UPDATE: Flood Warning Center closes as minor flood threat eases along Snoqualmie River
UPDATE: King County closes Flood Warning Center but will continue monitoring rainfall
UPDATE – 2:15 p.m., Jan. 28, 2024 – With rainfall easing and little precipitation in the immediate forecast, we closed our Flood Warning Center at 1:45 p.m. on Sunday, Dec. 10, after just a few hours of operation monitoring minor flood conditions along the Snoqualmie River.
The Flood Warning Center opened at 10 a.m. Sunday when the Snoqualmie River reached a minor flood phase, with the potential for floodwaters to overtop roads and inundate property in low-lying areas along the river.
A midday break in the rainfall across portions of eastern King County has led to slowly receding river levels in the upper Snoqualmie watershed. Flood Warning Center staff will continue to monitor river levels and weather forecasts.

King County opens Flood Warning Center to monitor minor flooding potential along Snoqualmie River
Jan. 28, 2024 – 10:30 a.m.
It’s been a soggy couple of days across the region, and all that rainfall has led to possible minor flooding along the Snoqualmie River. The King County Flood Warning Center opened at 10 a.m. on Sunday, Jan. 28, to monitor minor flooding along the Snoqualmie River.
As of 10 a.m. Sunday, the sum of the Snoqualmie River’s three forks was recorded at 12,100 cubic feet per second (CFS) – just slightly higher than the Phase 2 flood alert threshold of 12,000 CFS. At these flows, minor flooding could occur in low-lying areas along the Snoqualmie River. Significant flood impacts to roadways and other public infrastructure are not expected as a result of this minor flood event.
King County Flood Warning Center employees are monitoring stream gauges and weather reports to provide updated information on river conditions as necessary. Find real-time river level information is available online at kingcounty.gov/flood.
Rainfall has led to rising flows on rivers and streams across King County, but no other rivers are expected to flood as a result of this storm.
