...HEAVY RAINFALL THIS WEEK WILL LEAD TO AN INCREASED THREAT OF
LANDSLIDES IN WESTERN WASHINGTON...

Rainfall of up to 8 to 10 inches over the past several days has
increased antecedent soil moisture to high levels across western
Washington. Additional heavy rainfall of 1 to 4 inches across the
lowlands and 4 to 10 inches over the Olympics and Cascades is
expected through late Wednesday. Wet and unsettled conditions are
also favored to continue through the rest of the 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.

A mudslide was reported along I-90 Monday evening near North Bend,
causing highway closures and extensive delays. 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.
