Special Weather Statement

Special Weather Statement issued December 14 at 10:38AM PST by NWS Seattle WA

Rainfall from the past week has increased soil moisture to high
levels across western Washington. Additional rainfall of around 2-6
inches is expected early this week. 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.
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.
