Seattle, Washington – Near-zero visibility and powerful wind gusts are hammering Washington’s mountains overnight, creating blizzard conditions that could make travel nearly impossible across key passes until early Thursday morning.
According to the National Weather Service in Seattle, a Blizzard Warning remains in effect until 5 a.m. Thursday for the Olympic Mountains and much of the Washington Cascades, including Snoqualmie Pass, Stevens Pass, and White Pass. Winds may gust between 60 and 65 mph while blowing snow reduces visibility to dangerous levels across higher terrain.
Conditions will transition into a prolonged winter storm beginning at 5 a.m. Thursday. A Winter Storm Warning will remain in place through 5 a.m. Saturday for the Cascades and Olympic Mountains, where forecasters expect between 1 and 3 feet of additional snowfall.
Heavy snow and wind-driven drifts may repeatedly bury roadways along Interstate 90 at Snoqualmie Pass and U.S. Highway 2 at Stevens Pass. Areas near Mount Rainier, Mount Baker, and Crystal Mountain could also see rapid accumulation that limits travel and increases avalanche concerns in steep terrain.
Hurricane Ridge and other high elevations in the Olympic Mountains may experience temporary road closures as wind gusts near 60 mph combine with heavy snowfall.
Officials urge travelers to postpone nonessential trips into the mountains. Drivers who must travel should carry emergency supplies including blankets, food, water, and a flashlight in case road closures leave vehicles stranded.
Heavy snow and strong winds are expected to continue through early Saturday across Washington’s mountain ranges, and additional weather alerts may be issued as the storm develops.
