Washington – Rain is already spreading across Seattle this afternoon, turning streets slick and slowing traffic along I-5 and Highway 99 as steady showers fill in. Visibility drops at times, and puddles are forming on low-lying roads, signaling a damp stretch that will linger into early next week.
According to the National Weather Service, rain becomes widespread today with a 90% chance of precipitation and totals between a quarter and half an inch possible. Showers taper briefly later, but additional rounds return Sunday night and continue into Monday with another 40% chance of rain.
Across King County, including Bellevue, Shoreline, and Tacoma, drivers should expect consistent wet pavement and slower travel speeds through Sunday evening. Plan extra time, especially during heavier bursts that reduce visibility. Side streets and shaded areas may stay slick longer, particularly after sunset.
Temperatures remain cool, with highs in the mid-50s today and Monday, then dropping into the upper 40s by Tuesday as rain becomes steadier again. That cooler air keeps the pattern unsettled, with clouds dominating much of the skyline. Commuters should keep rain gear handy and allow for longer drive times into early Monday.
Conditions improve only slightly midweek, with partial clearing possible but lingering showers still in play. A more noticeable warming trend may arrive later next week.
