The National Weather Service in Seattle has issued a Flood Watch, in effect from late this morning through late Tuesday night, due to an incoming atmospheric river forecasted to bring periods of heavy rain across the region. The watch covers parts of Grays Harbor, King, Lewis, Pierce, Skagit, Snohomish, and Thurston counties, as reported by the National Weather Service.
"Precipitation is expected at times through Monday night, allowing for additional rises on area rivers," according to the National Weather Service. The rainfall, driven by an atmospheric river, may lead to flooding in urban areas and regions with poor drainage. Homeowners and residents in affected areas are advised to stay alert and prepared for possible flood warnings. The forecast predicts cloudy skies throughout the week, with temperatures in the low to mid-50s during the day and slightly cooler overnight, creating conditions for continued soil moisture saturation.
The National Weather Service warns of potential flooding and landslides due to intense and sustained rainfall, with rain totals in the Olympics and Cascades expected to reach 3 to 5 inches, and possibly more in localized areas. Snow levels are expected to rise above 7,000 feet Sunday, further straining the saturated ground. "Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations." Residents in affected areas should monitor weather updates, follow local authority guidance, and prepare for possible emergency conditions, as both rising waters and unstable land pose significant threats.
