The King County Flood Warning Center opened early today (Monday, Dec. 18), to monitor minor flooding along the Snoqualmie River and closed around 4:30 p.m.

As of 8:30 a.m. Monday, the sum of the Snoqualmie River’s three forks was flowing at 13,730 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 is 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.

This website is a valuable preparedness resource, with all of the latest information about river levels and road conditions, plus weather reports and other critical links. It also provides a KC Flood Alerts app, providing automated alerts on potential flooding for subscribers.

Reach the Flood Warning Center at 206-296-8200 or 1-800-945-9263. Interpreter assistance in multiple languages is available.

Questions or assistance with flooding on smaller streams or urban drainage problems can be called in to 206-477-4811 during business hours, or 206-477-8100 after hours or on weekends.

Problems on County maintained roads can be reported by calling 206-477-8100 or 1-800-KC-ROADS.
