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.
