Cheyenne, Wyoming – Strong winds and critical fire weather are creating dangerous travel and fire conditions across southeastern Wyoming and western Nebraska through Monday night.
According to the National Weather Service in Cheyenne, a High Wind Warning has been expanded to include the Interstate 80 Summit, effective until 11 p.m. Monday. Wind gusts are expected to reach 70 mph, with isolated gusts up to 80 mph, particularly along wind-prone corridors near and east of the Laramie Range.
The Foothills remain under a High Wind Watch through late Monday night, while a Red Flag Warning continues until 5 p.m. Monday for southeastern Wyoming and western Nebraska, including areas near Cheyenne, Scottsbluff, Alliance, and Chadron.
Forecasters say the most severe conditions are expected east of the Laramie Range, where very strong winds combined with dry fuels could allow any fires that start to spread rapidly. The National Weather Service emphasized that even small sparks from vehicles, equipment, or outdoor burning could quickly turn into fast-moving fires.
Travel along I-80 and I-25 may become hazardous, especially for high-profile vehicles such as semis, campers, and trailers. Sudden gusts could cause difficult driving conditions, reduced vehicle control, and temporary road impacts during peak wind periods from Sunday night into Monday evening.
Emergency officials urge residents and travelers to secure loose objects, avoid outdoor burning, and use extreme caution if driving through affected areas. Motorists should check road conditions before traveling and be prepared for sudden crosswinds.
The combination of high winds and fire danger may also affect commuters and students traveling along major highway corridors Monday.
