UPDATE: As of 9 a.m. on Friday, Nov. 13, the sum of the Snoqualmie River’s three forks recorded a flow of 20,610 cubic feet per second (CFS), just past the 20,000 CFS threshold for a Phase III flood alert. At these flood levels, low-lying areas of the Snoqualmie Valley could be inundated with floodwaters of various depths, and road closures are possible.
The King County Flood Warning Center opened at 6 a.m. Friday to monitor flood conditions. Flood patrol crews are in the field this morning to get a firsthand look at flood conditions, and Flood Warning Center employees 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.
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. Reach the Flood Warning Center at 206-296-8200 or 1-800-945-9263. Interpreter assistance in multiple languages is available.
King County offers everyone 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.
