...HEAVY RAINFALL THIS WEEK HAS LED 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. This significant 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 additional 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.

For more information about current conditions, visit
www.weather.gov/seattle, select Hydrology, and then scroll down
for the links to the landslide information pages.

427 AM PST Fri Dec 19 2025

...FLOOD WATCH REMAINS IN EFFECT THROUGH SATURDAY MORNING...

* WHAT...Flooding caused by excessive rainfall continues to be
  possible.

* WHERE...Portions of northwest and west central Washington,
  including the following counties, in northwest Washington, Grays
  Harbor. In west central Washington, King, Lewis, Pierce and
  Thurston.

* WHEN...Through Saturday morning.

* IMPACTS...Excessive runoff may result in flooding of rivers,
  creeks, streams, and other low-lying and flood-prone locations.
  Creeks and streams may rise out of their banks. Flooding may occur
  in poor drainage and urban areas. Storm drains and ditches may
  become clogged with debris. Area creeks and streams are running
  high and could flood with more heavy rain.

* ADDITIONAL DETAILS...
  - Rainfall from yesterday as well as expected showers today
    will allow for continued reactions and possible rises on area
    rivers. Additionally, those rivers that are seeing waters
    recede may see the rate at which these waters fall slow down.
    This will allow for potential flooding to continue into the
    weekend.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

You should monitor later forecasts and be alert for possible Flood
Warnings. Those living in areas prone to flooding should be prepared
to take action should flooding develop.
