Cheyenne, WY – Critical fire weather conditions are developing this afternoon across southeast Wyoming, where strong winds and extremely dry air could allow fires to ignite and spread within minutes, especially along major travel corridors.
According to the National Weather Service in Cheyenne, humidity levels are expected to drop as low as 5% to 8% east of the Laramie Range, while southwest wind gusts reach 20 to 30 mph between 11 a.m. and 7 p.m. Monday. The highest risk zone includes Cheyenne, Laramie, Torrington, Wheatland, and areas along Interstate 25.
The combination of dry grasses, low humidity, and gusty winds creates conditions where any spark—whether from vehicles, equipment, or discarded cigarettes—can rapidly become uncontrollable. Strongest winds are expected along I-25 and nearby open plains, increasing the risk for fast-moving grass fires that could impact travel visibility and road safety.
Outdoor burning is strongly discouraged. Residents should secure loose items, avoid parking on dry grass, and delay any activity that could produce sparks. Emergency officials warn that response times can be challenged when fires spread quickly under these conditions.
The elevated fire risk will persist through early evening before winds gradually weaken after sunset. Additional updates are expected if warnings expand or conditions worsen.
