...SNOW MELT AND RAIN WILL LEAD TO AN INCREASED THREAT OF
LANDSLIDES IN WESTERN WASHINGTON...

There is a continued threat of landslides for the lowlands of
western Washington for areas where there is melting snow and any
rainfall saturating the soil. The landslide threat will continue
through Saturday for elevations below about 1500 feet.

Melting snow is very efficient at increasing soil moisture and is
not well represented in the landslide indices. As such, the threat
is higher than the indices suggest. Additional shower activity
through Saturday will put extra pressure on soil instability,
leading to further increased threat of landslides.

Areas above around 1500 feet in elevation will see mostly snow
and freezing temperatures and will not be affected.

www.weather.gov/seattle, select Hydrology, and then scroll down
