The King County Flood Warning Center has issued a Phase II flood alert for the Cedar River, whereFlood Control Zone District Logo minor flooding could be expected, while moderate flooding could occur upstream of Auburn along the Green River, which has just reached Phase III flood alert level.

As of 8:30 a.m. Monday, March 10, the Cedar River at Landsburg recorded a flow of 2,960 cubic feet per second (CFS), slightly higher than the 2,800 CFS threshold for a Phase II flood alert. At these flows, minor flooding could be expected in low-lying areas along the Cedar River, including possible water over Jones Road near 156th Place Southeast.

The Flood Warning Center, which has been open since 12:30 a.m. on March 9, continues to monitor additional minor flooding on other river systems, including the Green River, which exceeded the Phase III flood alert threshold of 9,000 CFS at the Auburn gage at 7 a.m. Monday. At these flows, rural areas along the Green River upstream of Auburn could expect to see minor to moderate flooding.

The Snoqualmie and Tolt rivers have both receded after a weekend of minor to moderate flooding.

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 kingcounty.gov/flood.
