WASHINGTON — Winter weather advisories have been expanded to the western slopes of the Cascades, taking effect at 5 p.m. Tuesday and running until 5 p.m. Wednesday. Snowfall totals of 3 to 12 inches are expected, with the heaviest amounts above 4,000 feet. Gusts up to 35 mph on the east slopes and slick mountain roads could make travel over the passes difficult through Wednesday evening.
Advisories Cover the Cascades From Whatcom and Skagit Counties to Pierce and Lewis Counties
The advisories stretch across the Cascades from Whatcom and Skagit counties south to Pierce and Lewis counties. They also include the upper east slopes along with western Chelan and Okanogan counties, covering a large portion of the mountain corridor across the state.
Major routes inside the advisory area include Washington Pass and Loup Loup Pass in the north, Stevens Pass along U.S. Highway 2, and Snoqualmie Pass along Interstate 90. Chinook Pass and White Pass farther south are also included.
Heaviest Snow of 6 to 12 Inches Expected in Pierce and Lewis County Cascades
The Cascades of Pierce and Lewis counties are expected to see the highest totals, with 6 to 12 inches of snow possible. This area includes routes near Chinook Pass along State Route 410 and White Pass along U.S. Highway 12.
Elsewhere in the advisory area, totals of 3 to 12 inches are expected, with the deepest snow falling above 4,000 feet. Lower elevations will likely see smaller amounts as temperatures stay closer to the rain and snow line.
Snoqualmie Pass Could See 1 to 3 Inches With Rain Mixing In
Snoqualmie Pass is expected to pick up a lighter 1 to 3 inches of snow, with rain mixing in at times. The mix of rain and snow could still create slushy and slippery stretches along Interstate 90 through the pass.
On the east slopes, gusts up to 35 mph could cause blowing snow and reduced visibility in exposed areas. Drivers crossing from the west side to central Washington should be prepared for changing conditions along the way.
Slick Roads, Bridges, and Overpasses Could Slow Pass Travel Through Wednesday
Roads across the mountain passes could become slick through 5 p.m. Wednesday, especially on bridges and overpasses where ice tends to form first. Travelers heading over the passes should slow down and allow extra time to reach their destinations.
Carrying chains, warm clothing, water, and a fully charged phone is recommended for anyone driving through the Cascades during the advisory. Checking pass conditions before leaving can help avoid delays or closures.
