A Red Flag Warning has been issued by the National Weather Service for parts of the Bighorn Basin, Owl Creek, and South Bighorn Mountains until 7:00 PM MDT today, October 9, 2026, due to critical fire weather conditions including strong winds, low humidity, and warm temperatures.

A Red Flag Warning is in effect until 7:00 PM MDT today, October 9, 2026, impacting the North Bighorn Basin/Worland BLM, Cody Foothills, South Bighorn Basin/Worland BLM, South Bighorn Mountains, and Owl Creek Mountains. This warning has been issued by the National Weather Service in Riverton, Wyoming.

Residents in affected areas should be aware that critical fire weather conditions are occurring or will occur shortly. The affected counties include Big Horn, Hot Springs, Johnson, Park, and Washakie in North Central Wyoming, as well as Fremont and Natrona in Central Wyoming.

The National Weather Service reports that strong winds from the southwest, gusting up to 35 mph, combined with low humidity (8 to 13 percent) and unseasonably warm temperatures in the lower to mid-80s, could lead to erratic fire behavior. This combination of weather factors can contribute to extreme fire behavior.

A Red Flag Warning signifies that conditions are ripe for rapid wildfire spread. Community members are urged to exercise extreme caution and follow all fire safety guidelines. Any outdoor burning is highly discouraged due to the elevated risk.
