Seattle weather took a perilous turn on March 11, 2026, when a powerful windstorm swept through Western Washington, leading to overwhelming gusts of over 60 mph. This atmospheric river has resulted in tragic consequences and significant disruption across the region.
A somber note was struck when authorities reported one fatality following a large tree falling onto a vehicle east of Monroe at approximately 8:20 p.m. Firefighters from Snohomish Regional Fire & Rescue responded promptly, urging motorists and residents to avoid the affected area near Old Owen and Florence Acres roads.
Severe Wind Impacting Seattle Weather
As the storm developed, wind gusts reached up to 105 mph at Chinook Pass, with record-breaking speeds of 126 mph in the Alpental Summit area by Snoqualmie Pass. Throughout the Seattle metropolitan area, gusts over 45 mph were registered, causing widespread power outages. At least 120,000 residents across Western Washington found themselves without electricity due to the severe weather conditions.
In Grays Harbor County, the sustained winds arrived around noon, reporting winds exceeding 30 mph and gusts surpassing 60 mph. The Grays Harbor PUD reported that over 45,000 customers lost power amidst this unrelenting weather turmoil. Seattle City Light, alongside Snohomish County PUD, reported thousands more were left in the dark, with crews working tirelessly to restore services.
Blizzard Conditions and Travel Warnings
Storm systems also brought heavy snow to the Cascades and Olympics, leading to hazardous travel conditions. Meteorologists estimate that 30 to 36 inches of snow could accumulate by Friday near Snoqualmie Pass. The National Weather Service issued a blizzard warning, effective until 5 a.m. on Friday, warning of low visibility and considerable snow accumulation.
“We’re seeing heavy snow in the Cascades, but it’s also very windy, so it’s creating almost white-out conditions,” said Anna Lindeman, a meteorologist with the National Weather Service in Seattle. Motorists were urged to avoid mountain travel where possible and to carry chains if travel was necessary.
Community Response and Safety Measures
In response to the situation, Seattle firefighters reported at least eight instances of downed power lines. The effects of the storm were felt throughout the region as more than 58,100 Puget Sound Energy customers, along with 11,600 in Snohomish County and 5,800 served by Seattle City Light, were also without power.
Despite the severity of the storm, utilities managed to quickly address many outages. Snohomish County PUD spokesperson Aaron Swaney noted that their system was holding up well under the strong winds and that most issues were being resolved swiftly.
For citizens in the area, the ongoing risk of additional flooding looms as smaller rivers, including the Skokomish River, may approach action stages over the coming days. However, no significant flooding was anticipated for King County at this time.
With temperatures expected to reach a high of 42 degrees, conditions will remain unsettled as snow continues to fall in the mountains. The community is encouraged to stay updated and exercise caution during this extreme Seattle weather.
What to Expect Ahead
As we move forward, residents should remain vigilant and prepared for possible after-effects from the storm. While the immediate danger from the windstorm may decrease, residual impacts, including power restoration and travel advisories, are likely to continue for several days.
