First Big Snowstorm Of The Season Hits The Cascades

SEATTLE, WA — Steady snowfall will hammer the Cascades into Thursday evening, before tapering off into lighter showers Friday. The National Weather Service said periods of heavy snowfall, with levels dipping below 3,000 feet at times, will pack more accumulation than initially predicted.

In Snoqualmie Pass, which at first was expected to get just a couple inches, up to a foot of new snow may fall by Friday morning. Stevens Pass and White Pass will pick up between 18 and 24 inches, while Mount Rainier could see up to 5 feet.

According to the NWS, the heaviest snow will fall between now and Thursday night. The Washington State Department of Transportation advised drivers to avoid traveling in the mountain passes unless absolutely necessary.

Ski resorts posted videos and photos on social media as the storm rolled in Wednesday. Crystal Mountain, which opened limited runs after Thanksgiving, said the new accumulation should allow more lifts to open Friday.

In the lowlands, rain will continue into Friday morning, but the winds seen Wednesday should dissipate by Thursday. Forecasts show afternoon highs staying fairly uniform Thursday and Friday, in the high 40s to low 50s range for Seattle, Tacoma, Olympia, and North Bend.

For those who must take trips through the mountains, along Interstate 90, Highway 2, or Highway 12, Washington State Patrol put together an instructional video showing how to apply chains. Drivers should also plan for potential delays and make sure to pack emergency gear before heading out the door.
