NoticeSpecial Weather Statement from NWS Seattle WA
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.
