'REALLY challenging' conditions for Washington passes next few days, WSDOT warns

A significant winter storm could force the closure of Snoqualmie Pass, Stevens Pass and other mountain roads in Washington.

SNOQUALMIE PASS, Wash. — Washington State Department of Transportation is warning drivers of difficult conditions expected in the mountain passes starting Wednesday.

Winter storm warnings are in place across the Northwest ahead of an incoming storm. Widespread snow is expected from the Cascades to the Northern Rockies.

The forecast calls for the possibility of several feet of snow in the Washington mountain passes through Thursday. WSDOT said the storm could dump a couple of inches of snow an hour, on top of snow that has already fallen.

“While our crews continue to plow 24/7, with that level of snow, no amount of plowing would keep the pass clear,” WSDOT tweeted. “As soon as we plow an area, a bunch more snow covers it until we can come back around.”

The snow comes at a time when Snoqualmie Pass has already seen its highest snowfall amount in 20 years. As of Monday, 236 inches had already fallen along I-90.

Drivers have already faced several closures of the mountain passes this winter, including Snoqualmie Pass along I-90 and Stevens Pass on Highway 2. The closures cut off the primary driving routes between Spokane and Seattle.

WSDOT warns conditions could deteriorate later this week with a warm-up and rain in the forecast. That is expected to create significant avalanche danger, which could force the closure of the passes.

If you do travel over the mountains in the next few days, WSDOT said, “it’s going to be REALLY challenging.” The agency is asking drivers to be prepared for delays and closures and extremely slow going.
