Details:
Rainfall of 2 to 12 inches over the past several days has increased
soil moisture to very high levels across western Washington. 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.

Numerous landslides have already been reported in the western
Cascades in western Washington. More landslides are 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.
