Special Weather Statement
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.

* WHEN...Through Friday afternoon.
* IMPACTS...Excessive runoff may result in flooding of rivers,
creeks, streams, and other low-lying and flood-prone locations.
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...
- An atmospheric river will continue to impact the area through
much of the week and bring periods moderate to heavy rain to
the region. Sharp rises are occurring on area rivers,
especially those flowing off the Olympics and Cascades.
Urban and small stream flooding is possible for areas with
poor drainage.
Saturated soils will bring increased potential for landslides
and debris flows on burn scars.

Special Weather Statement
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.

Hydrologic Outlook
ESFSEW
Another storm system will impact western Washington tonight, with
additional rainfall between 2 to 2.75 inches. Snow levels this
evening will be between 6000-7000 feet and will decrease to
3800-4000 feet Friday morning. This combination of heavy rainfall
and high snow levels will lead already elevated rivers to rise,
potentially above flood stage. While the probability is low, the
Snoqualmie River has the greatest chance of minor flooding.
Please monitor the latest river forecasts from the National Weather
Service for additional information.
