Hydrologic Outlook
ESFSEW
The bulk of the rainfall concentrated on areas south of the
Skokomish River basin so the chance of the river cresting much
higher than forecast is very low. Another batch of rain overnight
will result in cresting higher than it is, but it is not expected to
exceed flood stage.
Please monitor the latest river forecasts from the National Weather
Service for additional information.

Hydrologic Outlook
ESFSEW
A series of progressive systems will bring rain to western
Washington through the weekend. The heaviest rainfall is expected
through Saturday, with rainfall amounts over the Olympic Peninsula
ranging between 2-3 inches. This will lead to rises on the Skokomish
River in Mason County. With the Skokomish River running high and
with snow levels expected to be between 5500-7500 feet, expect
sharper rises on the river late Friday into Saturday. Flooding will
be possible into the weekend.
Please monitor the latest river forecasts from the National Weather

Flood Watch
* WHAT...Flooding caused by excessive rainfall is possible.
* WHERE...Portions of northwest and west central Washington,
including the following counties, in northwest Washington, Mason,
Skagit and Whatcom. In west central Washington, King and Snohomish.
* WHEN...From late tonight through late Saturday night.
* IMPACTS...Excessive runoff may result in flooding of rivers,
creeks, streams, and other low-lying and flood-prone locations.
Where heavy rain occurs, the relatively high rain rates could
produce flash flooding/debris flows on the more sensitive burn
scars. It could also cause ponding or nuisance flooding in urban
areas and small streams where drainage is poor or drains are
clogged by leaves.
* ADDITIONAL DETAILS...
- Rainfall forecasts between 3 to 5 inches with locally higher
amounts possible through Saturday night. Snow levels will
range from 8000 to 9000 feet. This amount of rainfall will
drive some of the rivers in the watch area to near flood
stage. The most likely rivers to reach flood stage is the
Skokomish, Snohomish, Skykomish, and Snoqualmie, and to a
lesser extent, the Skagit, Stillaguamish, and Nooksack
rivers.

Hydrologic Outlook
ESFSEW
A moderately strong atmospheric river will impact western Washington
Friday through Saturday night, bringing moderate to heavy rainfall
to the region. Mean rainfall forecast remains between 2 to 4 inches
with locally 5+ inches, with the heaviest rain on track to fall over
the Olympic Peninsula and over the northern and central Washington
Cascades. While the Skokomish River is the only river currently
forecast to enter minor flood stage on Saturday, many other rivers
are forecast to reach action stage on Saturday, including the
Bogachiel River on the Olympic Peninsula and the Skagit, Snohomish,
Skykomish, and Snoqualmie Rivers in the Cascades. Some uncertainty
remains over rainfall amounts over the mountains, and river
conditions will continue to be closely monitored.
Where heavy rain occurs, the relatively high rain rates could
produce flash flooding/debris flows on the more sensitive burn
scars. It could also cause ponding or nuisance flooding in urban
areas and small streams where drainage is poor or drains are clogged
by leaves.
Please monitor the latest river forecasts from the National Weather
Service for additional information.
