Forecasters have issued an updated Winter Weather Advisory for the Cascades of Whatcom and Skagit Counties, as well as Western Okanogan County. Along the Cascade Crest and the highest elevations of Highway 20, heavy snow is expected to begin Wednesday at 4 p.m., bringing potentially severe travel conditions.
Snow is forecast to build across higher elevations as cold air meets moisture-heavy clouds. The most difficult travel periods are expected from Wednesday evening through Thursday morning, then again Thursday night. Drivers should remain ready for fast-changing traction near the crest and Washington Pass.
“Travel could be very difficult to impossible in spots.”
Residents above 4,000 feet are likely to face the heaviest accumulations, while valley communities will contend with slush, black ice, and slow snow removal. Power flickers may occur, but advance preparation can help reduce disruption. Officials encourage delaying nonessential travel and maintaining patience through the storm’s duration.
The advisory highlights the importance of patience, caution, and planning ahead. Safe choices and calm preparation are key to navigating the next several days of winter weather in the Cascades region.
