Howell Fire, March 2024 Osage

Out · last detection 5 Apr 2024, 19:17 UTC

The fire started on 29 March 2024 in Osage, United States, and satellites saw it burning for 8 days. United States agencies (MTBS / NIFC) mapped an official burnt perimeter of 1,999 hectares, spread across a single county.

It is the 70th largest in Oklahoma since 2016 (of 284 with a page). Number 151 in United States in 2024, of 371.

It had gone 4 days without rain (1 mm or more) when it started. Rain came after the fire: 12.2 mm on 6 Apr.

This area had burned before

100% of the perimeter overlaps earlier fires recorded since 2016: 1,994 ha in 2018, 1,443 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 1,994 ha that had burned before.

Frequently asked questions

How long did the Howell fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 29 March 2024 to 5 April 2024 (8 days). The perimeter dates it from 5 April 2024 to 5 April 2024.
How much area did it burn?
The official perimeter published by United States agencies (MTBS / NIFC) is 1,999 hectares (20.0 km²). Other tallies, such as daily incident reports, may give slightly different figures.
Which counties burned?
The fire only entered Osage (1,999 ha, 0.3 %).
What was the weather like?
During the fire the temperature reached 24.9 °C, humidity dropped to 22 % and gusts hit 58 km/h. The fire danger index (FWI) reached 12, 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.

Where to verify it

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

Emergency number: 911

Satellite cross-check

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.

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.
