The King County Flood Warning Center issued a Phase 3 flood alert for the Snoqualmie River on Monday, Feb. 15, with the potential for widespread, moderate flooding.
As of 8:30 a.m. Monday, the sum of the Snoqualmie River's three forks recorded a flow of 20,060 cubic feet per second (CFS), just above the Phase 3 flood alert level threshold. At these flows, several roads could overtop with floodwaters and close, including Fall City-Carnation Road, Tolt Hill Road Northeast and Northeast 124th Street.
Flows on many King County rivers experienced sharp rises Feb. 14 as a result of heaving rainfall, including the Tolt Rivers, which each reached Phase 2 flood alert levels and saw minor flooding.
Flood Warning Center employees will continue to monitor stream gages and weather reports, and will provide updated information on river conditions as necessary. Real-time river level information is available online at kingcounty.gov/flood.
During river flooding events, King County serves as a clearinghouse for information on flood conditions, operating a recorded message center with continuous updates of river gage readings and flood phases and other related information. Reach the Flood Warning Center at 206-296-8200 or 1-800-945-9263. Interpreter assistance in multiple languages is available.
