Seattle, Washington – A Winter Storm Warning remains in effect across the Washington Cascades as heavy snow and strong winds continue to create dangerous travel conditions through Thursday afternoon.
According to the National Weather Service in Seattle, additional snowfall of 2 to 19 inches is expected across the Cascades of Whatcom, Skagit, Snohomish, King, Pierce, and Lewis counties. Wind gusts may reach 40 miles per hour, producing blowing snow and sharply reduced visibility at times.
The warning remains in effect until 4 p.m. PST Thursday. Travel conditions may range from very difficult to nearly impossible, particularly during the Thursday morning commute. Snow and wind impacts are affecting major mountain routes and recreation areas, including Snoqualmie Pass, Stevens Pass, White Pass, Crystal Mountain, Mount Baker, Mount Rainier, Paradise, Greenwater, Ashford, and SR-18 at Tiger Mountain Summit.
Roads, bridges, and mountain passes are expected to be snow-covered and slick, with periods of poor visibility during heavier snowfall. Power outages are possible in higher elevations where heavy snow accumulates on trees and power lines.
The National Weather Service urges travelers to postpone non-essential travel through the Cascades. Those who must travel should carry emergency supplies, including food, water, and a flashlight, and be prepared for extended delays.
Conditions are expected to gradually improve late Thursday afternoon as snowfall tapers off, but lingering impacts may continue into Thursday evening.
