Washington wakes to gray skies and steady rain across Seattle this early Sunday morning, the air cool and heavy with moisture. Roadways glisten before dawn as drivers navigate puddles and slick pavement—an early sign of a wetter, more dangerous pattern moving in.
According to the National Weather Service in Seattle, a Flood Watch remains in effect from late Sunday night through Friday afternoon as an atmospheric river pushes deep Pacific moisture into the region. The system is expected to bring 2 to 4 inches of rain across western Washington, with localized higher totals in the Olympic and Cascade foothills.
Officials warn that excessive runoff could cause flooding of rivers, creeks, and low-lying roads, especially along I-5, Highway 2, and the Snohomish and Skagit River valleys. Urban flooding and clogged drains may worsen travel conditions through the week, particularly during morning commutes.
By Monday, rain intensifies with gusts up to 30 mph, making travel hazardous for commuters and freight haulers alike. Flood-prone neighborhoods in King, Snohomish, and Pierce Counties are urged to prepare now—clear drains, secure outdoor items, and avoid parking near streams or underpasses.
Meteorologists say the wet stretch could extend through Friday, with only brief breaks midweek. Saturated soils heighten the risk of landslides and debris flows, especially near burn scars east of Puget Sound.
While the Pacific Northwest faces flooding, forecasters also track a major winter pattern expected to grip the Great Lakes and Midwest between Dec. 11–17, bringing snow, wind, and the season’s coldest air.
