The King County Flood Warning Center closed at 9:30 p.m. on Monday, Nov. 15 as rivers that had been brought to minor and moderate flood levels for several days due to heavy rainfall slowly receded.
StoryThe King County Flood Warning Center closed at 9:30 p.m. on Monday, Nov. 15, following more than a day and a half of round-the-clock operation to monitor rising river levels after a strong rainstorm swept across the region and sent river flows higher for several days.
The Flood Warning Center opened at 2:30 a.m. on Sunday, Nov. 14 to monitor minor flooding on the Snoqualmie River, which eventually rose to a Phase 3 flood alert level with moderate flooding across the lower Snoqualmie Valley. The Tolt River also reached a Phase 2 flood alert level, with minor flooding along the river upstream of Carnation.
Flood patrols dispatched by the Flood Warning Center were in the field during the storm to closely assess conditions and to note any impacts the storm might have had on flood risk reduction infrastructure, such as levees.
Flood Warning Center employees answered questions from the public and other agencies, maintained contact with flood response workers, and continuously updated information on weather forecasts and dam operations.
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 gauge 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.
