Stanley, Idaho – Snow-covered roads and slick travel conditions are already affecting central Idaho, and forecasters say another, more impactful round of winter weather is expected to hit west central Idaho by midweek, bringing heavy snow and blowing conditions to the McCall region.
A Winter Weather Advisory remains in effect across several mountain zones, with hazardous travel expected through Wednesday as multiple systems move across the state.
Snow Continues Across Central Idaho Mountain Regions
According to the National Weather Service in Pocatello, light to moderate snow is continuing through mid-afternoon across the Sawtooth and Stanley Basin, Sun Valley region, Big Hole Mountains, and Big Lost Highlands.
Forecasters say an additional 2 to 5 inches of snow is expected before conditions gradually improve later today. Locally higher totals are possible near mountain passes, where snow accumulation tends to increase rapidly.
The snowfall has already led to slick and snow-packed roads during the morning commute in and around Stanley, Ketchum, Galena Summit, and Copper Basin, with visibility occasionally reduced during heavier snow bursts.
Travel Impacts Along Highway 75 and Sawtooth Valley
Roads through the Sawtooth Valley and along Highway 75 may remain slick into the early afternoon, especially on shaded stretches and higher elevations where snow and ice linger longer.
Transportation officials are urging drivers to:
- Reduce speeds
- Increase following distance
- Check road conditions before traveling, particularly for mountain routes
Motorists are encouraged to monitor Idaho 511 for real-time updates on road conditions, closures, and chain requirements.
Another Winter Weather Advisory Targets West Central Idaho
Attention now turns to west central Idaho, where another Winter Weather Advisory has been issued for the McCall, Cascade, Warm Lake, and Bear areas.
According to the National Weather Service in Boise, snow is expected to develop late Tuesday night and continue through Wednesday afternoon, bringing 5 to 9 inches of accumulation to the region.
Forecasters also warn that wind gusts up to 35 mph could accompany the snowfall, leading to blowing and drifting snow. These conditions may significantly reduce visibility at times, especially in open areas and along higher-elevation roadways.
Blowing Snow Could Worsen Midweek Travel Conditions
The combination of fresh snowfall and strong winds is expected to create hazardous travel conditions across west central Idaho on Wednesday.
Drivers traveling between communities such as McCall and Cascade or along secondary mountain roads should be prepared for:
- Rapidly changing visibility
- Drifting snow across roadways
- Snow-covered and icy surfaces
Officials caution that conditions may deteriorate quickly during heavier snow bands, even if roads appear manageable earlier in the day.
Mountain Travel Hazards Likely Through Midweek
With multiple weather systems affecting Idaho, mountain travel remains hazardous through at least midweek, and meteorologists note that additional advisories or extensions are possible if snowfall totals increase or winds strengthen.
Residents and travelers are advised to:
- Carry winter emergency gear, including blankets, food, and water
- Allow extra travel time
- Stay informed on updated forecasts and advisories
Those with flexible travel plans may want to consider postponing non-essential trips through mountain passes until conditions improve.
Conclusion
Snowy and windy conditions are creating dangerous travel conditions across central and west central Idaho, with the McCall area potentially seeing up to 9 inches of snow by Wednesday. As winter weather advisories remain in effect, officials urge drivers to stay cautious, plan ahead, and remain alert for changing conditions throughout the week.
