King County closing Flood Warning Center, but will continue to monitor river levels


With rain diminishing and upper Snoqualmie River receding, the King County Flood Warning Center closed early Friday evening after an unusual May opening attributed to a combination of heavy rain and snowmelt from warm temperatures.


The King County Flood Warning Center closed at 5 p.m. on Friday, May 5, following an unusual spring opening in response to minor flooding on the Snoqualmie River.

The Flood Warning Center opened at 1:30 a.m. May 5, when the Snoqualmie River spilled its banks and caused minor flooding following several hours of heavy rainfall combined with snowmelt from warm temperatures.

Flood Warning Center employees will continue to monitor stream gages and weather reports. Real-time river level information is available online at
