Seattle, WA – A soggy start to the week is brewing across western Washington as Seattle braces for heavy rain and isolated thunderstorms through early Monday. Drivers along I-5 and downtown arterials should prepare for slick roads, rising water in low-lying areas, and reduced visibility during commutes.
According to the National Weather Service in Seattle, steady rain begins Saturday afternoon and continues through at least Monday morning. Winds will increase Saturday night with gusts up to 20 mph. Between one-half and one inch of rain is expected by Sunday night, with higher totals possible in some neighborhoods.
Sunday may bring embedded thunderstorms after 11 a.m., pushing storm drains and gutters to their limit. City crews are urging residents to clear leaves from grates and monitor local flood-prone streets like Mercer and Rainier Ave. Those heading to pumpkin patches or outdoor markets should dress for wet, windy conditions and avoid low-lying roadways.
By Monday, showers will taper, but lingering moisture may still impact early morning travel. Conditions dry slightly into Tuesday, though another round of showers could return midweek. Temperatures will hold steady in the upper 50s throughout the period, with no frost or freeze expected.
No flood warnings are active yet, but additional alerts may be issued if rainfall rates increase or drainage becomes overwhelmed. Residents should stay weather-aware and plan for slower travel through Tuesday.
