Record Rainfall Brings Flooding, Mudslides To Western Washington
Friday firmly landed as one of the wettest days ever recorded in the Seattle area. The rain continues Saturday.

SEATTLE, WA — An unrelenting downpour brought flooding to rivers, streets and urban areas Friday, as Puget Sound shattered some all-time precipitation records. According to the National Weather Service, storm totals in Snohomish County and points south were expected to hit between 5 and 10 inches of rain by the time the weather begins to taper off Saturday night. In Seattle, Friday landed among the top five wettest days ever documented, since records began in 1945.
