Horse Fire (WYBTF)

Wildfire Status:

The Horse Fire, reported on June 13, 2025, is currently active in the Bridger-Teton National Forest, approximately 10 miles west of Merna, Wyoming. This lightning-caused wildfire has burned through heavy downed timber and slash, spreading across an area of 2,797 acres. As of the latest update, fire containment efforts have successfully contained 70% of the fire's perimeter. The incident is under the command of Eric Neiswanger and Pepe Contreras, with a total of 70 personnel actively engaged in firefighting efforts.

Current weather conditions present both challenges and opportunities for firefighting efforts. A chance for showers and thunderstorms is expected, particularly between 1:00 PM and 4:00 PM, with gusty winds from the west-southwest at speeds of 10 to 15 mph, potentially gusting up to 30 mph. These conditions could lead to increased fire behavior, including group torching and spotting. However, the anticipated rain could also aid firefighting efforts by lowering temperatures and increasing humidity levels. Looking ahead, a warming and drying trend is expected to follow, which may lead to increased fire activity.

In addition to the firefighting efforts, certain areas within the Big Piney Ranger District have been subject to road and trail closures to ensure public safety. Residents and visitors are encouraged to monitor air quality and stay informed about the evolving fire situation through official channels.
