Expires: Wed, 12/17 4:15pm Severity:  Moderate  Certainty: Observed

 
Details:
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 the rest of today. 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 ranfall acting as
a trigger.

Numerous landslides have already occurred in Whatcom, Skagit, King
Counties and others. 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.
