Missoula, MT – A prolonged winter storm could bring significant travel disruptions to Missoula and surrounding western Montana beginning Wednesday night, with heavy mountain snow, gusty winds, and hazardous road conditions expected through late Friday night.
According to the National Weather Service in Missoula, a Winter Storm Watch is in effect for the Bitterroot and Sapphire mountains and the southern Clearwater Mountains. Snow is expected to develop late Wednesday night and continue through Friday, with impacts ranging from moderate to potentially major in higher elevations.
Valley locations could see 1 to 5 inches of snow during the storm, while mountain areas may receive up to 24 inches, particularly over higher passes. Winds could gust as high as 45 mph, creating blowing and drifting snow and sharply reducing visibility.
The most dangerous conditions are expected along major travel corridors, including U.S. Highway 93 from Sula to Lost Trail Pass, Highway 12 from Lowell to Lolo Pass, and surrounding mountain routes near Elk City, Dixie, and Lolo Pass. Forecasters warn that travel could become very difficult or impossible at times, especially during periods of heavy snowfall.
The National Weather Service notes that moderate impacts could include disruptions to normal activities and hazardous driving conditions, while major impacts could lead to widespread closures and infrastructure disruptions. Gusty winds may also bring down tree branches, increasing the risk of power outages.
Drivers are urged to use extreme caution, carry winter survival supplies, and consider postponing non-essential travel through mountain passes during the storm window. The hazardous conditions could impact both the Thursday morning and evening commutes.
Residents are encouraged to monitor forecast updates closely, as watches may be upgraded to warnings if confidence increases.
