Seattle, WA – Rain returns in force to western Washington early this week, raising concerns for commuters and travelers. By Tuesday night, a 100% chance of rain and patchy fog could reduce visibility and create slick road conditions along I-5 and surrounding highways.
According to the National Weather Service, steady rain begins Monday afternoon with widespread showers strengthening through Tuesday. South winds at 6 to 10 mph may push rainfall across King, Snohomish, and Pierce counties, with totals between a quarter and half an inch. Drivers should plan extra travel time and avoid distractions, especially during the Tuesday evening rush when fog and heavy rain overlap.
Seattle residents can expect rain every day through Thursday, with a thunderstorm risk emerging late Tuesday into Wednesday. Wednesday night may see another round of heavier showers before conditions ease slightly into Thursday. Daytime highs remain in the upper 60s, but the first days of October will feel cooler and unsettled.
Power outages remain possible as wet conditions and wind combine. Residents should charge devices, secure outdoor items, and prepare for delays on ferries and mountain passes. Road crews warn that ponding on low-lying stretches of I-5 and I-90 could cause hydroplaning during peak rainfall.
The storm pattern continues through the week, marking a sharp seasonal shift as October begins Wednesday. More advisories are possible as the fall weather system lingers.
