ESFSEW An atmospheric river brought 3 to 5 inches of precipitation to the Olympic mountains Wednesday into Thursday morning with snow levels around 4000 feet. While precipitation will be much less with the systems beginning Friday the lack of much of a break will keep rivers over the Southwest Interior rising into the weekend. It is possible the lower reaches of the Chehalis could flood Saturday. The Skookumchuck near Bucoda, Newaukum near Chehalis and the Satsop near Satsop could reach action stage late Friday into Saturday. Please monitor the latest river forecasts from the National Weather Service for additional information.
