Seattle, WA – Sunshine holds for one more day, but Washington residents should brace for a wet shift heading into the weekend. The National Weather Service warns that light rain could begin late Friday, growing steadier Saturday and lingering into early next week. Drivers, especially along I-5, should plan for slick pavement and slower travel times by Saturday night.
According to forecasters, Seattle will see highs in the upper 60s through Friday before clouds build and rain chances increase to 30% by Saturday night. Sunday carries the greatest potential for widespread showers across King County, with highs near 70 but persistent damp conditions. The unsettled stretch marks the first real taste of fall after a dry, mild September.
Areas from Tacoma to Everett could experience delays on major roads, ferries, and at Seattle-Tacoma International Airport as showers arrive. Commuters should allow extra time for travel, check road conditions, and keep headlights on during wet hours. For those heading outdoors, Saturday morning looks drier, with increasing rain chances later in the day.
By Monday, cooler air filters into the region, bringing highs only in the low to mid-60s. Early October continues the wet pattern, with showers and cloudy skies dominating through at least midweek. While no major flooding or wind hazards are expected, residents should prepare for consecutive days of damp weather and limited sunshine.
More updates are likely as the weekend system develops, with advisories possible if rainfall intensifies.
