Montana is facing a severe winter storm that is expected to deliver up to 2 feet of snow across higher elevations and up to 8-12 inches in lower mountain valleys through Wednesday. The National Weather Service (NWS) has issued a winter storm warning for large portions of western and central Montana, including areas near Missoula, Helena, and Bozeman. Travellers are being warned of dangerous conditions, with whiteout visibility, icy roads, and strong winds that could create drifting snow and travel delays.
The storm system, which began impacting the region late Monday, is drawing moisture from a powerful Arctic front. Meteorologists predict that the heaviest snowfall will occur between Monday night and Tuesday afternoon, with snowfall rates potentially exceeding 1 inch per hour. Areas above 5,000 feet, such as the Bitterroot Range and the Continental Divide, could see localized accumulations of up to 24 inches. Winds gusting up to 40 mph are expected to cause blowing snow, reducing visibility to near zero in some locations.
Key Areas of Impact:
Major highways, including portions of Interstate 90, Highway 12, and US Route 93, are likely to be severely affected by snow accumulation and slick conditions. The Montana Department of Transportation (MDT) has deployed plough crews and deicing operations, but drivers are advised to carry winter emergency kits and chains if travelling in affected areas.
Regional Concerns:
Lower elevations, including cities like Missoula and Kalispell, are forecasted to receive between 4 to 8 inches of snow. Meanwhile, eastern Montana could experience lower snow totals but bitter cold temperatures and gusty winds, creating wind chills as low as -20°F in some areas.
Authorities are urging residents to stay off the roads unless travel is essential. Those living in rural or isolated areas should be prepared for possible power outages, as heavy snow and ice buildup could affect power lines.
The NWS recommends monitoring local updates, and MDT advises checking road conditions frequently via their online travel services.
