Details:
Rainfall from the past week has increased soil moisture to high
levels across western Washington. Additional rainfall of of one to
three inches is expected with the system today into Wednesday
morning. 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. This rain event
could act as a trigger for new landslides.

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.
