Satellites first detected fire on 4 November 2026 in Owyhee, United States. It has been active for 8 days, with 35 heat detections and an area with fire of about 420 hectares rebuilt from them, spread across a single county.
The power measured by the satellite is low (29.6 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Estimated from hotspots: no perimeter has been published yet.
This is an estimate from the VIIRS pixels that saw fire. It will change when the perimeter is published.
From 4 Nov 2026 to today: still being detected.
Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.
First day with fire seen by the satellites or the perimeter.
No official record is matched to this page, so the alert time and the cause are not known here.
VIIRS detections at 375 m. Most intense hotspot: 30 MW.
There is no official record to compare with. Each hotspot is a pixel detected in one satellite pass, not a separate fire.
Total radiative power on 11 November 2026; hotspots that day: 25.
Fire radiative power (FRP) measures the energy the fire gives off when the satellite passes. Added up by day, it compares intensity, not area.
Fire Weather Index (Canadian system) computed by WorldFires for the day the fire started. Consecutive days without rain before: 2.
This is an index computed from weather model data, not a measurement of the fire nor an official warning. Danger warnings are issued by each country’s authority. Emergency number and official warnings
High of 15.9 °C and minimum humidity of 21% on 11 November 2026; gusts of 41 km/h on 8 November 2026.
These are model values for a cell of about 25 km, not from a weather station: they may differ from what was measured on the ground.

NIFC has not yet published the perimeter of this fire. For now the area is the one rebuilt from heat detections (about 14 hectares per pixel). When the perimeter arrives, this page picks it up on its own and keeps the same address.
Satellites detected fire on 11 Nov 2026, 21:20 UTC. Everything suggests it is still burning. Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
It had gone 2 days without rain (1 mm or more) when it started.
Area with fire inside each county, rebuilt from heat detections (about 14 hectares per VIIRS pixel). An estimate until NIFC publishes the official perimeter. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.
ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

It started with an FWI of 3.3, a minimum humidity of 54% and 2 days without rain. Fires in the area that started in weather like this since 2016: 1.
First rain (1 mm or more) after it ended: 1.4 mm on 9 Mar.
Fires in the area that started in similar weather: 1. With fewer than 15 we give no figures: they would be more noise than signal.
This is a bank of analogues: it shows what usually happens, not what will happen. With fewer than 15 twins we give no figures. How we calculate it
Drag the line to compare the same ground before the fire and after it.
If the day is cloudy, change the date: each satellite passes once a day. In false colour the burnt ground looks brown or red.

A satellite detection is not an official report. Final figures and the fire’s status are published by each country’s emergency service.

Satellite cross-check
This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.
The perimeter is official and in the public domain. For past years it comes from MTBS (Monitoring Trends in Burn Severity), run by the U.S. Geological Survey and the USDA Forest Service, which map it on Landsat and Sentinel-2 imagery. For the current and last year it comes from WFIGS at the National Interagency Fire Center (NIFC): incident perimeters mapped by fire crews, aircraft and imagery. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. County boundaries come from geoBoundaries ADM2 (Public Domain). The area per county is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from official figures.
