King County Flood Warning Center opens to monitor rising Snoqualmie River flows

The King County Flood Warning Center opened Monday evening, Nov. 1 at 8:10 p.m. to monitor rising flows on the Snoqualmie River due to persistent rainfall in the area.

As of 9:30 p.m. Monday, the sum of the Snoqualmie River's three forks totaled 12,260 cubic feet per second (cfs) - just above the 12,000 cfs threshold for a Phase II flood alert level on that river. Despite the high flows, only minor lowland flooding is expected.

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.

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, or 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 in flood areas. 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 now 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 e-mail.
