The King County Flood Warning Center has issued a Phase 2 flood alert for the Green River, where minor flooding could possibly occur in low-lying areas of the Green River Valley upstream of Auburn.
The Flood Warning Center opened at 12:30 a.m. on Sunday to closely monitor river flooding from heavy and persistent rainfall.
As of 5:30 p.m., the Green River at Auburn slightly exceeded the Phase 2 flood alert threshold of 7,000 cubic feet per second (CFS). At these flows, floodwaters could come in to low-lying areas of the largely agricultural and rural areas along the river upstream of Auburn. No flood impacts would be expected in Auburn and areas downstream of Auburn at the current river flows.
River levels remain high on rivers across King County as a result of the heavy rainfall that swept across the region Feb. 3-4, including on the Tolt and Snoqualmie rivers, which both remain at Phase 2 flood alert levels.
Flood Warning Center employees will continue to monitor stream gauges 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 gauge 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.
