke tracking guide explains how to read plume forecasts against ground monitor readings.
Frequently asked questions about the Idaho fire map
How often does an Idaho fire map update?
It depends on the layer. Satellite thermal detections arrive several times a day from polar-orbiting instruments, with NOAA geostationary heat filling gaps between passes. Official incident records and perimeters follow agency schedules, often once per operational period. US Wildfire Tracker refreshes automatically every few minutes while open and shows the last-update time for each source.
Why is Idaho covered by two coordination centers?
Because the national geographic area boundaries cut through the state. Northern Idaho falls inside the Northern Rockies geographic area coordinated from Missoula, while southern Idaho falls inside the Great Basin, whose Idaho dispatch zones are Boise, Central Idaho, Eastern Idaho, Payette and South Idaho. Statewide totals therefore have to be assembled from two separate sets of statistics.
Is a Red Flag Warning the same as a fire?
No. A Red Flag Warning is a National Weather Service alert about weather, issued with land management agencies when a critical fire weather pattern is occurring or expected shortly. It means a new ignition would spread dangerously, not that a fire is burning. A Fire Weather Watch is the earlier stage, meaning those conditions are possible but not yet imminent.
Where is the National Interagency Fire Center?
In Boise, Idaho, at 3833 S. Development Avenue. NIFC is the national hub for interagency wildland fire coordination and is the focal point for overseeing coordination across the ten geographic areas. Its incident records and interagency perimeter services are one of the core data layers behind any credible US fire map, including this one.
Does the map show fires in wilderness areas?
Yes, and that is where satellite layers earn their keep. Large parts of central Idaho are roadless, so a lightning start can burn for days before anyone reports it. Thermal detections from VIIRS, MODIS and GOES will show the heat regardless of whether an incident record exists yet, though small or smouldering fires under cloud can still be missed.
Do I need a burn permit in Idaho?
Yes, during the closed fire season. Idaho law designates May 10 through October 20 as the closed season, and during it burning outside city limits without a permit from the local protective district fire warden is unlawful. Campfires are exempt unless prohibited during critical fire danger. The director of lands can extend the closed season when conditions stay dangerous, and has done so.
Can I track Idaho and Montana fires together?
Yes. The national view shows every state at once, which is useful along the Bitterroot Divide where the same coordinating group manages fires on both sides of the state line. You can also filter to a single state, or use the fires-near-me view, which works on distance in miles and ignores state boundaries entirely.
