Flood Warning Continues, Risk of Landslides Increases

A Flood Warning continues for the Skokomish River while the risk of landslides increases.

The National Weather Service says a Flood Warning remains in effect of the Skokomish River as heavy rains will drive the Skokomish above the 16.5-foot flood stage again today (Mon. Dec. 21, 2020). The river should recede tonight and fall below flood stage late Tuesday. Minor flooding is forecast but moderate flooding is possible.

The river is expected to crest at 17.4 feet late this afternoon. At 17.5 feet, the Skokomish River will cause moderate flooding, with deep and quick flood waters inundating some residential areas, many roads, and much of the farm land in the Skokomish Valley. Inundated roads include the Skokomish Valley Road, Bourgault Road West, Purdy Cutoff Road, and Highway 106.

Also, elevated soil moisture across Western Washington will increase to near threshold as another round of moderate to heavy rain spreads across the region. Additional rainfall amounts of 1 to 2 inches in the lowlands and 2 to 3 inches in portions of the Olympics and Cascades can be expected through Monday night. This will put extra pressure on soil instability, leading to an increased threat of shallow landslides during this time period. The greatest threat area will generally be focused in the south Puget Sound Region, as well as the central and southern Cascades.
