(Riverton, Wyo.) – The National Weather Service Forecast Office said Wednesday afternoon that “a complex winter storm moving into the region is already dropping snow across the far west, heavy at times, with snow predicted through through Thursday night, tapering off into Friday. Snow is moving into southern Wyoming and to areas east of the Divide this afternoon with off and on snow also possible through early Friday morning.

“Even as the storm is on our doorstep, a lot of uncertainty remains as models struggle with the details of timing, movement, and the strength of certain features,” the NWS forecasters said. “However, the models maintain a lot of snow in the mountains, and the impact of this snow will be enhanced by strong winds causing widespread blowing and drifting snow today and tonight. The combination of the heaviest snow and strongest wind tonight through Thursday in the mountains could have a large impact on travel and potentially on avalanche conditions.

“The Bridger-Teton Avalanche center currently has avalanche danger as HIGH across all of their forecast areas. In addition, WYDOT plans on closing Teton Pass at 3 a.m. January 30 (tonight/early Thursday morning) for avalanche control. The road could close sooner if conditons continue to deteriorate as rapidly as they are so please keep a close eye on the road conditions if you must travel over the pass between tonight and Friday. 

Roads and passes across western and central Wyoming could have restricted travel or could close during this event.
