Both the Snoqualmie and Tolt rivers reached minor flooding phases on Monday afternon after heavy rainfall pushed water levels higher.

The King County Flood Warning Center was activated on Feb. 22 to monitor potential flooding in low-lying areas. Minor flooding in low areas along both rivers could see minor flooding.

The Snoqualmie River had breached minor flooding stages at the sum of the three forks as of early Monday afternoon, according to Floodzilla. It was projected to crest at nearly 16,000 cubic feet per second on Monday afternoon. The flood stage is 12,000 cubic feet per second.

Levels near Carnation were expected to reach minor flood stages early Tuesday morning. The Tolt River was flowing at 4,230 cubic feet per second as of early Monday afternoon, with potential for minor levee seepage upstream of Carnation, a press release from King County states.
