Spokane, Washington – Mountain travelers across the Idaho Panhandle are facing dangerous winter driving conditions as a Winter Weather Advisory remains active through Friday morning, impacting higher elevations of the Central Panhandle Mountains.
The advisory, issued by the National Weather Service in Spokane, warns that steady snowfall above 3,000 feet could result in 4 to 9 inches of accumulation, with the heaviest totals expected at exposed mountain passes. Snow is forecast to continue until around 10 a.m. PST Friday, creating hazardous conditions for overnight and early morning travel.
Areas Most Affected by the Winter Weather Advisory
The advisory covers several heavily traveled mountain routes that connect northern Idaho and western Montana, including:
- Lookout Pass
- Mullan Pass
- Dobson Pass
These routes are especially vulnerable due to elevation and terrain. Officials expect snow-covered and slick roadways, particularly during overnight hours when temperatures drop and snow compacts quickly.
Snowfall and Wind Impact on Travel
Forecasters say snowfall will be accompanied by wind gusts reaching up to 30 mph, which may lead to blowing and drifting snow in open areas and along ridgelines. While winds are not expected to reach damaging levels, even moderate gusts can significantly reduce visibility in mountain corridors.
Drivers may encounter:
- Reduced visibility
- Compacted snow and icy pavement
- Sudden changes in conditions with elevation
Weather officials caution that conditions can deteriorate rapidly, especially during heavier snow bands.
Travel Risks and Safety Concerns
Mountain travel during winter advisories often comes with heightened risk, particularly for drivers unfamiliar with snow-covered terrain. Slick roads and drifting snow can make braking and steering difficult, increasing the likelihood of spinouts or road closures.
Authorities strongly urge motorists to:
- Reduce speeds
- Allow extra travel time
- Maintain safe following distances
- Carry winter emergency supplies
Vehicles traveling through higher elevations should be equipped with winter tires or chains, depending on local requirements.
Elevation Plays a Major Role in Snow Accumulation
Officials emphasize that snowfall amounts will vary widely based on elevation. While nearby valleys may see lighter snow or rain-snow mixes, mountain passes above 3,000 feet are expected to receive the most significant accumulation, making them especially hazardous.
This sharp contrast can catch travelers off guard, particularly those starting in lower elevations where road conditions may initially appear manageable.
Checking Road Conditions Before You Travel
Travelers are encouraged to monitor conditions closely before heading out. The most up-to-date information on Idaho road conditions is available by calling 511 or visiting 511.idaho.gov, which provides real-time updates on closures, traction requirements, and weather impacts.
What to Expect Through Friday Morning
Snowfall is expected to gradually taper off later Friday morning, but lingering slick conditions may persist even after precipitation ends. Crews will continue snow removal operations, but drivers should remain cautious until roads are fully cleared.
Winter weather advisories serve as a reminder that mountain travel can become dangerous quickly this time of year. Staying informed and prepared can make a critical difference.
