...HEAVY RAINFALL MONDAY THROUGH WEDNESDAY WILL LEAD TO AN INCREASED THREAT OF LANDSLIDES IN WESTERN WASHINGTON... Rainfall of 1 to 4 inches over the past several days has increased antecedent soil moisture to high levels across western Washington. Heavy rainfall of 2 to 6 inches across the lowlands and 4 to 10 inches over the Olympics and Cascades is expected Monday morning through late Wednesday. This amount of rain will put extra pressure on soil instability, leading to an increased threat of landslides and debris flows, especially from recent burned areas. 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.
