Flooding and Landslides

Another round of strong southwesterly winds is expected Wednesday afternoon through Thursday morning. Sustained speeds of 20 to 35 mph and gusts up to 55 mph are anticipated for the Columbia Basin, Palouse, Spokane/CdA area, and Blue Mountains.

A handful of Flood Warnings, River Flood Warnings, and Flood Advisories have been issued across Washington and Idaho due to a prolonged period of rain and snowmelt causing rapid rises on rivers, streams, and creeks, resulting in flooding of low-lying areas. In addition, soils are extremely saturated, increasing risk for landslides in areas of steep terrain and near recent burn scars.
