King County Flood Warning Center opens to monitor flooding on Snoqualmie River
SEATTLE — The King County Flood Warning Center opened at 10:30 a.m. on Thursday, Oct. 20, after several hours of heavy rain brought minor flooding to the Snoqualmie River.
As of 10:30 a.m., the sum of the Snoqualmie River’s three forks was flowing at 15,000 cubic feet per second (CFS), well above the Phase 2 flood alert threshold of 12,000 CFS.
At these flows, only minor flooding in low-lying areas of the Snoqualmie Valley could be expected.
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.
King County offers everyone free access to KC Flood Alerts, an automated system that allows subscribers to receive customized alerts of potential flooding for any or all of King County’s seven major river systems.
