The King County Flood Warning Center closed atrsz_kcfcd_21 2:15 p.m. on Friday, Oct. 29, after opening at midday on Thursday, Oct. 28, to monitor moderate flooding on the Snoqualmie and Tolt rivers.

The Flood Warning Center opened at 1:30 p.m. as an intense rainstorm swept into the region, resulting in rapidly rising river levels across the region. The Snoqualmie and Tolt rivers each reached a Phase 3 flood level, with numerous roads closed by floodwaters. 

Flood patrols dispatched by the Flood Warning Center were in the field during the storm to closely assess conditions and to note any impacts the storm might have had on flood risk reduction infrastructure, such as levees.

Flood Warning Center employees answered questions from the public and other agencies, maintained contact with flood response workers, and kept abreast of the latest weather forecast information and dam operations.

County employees will continue to monitor stream conditions and weather forecasts to ensure public safety, and real-time river level information is available online at
