Seattle, WA – Washington drivers along I-90 should prepare for heavy rain on Friday, with the National Weather Service predicting a 100% chance of precipitation. Starting Friday morning, rain will blanket the region, making for hazardous road conditions. Gusts of up to 21 mph are expected, which could reduce visibility and create slick surfaces on highways, including I-90. Rainfall totals could reach up to half an inch, increasing the risk of hydroplaning and flooding in low-lying areas.
According to the National Weather Service, the rain will likely persist throughout the day, with the heaviest downpours occurring during morning and evening commutes. Drivers are urged to slow down, maintain safe distances, and monitor traffic reports for updates on possible delays or accidents. Flash flooding could affect portions of I-90 and surrounding roadways, making alternative routes advisable for those commuting long distances.
The rain will continue into Friday night, with a 50% chance of lingering showers before clearing up Saturday morning. With partly sunny skies forecast for the weekend, the worst of the storm will pass, but caution is still advised for any residual road slickness or debris on major highways.
