The King County Flood Warning Center opened at 6:30 a.m. on Friday, Nov. 13 after several hours of heavy rain brought minor flooding to the Snoqualmie River.

As of 7:30 a.m., the sum of the Snoqualmie River’s three forks was flowing at 19,340  cubic feet per second (CFS), well above the Phase II flood alert threshold of 12,000 CFS, and just short of the Phase III flood alert threshold of 20,000 CFS.

At these flows, minor flooding is expected in low-lying areas of the Snoqualmie Valley.

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, or at 206-296-8200 or 1-800-945-9263.
