Mount Rainier, Washington – Heavy snow is already piling up across the Washington Cascades tonight, and a multi-day mountain storm could bury higher elevations under up to four feet of snow by Friday morning.
According to the National Weather Service in Seattle, a Winter Storm Warning remains in effect until 5 a.m. Tuesday for the Cascades of Whatcom, Skagit, Snohomish, and northern King counties, including Mount Baker and Stevens Pass. Snow totals of 12 to 18 inches are expected with wind gusts up to 35 mph, creating snow-covered roads and sharply reduced visibility in higher terrain.
Farther south, a Winter Weather Advisory runs from 5 a.m. Monday through 5 p.m. Tuesday across the Cascades of southern King, Pierce, and Lewis counties, including Mount Rainier, Crystal Mountain, and Snoqualmie Pass. These areas could see 6 to 10 inches of snow with gusts up to 35 mph before a stronger system arrives.
Forecasters say the next storm could intensify late Tuesday night and continue through Friday morning, with 2 to 4 feet of snow possible across the Cascades and Olympic Mountains, including Hurricane Ridge. Winds could reach 45 mph Wednesday, leading to blowing snow, limited visibility, and possible temporary road closures.
Lower elevations near Snoqualmie Pass could briefly change to rain late Wednesday as snow levels rise before dropping again Thursday.
Travel through mountain passes may become difficult or impossible at times this week. Drivers are urged to carry chains, emergency supplies, and check Washington road conditions through the state’s transportation website before heading into the mountains. Additional warnings may be issued as the storm evolves.
