King County closes Flood Warning Center as rivers begin to recede

The King County Flood Warning Center closed at 8 a.m. this morning after more than two days of around-the-clock operation to monitor flood flows on several rivers.

The Flood Warning Center opened at 12:30 a.m. on Sunday, March 9, in response to minor flooding on the Snoqualmie and Tolt rivers.

Fueled by a powerful late-winter storm, the Snoqualmie, Tolt and Green rivers all reached Phase III flood alert levels, with moderate flooding along some stretches. Meanwhile the Cedar River reached a Phase II flood alert level, with minor flooding.

According to the National Weather Service, the Cedar River reached a high point of 12.55 feet. For the Cedar, 13 feet is considered minor flooding.

Flood Warning Center staff will continue to 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.

King County offers free access to KC Flood Alerts, an automated system that allows subscribers to receive customized alerts of potential flooding for any or all of King County’s six major river systems.

Immediate notifications about pending high water are sent to email, smart phone text or voicemail, providing subscribers with the maximum amount of warning about potential high water.

Find the KC Flood Alerts link 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.

Updated information on flooding will also be posted on the King County website at kingcounty.gov.

During river flooding events, King County serves as a clearinghouse for information on flood conditions, operating a recorded message center with continuous updates of river gage readings and flood phases and other related information.
