The King County Flood Warning Center has issued a Phase 2 flood alert for the Tolt River, where minor flooding is now possible. The Flood Warning Center opened at 9:40 p.m. on Sunday, Feb. 14 as steady rain brought sharp rises to many King County river levels.
As of 11 p.m. Sunday, the Tolt River recorded a flow of 3,500 cubic feet per second (CFS), which is the threshold for a Phase 2 flood alert on that river. At these flows, only minor and isolated flooding could be expected along low-lying areas of the Tolt River east of Carnation.
Meanwhile, flows continue to climb on the Snoqualmie River, where the sum of the river’s three forks recorded a flow of 14,350 CFS at 11 p.m. Sunday, well beyond the Phase 2 flood alert threshold of 12,000 CFS. Despite these higher flows, only minor flooding is expected along low-lying areas of the Snoqualmie River, with the potential for water over a few roads.
Flood Warning Center employees will 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.
