Boise, Idaho – Mountain travel across central Idaho is expected to remain hazardous through Wednesday evening as steady snowfall and gusty winds continue to affect higher elevations and surrounding valleys.
According to the National Weather Service in Boise, a Winter Weather Advisory remains in effect for the Boise Mountains and the West Central Mountains through late Wednesday night. Valley locations could see 3 to 7 inches of snow, while areas above 6,000 feet may pick up between 10 and 20 inches before conditions improve. Wind gusts up to 35 mph are expected to cause localized blowing and drifting snow, further reducing visibility on exposed roadways.
Communities including Prairie, Pine, Warm Lake, Cascade, McCall, Ola, and Bear are likely to experience snow-covered roads, especially on mountain highways and secondary routes. Travel through higher terrain could become very difficult as snowfall accumulates throughout the day and evening, with plowing crews challenged by drifting snow in open areas.
Drivers heading into or out of mountain recreation areas should prepare for rapidly changing conditions. Slick pavement, sudden visibility drops, and drifting snow could develop quickly, particularly near mountain passes and forested roadways.
Officials urge motorists to slow down, allow extra stopping distance, and avoid unnecessary travel until conditions improve later tonight. Travelers should monitor Idaho 511 for updated road conditions, as advisories remain in effect through Wednesday evening and may be adjusted if snowfall persists.
