June 10, 2022

Summary

The King County Flood Warning Center closed at 2 p.m. on Friday, June 10, as river levels receded from their peak flows following a strong late spring rainstorm that led to isolated minor flooding on the Snoqualmie River.

Story

The King County Flood Warning Center closed at 2 p.m. on Friday, June 10, after more than 12 hours of operation to monitor minor flooding from heavy rainfall. Flood Warning Center employees will monitor river conditions as another strong rainstorm could impact the region this weekend.

The Flood Warning Center opened at 12:45 a.m. on Friday, June 10, to monitor minor flooding along the Snoqualmie River, the result of a powerful late spring rainstorm that dropped more than 1 inch of rain across eastern King County.

While staying comfortably within the Phase 2 flood alert levels indicating minor flooding and few impacts to property or roads, the Snoqualmie River’s peak flow on Friday morning – approximately 14,920 cubic feet per second at about 2:15 a.m. – is the highest flow recorded on the Snoqualmie River in June since 1985.

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.
