Significant rainfall over the past week has increased soil moisture to high levels across western Washington. Additional rainfall of 1 to 2 inches is expected through Friday. This amount of rain will continue to put extra pressure on soil instability, leading to an increased threat of landslides and debris flows, especially from recent burned areas, with this new rainfall acting as a trigger. Numerous landslides have already occurred in Whatcom, Skagit, King Counties and others. More landslides continue to be possible. Areas most susceptible to landslides debris flows under these conditions are steep coastal bluffs, other steep hillsides or road cuts, and recent burned areas. A diminishing threat of landslides and debris flows will continue for several days after the rain ends.
