Cheyenne, Wyoming – Fire crews across southeast Wyoming and the Nebraska Panhandle are on alert as critical fire conditions ramp up by noon Sunday, with fast-moving flames capable of spreading within minutes under dry, windy conditions.
According to the National Weather Service in Cheyenne, a Red Flag Warning takes effect at 12 p.m. Sunday and continues until 8 p.m. Monday, replacing an earlier watch. Gusty winds between 15 and 20 mph, with gusts reaching 35 mph, combined with humidity levels as low as 8 percent, are expected to create explosive fire growth potential across multiple zones.
In Laramie County, including Cheyenne, open fields and grasslands could ignite fires, especially along Interstate 80 where crosswinds may also impact travel. Farther east in Scotts Bluff County, including Scottsbluff and Gering, dry fuels near the North Platte River Basin increase the likelihood of fast-spreading grassfires.
Goshen County communities like Wheatland and Torrington should prepare for reduced humidity recovery overnight Sunday, meaning fire danger will persist even after sunset. In Niobrara and Converse counties, including Lusk, the combination of warm temperatures and dry air could stress firefighting resources if multiple ignitions occur.
Officials urge residents to avoid outdoor burning, secure trailer chains, and avoid parking vehicles on dry grass. Even small sparks from equipment or cigarettes could trigger large fires under these conditions.
The warning remains in effect through Monday evening, and additional alerts may be issued if conditions worsen or extend into early next week.
