A late-season winter storm is set to impact parts of Montana and Washington, bringing hazardous conditions and significant snowfall. The National Weather Service (NWS) has issued warnings for both states, with forecasts indicating accumulations of up to 6 inches in certain mountainous areas.
Heavy Snow Alert: 6 Inches Expected Across Two States
As spring travel and tourism pick up, late-season winter storms can create unexpected hazards. Areas in the Northern Rockies and Pacific Northwest are particularly vulnerable as popular destinations transition from winter sports to spring activities. The quick return of snow can impede travel and surprise visitors unprepared for severe weather.
Montana’s Winter Weather Advisory
- Advisories are focused on mountainous regions, including Gallatin and Madison County Mountains, and Glacier National Park.
- Expected snow accumulations range from 3 to 7 inches at higher elevations.
- Snowfall is projected to begin Saturday evening and last through Sunday.
- Wind gusts may reach up to 40 mph, reducing visibility on roads.
The peak impacts in southwest Montana are anticipated between 5 p.m. Saturday and 6 a.m. Sunday. Travelers should be prepared for slushy and slick roads, especially in mountain passes such as Targhee Pass and Raynolds Pass. In Glacier National Park, conditions are expected to worsen with additional snowfall of 2 to 6 inches above 5,000 feet.
Winter Weather Conditions in Washington
- Winter weather advisories span the Cascades and Olympic Mountains, impacting travel corridors including Stevens Pass and Snoqualmie Pass.
- Forecasters predict 4 to 6 inches of snow accumulation above 4,000 feet.
- Late Friday into Saturday morning may see moderate to heavy snow, increasing travel disruptions.
In western Washington, snow will be most significant between Whatcom and Lewis counties, expected to intensify during Friday and Saturday afternoons. Although warm ground temperatures may minimize accumulation on major roadways, travel on less maintained routes could face snow cover during heavier snow events.
Preparedness and Safety Recommendations
Officials in both states are advising residents and visitors to monitor weather forecasts closely. They should be prepared for winter-like conditions while traveling in mountainous areas. Drivers should exercise caution, reduce speeds, and verify road conditions before departing.
- Outdoor enthusiasts are encouraged to bring waterproof layers, thermal gear, and emergency supplies when heading into backcountry areas.
The winter storm is expected to weaken by late Sunday. However, forecasters caution that unsettled conditions may persist, with lingering showers and below-average temperatures. Proper preparation is key to staying safe in these changing weather patterns.
