Riverton, Wyoming – Snow and strong winds are creating hazardous travel conditions across western Wyoming’s mountains Thursday, prompting a Winter Weather Advisory through late afternoon.
According to the National Weather Service in Riverton, the advisory remains in effect until 5 p.m. MST Thursday for the Wind River Mountains West and the Teton and Gros Ventre Mountains. Additional snowfall totals of 4 to 8 inches are expected, with wind gusts reaching up to 45 mph at higher elevations.
The combination of accumulating snow and gusty winds may significantly reduce visibility and create drifting snow, particularly along exposed ridgelines and mountain passes. The National Weather Service warns that travel could be difficult, especially over Teton Pass and Togwotee Pass, where winter driving conditions can change rapidly.
Snowfall has been ongoing overnight and is expected to persist through the afternoon hours before tapering off later Thursday. Motorists traveling through mountain corridors are urged to reduce speed, allow extra travel time, and be prepared for rapidly deteriorating road conditions.
Wyoming Department of Transportation officials recommend checking the latest road conditions before departure. Real-time updates are available at wyoroad.info, including pass conditions and closures.

Winter weather advisories are issued when conditions are expected to cause significant inconveniences and may become hazardous if caution is not exercised. Those planning mountain travel Thursday should monitor weather updates closely and consider delaying trips if conditions worsen.
