Windshield wipers are working nonstop across western Washington this morning as another Pacific storm system drenches the region. The steady hum of rain on rooftops and a faint mist rising from Puget Sound signal what forecasters call a prolonged wet stretch — one capable of producing localized flooding by Thursday.
According to the National Weather Service in Seattle, a Flood Watch remains in effect through Friday afternoon, covering King, Snohomish, Pierce, and surrounding counties. The agency warns that 2–4 inches of rain could fall through midweek, with totals higher in the foothills and Cascade slopes.
Meteorologists say urban flooding and rising rivers are the main concerns as soils saturate and runoff increases. Areas along the Snoqualmie, Stillaguamish, and Skagit Rivers could see levels nearing or exceeding minor flood stage by Thursday. Roads prone to poor drainage may also flood quickly, especially during the heaviest bursts of rain.
Commuters should plan for slick highways, standing water, and reduced visibility, particularly along I-5, Highway 99, and SR 520. Rain chances remain near 100% through Thursday, easing slightly Friday before another wet pattern approaches the weekend.
