Seattle, Washington – A broad Pacific Northwest rain pattern is set to intensify by Wednesday morning, bringing repeated rounds of rain and slower travel across Washington through the end of the workweek.
According to the National Weather Service Climate Prediction Center, Washington is in a high-confidence zone for above-average precipitation from Wednesday through Saturday, with totals expected to run 30 to 60 percent higher than normal. Temperatures are also trending above seasonal levels, bringing a milder and persistently damp stretch across much of the state.
Seattle, Tacoma, and Olympia are expected to see multiple waves of rainfall, increasing the risk of standing water on major corridors including I-5 and I-90. In western Washington, including Everett and Bellingham, steadier rain could reduce visibility and overwhelm urban drainage systems during peak commute hours. Central areas such as Yakima may see periods of lighter but consistent rain, while eastern cities including Spokane could experience localized ponding and slick ճանապարհways.
Drivers should slow down on wet roads, avoid water-covered lanes, and allow extra time for travel. Residents are encouraged to clear storm drains and monitor areas prone to poor drainage.
This wet pattern is expected to continue through Saturday night, with additional advisories likely as rainfall totals and timing become more defined.
