Seattle, WA – Drivers across western Washington should brace for another wet stretch as heavy rain returns Tuesday night into Wednesday morning, October 1. Standing water, slick roads, and patchy fog could slow rush-hour traffic on I-5 and surrounding highways. Officials urge commuters to allow extra travel time and avoid speeding through water-covered lanes.
According to the National Weather Service, rainfall begins increasing late Tuesday, with the heaviest showers and a chance of thunderstorms arriving by Wednesday morning. Rain chances remain near 100 percent across King County, with localized totals topping a half inch in some areas. Winds from the south could gust up to 15 mph, adding to difficult driving conditions.
Seattle will see temperatures holding in the mid-60s during the day, dipping into the mid-50s by Wednesday night. The damp stretch is expected to continue into Thursday, with showers lingering through much of the week.
Travelers through downtown Seattle, SeaTac, and Bellevue should expect delays, especially during peak commuting hours. Low visibility from fog may also impact morning flights at Seattle-Tacoma International Airport. Residents are encouraged to check road conditions, keep headlights on, and secure outdoor items ahead of stronger gusts.
The wet pattern reinforces fall’s arrival across the region, with storm systems rolling in off the Pacific. While no major flooding is expected, forecasters warn that saturated soils could lead to minor drainage issues in urban areas.
Rain is expected to ease briefly Friday before another chance of showers returns for the weekend.
