King County Flood Warning Center issues Phase 2 flood alert for Tolt River


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 perFlood Control Zone District Logo 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
