March 8, 2026 – 7 p.m.
UPDATE: Rainfall has eased across much of eastern King County, and river levels are dropping throughout the foothills, and the King County Flood Warning Center closed at 6:30 p.m., after slightly less than five hours of monitoring flooding along the Snoqualmie River Sunday afternoon.
While drier weather across the region is giving rivers the opportunity to return to normal flows, we’ll continue to monitor weather data in case these improving conditions change unexpectedly.
King County’s Flood Warning Center is staffed 24/7 during flood events, serving as an information clearinghouse for the public and other agencies responsible for ensuring public safety.

King County Flood Warning Center opens to monitor minor flooding along Snoqualmie River
Sunday, March 8 – 3:30 p.m.
Heavy rainfall across the Cascade foothills on Sunday, March 8 brought the Snoqualmie River up to minor flood levels, and the King County Flood Warning Center opened to monitor impacts to roads in low-lying areas.
As of 3:30 p.m. on March 8, the sum of the Snoqualmie River’s three forks was recorded at 13,300 cubic feet per second, surpassing the Phase 2 flood alert threshold of 12,000 CFS. At these flows, some minor flooding could occur – with potential floodwaters along Southeast Reinig Road, Meadowbrook Road, Mill Pond Road, Neal Road Southeast, and a handful of other roads.
Widespread flooding is not expected from this current storm, and forecasts point to a return to lower river levels once the rainfall eases.
