StoryThe King County Flood Warning Center is closing at 10 p.m. on Tuesday, Oct. 22, as flows continue to recede along the Snoqualmie and Tolt rivers, where flooding occurred from heavy rainfall on Oct. 21.
The Flood Warning Center opened at 6:15 p.m. on Monday, Oct. 21 after an intense fall storm dumped several inches of rain across the central Cascade Mountains. Rainfall swiftly brought the Snoqualmie River to a Phase 4 flood alert level, with significant flooding across much of the Snoqualmie Valley.
The Tolt River, also driven by heavy rainfall, reached a Phase 3 flood alert level that included moderate widespread flooding in low-lying areas along the river upstream of Carnation.
King County employees will continue to monitor stream gauges and weather reports, and they will provide updated information on river conditions as necessary. Real-time river level information is available online at kingcounty.gov/flood.
