Seattle, WA – A major winter storm is set to impact mountain travel east and north of Seattle after the National Weather Service issued a Winter Storm Warning Monday afternoon for large portions of the Washington Cascades.
According to the National Weather Service in Seattle, the warning is in effect from 4 p.m. Tuesday through 10 p.m. PST Wednesday, with 10 to 18 inches of snow expected at Stevens Pass. Even higher snowfall totals are possible on peaks north of the pass, including areas near Mount Baker.
The warning covers the Cascades of Snohomish and Northern King counties, as well as the Cascades of Whatcom and Skagit counties, regions frequently traveled by commuters, freight traffic, and recreational travelers. Winds in the mountain passes could gust up to 35 mph, creating blowing snow and periods of sharply reduced visibility.
Forecasters say travel could become very difficult, especially during heavier snowfall Tuesday night and throughout the day Wednesday. Snow-covered roadways, drifting snow, and low visibility may make conditions hazardous or impassable at times.
The alert was issued at 1:55 p.m. Monday, upgrading an earlier winter storm watch as confidence increased in both snowfall totals and travel impacts. Officials warn that gusty winds combined with heavy snow could also lead to falling tree branches and isolated power outages in mountain communities.
Drivers planning to cross Stevens Pass or travel through the northern Cascades are urged to reconsider nonessential trips. Those who must travel should carry emergency supplies, including food, water, and a flashlight, in case of extended delays or closures.
The Washington State Department of Transportation recommends checking pass conditions frequently and preparing for sudden changes as the storm intensifies.
