Cheyenne, WY – The National Weather Service (NWS) in Cheyenne has issued High Wind Warnings for parts of southeast Wyoming, warning drivers and residents to brace for gusts up to 70 mph through Tuesday morning. The powerful winds are expected to make travel along Interstates 80 and 25 extremely hazardous, particularly for lightweight and high-profile vehicles.
The Incident: High Winds Expected Overnight Across Wyoming
According to the NWS forecast, the South Laramie Range and Foothills—including Interstate 80 between Cheyenne and Laramie and Interstate 25 near Bordeaux—will experience the strongest winds. Conditions will intensify Monday evening, with sustained speeds between 35 to 45 mph and gusts up to 70 mph, continuing until 11 a.m. Tuesday.
Another High Wind Warning is in effect for the North Snowy Range Foothills, affecting Arlington and Elk Mountain along I-80, where gusts up to 65 mph are expected from 5 p.m. Monday through 2 p.m. Tuesday.
“Winds will be strongest in the typical wind-prone corridors between Laramie and Rawlins, and Chugwater to Wheatland,” said meteorologists with the National Weather Service in Cheyenne.
Impact and Safety Hazards
The combination of strong crosswinds and gusty conditions poses a serious threat to truckers, campers, and high-profile vehicles, which may be at risk of rollovers or loss of control. Drivers are advised to delay travel if possible or exercise extreme caution when crossing elevated areas and mountain passes.
The NWS also cautioned that lightweight vehicles, especially trailers, RVs, and box trucks, could be blown off the road in exposed areas. Residents are being urged to secure loose outdoor objects, such as trash bins, decorations, and patio furniture, to prevent them from becoming airborne and causing damage.
Statements from Officials and Weather Experts
Weather officials emphasized that wind speeds exceeding 60 mph are not uncommon in southeastern Wyoming during autumn, but this particular event could bring sustained, damaging winds over several hours.
“These gusts are strong enough to create dangerous driving conditions and minor structural damage,” said an NWS Cheyenne forecaster. “We’re urging the public to prepare for prolonged high winds overnight.”
The Wyoming Department of Transportation (WYDOT) has also issued travel advisories for both Interstate 80 and Interstate 25, warning of strong crosswinds and reduced visibility due to blowing dust and debris.
Background Context: Why Wyoming Is Prone to Extreme Winds
Wyoming’s geography and elevation make it particularly susceptible to high wind events during the fall and winter months. The Rocky Mountain Front Range often channels air masses through narrow passes, amplifying wind speeds.
The I-80 corridor, which stretches from Cheyenne to Rawlins, is one of the most wind-prone stretches of interstate in the United States. WYDOT frequently issues warnings and even temporary closures for large vehicles during similar conditions.
Meteorologists explain that the combination of strong pressure gradients and mountain wave activity leads to intense gusts, especially during the transition between seasonal air masses.
Ongoing Developments and Next Steps
The High Wind Warnings remain in effect through Tuesday afternoon, with wind speeds expected to gradually decrease by late Tuesday evening. Drivers traveling across the southern part of the state are encouraged to check WYDOT road condition updates before departing and plan alternate routes if necessary.
Officials remind the public to avoid unnecessary travel overnight and to report any hazardous road conditions to local authorities.
“If you must drive, keep a firm grip on the wheel, reduce speed, and be aware of sudden gusts,” officials said. “Your safety comes first—especially when conditions change rapidly.”
Conclusion
With wind gusts reaching up to 70 mph, Wyoming residents and travelers should remain alert and take all necessary precautions. The National Weather Service and WYDOT continue to monitor conditions closely and urge the public to stay informed through official weather alerts and traffic updates.
