Flood Warning Center opens as river levels rise

Persistent rainfall brings Snoqualmie River into Phase II flood alert level

As of 11:55 p.m. Sunday, the Snoqualmie River was flowing at 12,800 cubic feet per second (CFS), exceeding the Phase II flood alert threshold of 12,000 CFS for that river. Typically, only minor flooding in low-lying areas would be expected at this flow, with the potential for water over Neal Road and possibly a handful of other roads in the Snoqualmie Valley.

A Phase II flood alert level is the level of the County's four-phase warning system at which the Flood Warning Center activates to monitor conditions. The Flood Warning Center will remain open as long as flood conditions persist.

Flood Warning Center staff 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 http://www.kingcounty.gov/flood.

Updated information on flooding will also be posted on the King County website at www.kingcounty.gov, and via RPIN, the area's regional website at http://www.rpin.org. A recorded flood-information hotline is also updated each hour for citizens wanting information on flood conditions. The number is 206-296-8200 or 1-800-945-9263.

Citizens who need help interpreting flood information should call 206-296-4535 or 1-800-768-7932. Problems on County maintained roads can be reported by calling 206-296-8100 or 1-800-KC-ROADS.

An automated flood alert system is available and provides real-time warning of potential high water on more than a half-dozen rivers. King County residents and business owners can sign up to receive King County Flood Alerts by visiting www.kingcounty.gov/flood, or by calling 206-263-3400 during regular business hours to register by phone. Messages of potential high flows on any of King County’s major river systems can be sent by phone, text or email.
