Special Weather Statement
Issued: 11:33 PM Dec. 17, 2025 – National Weather Service
...HEAVY RAINFALL ON WILL LEAD TO AN INCREASED THREAT OF
LANDSLIDES IN WESTERN WASHINGTON...

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 Friday. 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 rainfall acting as a trigger.

Numerous landslides have already occurred in Whatcom, Skagit, King
Counties and others. More landslides continue to be 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.
