Boise, Idaho – Mountain travel across central Idaho remains hazardous as a significant winter weather system continues to impact the region through Wednesday evening. Steady snowfall combined with gusty winds is creating difficult driving conditions at higher elevations and in nearby 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. Snowfall totals are expected to vary widely depending on elevation, with the most intense accumulation occurring above 6,000 feet.
Snowfall Totals Expected Across Elevations
Forecasters report that valley locations may receive 3 to 7 inches of snow, while higher elevations could see significantly heavier totals. Areas above 6,000 feet are forecast to accumulate 10 to 20 inches of snow, with localized amounts potentially higher in favored terrain.
Strong winds accompanying the storm are expected to complicate conditions further. Wind gusts reaching up to 35 mph may cause blowing and drifting snow, reducing visibility and making already slick roadways even more dangerous.
Communities Likely to Be Impacted
Several mountain and valley communities are expected to experience hazardous conditions throughout the day and evening. Locations most likely to see snow-covered roads and reduced visibility include:
- Prairie
- Pine
- Warm Lake
- Cascade
- McCall
- Ola
- Bear
Mountain highways, forest roads, and secondary routes in these areas may become difficult or nearly impassable at times as snowfall continues to accumulate and winds redistribute snow across open stretches.
Travel Conditions in the Boise Mountains
Travel through higher terrain is expected to remain challenging, especially near mountain passes and exposed roadways. Plowing operations may struggle to keep roads clear due to drifting snow, particularly in open areas where wind speeds are highest.
Drivers heading toward mountain recreation areas should be aware that conditions can change rapidly. Clear roads can quickly become snow-packed or icy, and visibility may drop suddenly due to blowing snow. Even experienced winter drivers may find travel difficult during peak snowfall periods.
Safety Guidance for Motorists
Officials urge motorists to take extra precautions if travel is unavoidable. Drivers should slow down, maintain extra following distance, and be prepared for sudden stops or reduced visibility. Emergency supplies, including blankets, food, water, and traction devices, are strongly recommended for anyone traveling through mountainous areas.
Authorities also advise avoiding unnecessary travel until conditions improve later Wednesday night. Travelers are encouraged to check Idaho 511 for real-time road conditions, closures, and updates before heading out, as advisories may be extended if snowfall continues longer than expected.
What to Expect as Conditions Improve
Snowfall intensity is expected to gradually decrease later Wednesday night as the system moves east. However, lingering snow cover and icy conditions may persist into Thursday morning, particularly in shaded or higher-elevation areas.
Motorists should remain cautious even after snowfall tapers off, as overnight refreezing could lead to slick conditions during early morning hours.
Conclusion
The ongoing winter storm is bringing significant snowfall and strong winds to the Boise Mountains and surrounding regions, making travel hazardous through Wednesday evening. With up to 20 inches of snow possible at higher elevations, residents and travelers are urged to remain alert, monitor official updates, and delay travel when possible until conditions improve.
