Flood warning issued for Snoqualmie River, Tolt
February 21, 2012 · Updated 1:39 PM
The National Weather Service and Floodzilla are tracking weather and rain gages, and say the Snoqualmie River and the Tolt will bust their banks by tomorrow.
The NWS says strong west winds will raise snow levels and bring significant rain, as much as 6 inches, to the central Cascades. High water will come starting late Tuesday, cresting Wednesday, with widespread flooding from Fall City downstream through Carnation and Duvall. Much of the farmland and numerous roads will flood, the NWS predicts.
According to the Floodzilla website, which is operated by volunteers in Carnation, the Snoqualmie is expected to crest three feet above flood stage by 10 a.m. Wednesday at 34,000 cubic feet per second at Snoqualmie Falls. Downstream at Carnation, the river will crest nearly four feet above flood stage by 4 p.m.
This event should be similar to the Dec. 12, 2010 flood, which crested at about 33,000 cubic feet per second at the Falls.
The last major flood in the Valley, in January 2009, reached 60,000 cubic feet per second at the Falls.
