How long did the Ochiltree fire last?

The official perimeter only gives the start date (22 February 2022). The end comes from the heat detections inside the perimeter: it burned until 22 February 2022 (1 day from 22 February 2022), the last day with detections before more than 10 days in a row without any, so it is approximate.

How much area did it burn?

The official perimeter published by United States agencies (MTBS / NIFC) is 447 hectares (4.5 km²). Other tallies, such as daily incident reports, may give slightly different figures.

Which counties burned?

The fire only entered Ochiltree (440 ha, 0.2 %).

What was the weather like?

During the fire the temperature reached 8.4 °C, humidity dropped to 38 % and gusts hit 44 km/h. The fire danger index (FWI) reached 20, class Moderate.

Where does this data come from?

From the official burnt perimeter of United States agencies (MTBS / NIFC, public domain), NASA FIRMS VIIRS hotspots and the administrative boundaries of United States. It is not an official report.

Ochiltree fire, February 2022 Ochiltree

Out · last detection 22 Feb 2022, 19:10 UTC

The fire started on 22 February 2022 in Ochiltree, United States, and satellites saw it burning for 1 day. United States agencies (MTBS / NIFC) mapped an official burnt perimeter of 447 hectares, spread across a single county.

It is the 304th largest in Texas since 2016 (of 327 with a page). Number 473 in United States in 2022, of 493.

The power measured by the satellite is low (7.3 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Does something look wrong on this page?

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.

How we know this

Perimeter: MTBS (US Geological Survey and US Forest Service), official.
The official perimeter has no end date: the end is the last day with VIIRS detections inside the perimeter before a gap of more than 10 days (150 days at most), so it is approximate. 2 Suomi-NPP VIIRS detections on those dates.
We have not matched this page with any official record.
Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.

Where this data comes from

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.
