Synopsis: An atmospheric river will bring abundant moisture to the
region with an incoming system Sunday through Monday. Rainfall
amounts of 1 to 2 inches are expected along the Oregon and
Washington Cascade crest and in the higher mountains of northeast
Oregon and southeast Washington. These amounts may be increased
locally by 1 to 2 inches of snow melt from what remains of the high
mountain snowpack.
Where: The East Slopes of the Washington and Oregon Cascades, The
Northern and Southern Blue Mountains, The Blue Mountain Foothills of
Washington and Oregon, Wallowa County and the Grande Ronde Valley.
When: Rain will arrive along the Cascades early Sunday morning and
in the eastern mountains late Sunday morning and afternoon. Rain
will taper off Monday afternoon and evening.
What: The precipitation and possible snow melt will lead to rises on
area creeks, streams and rivers. Rivers are low enough that only the
Naches River at Cliffdell and the Naches River at Naches are
expected to reach bankfull Monday and only by a few inches at those
locations. However, with the heavier periods of rain rapid rises
will be possible on smaller streams and creeks, especially in
Wallowa County and this is the main concern for the next couple of
days.
An update will be provided Sunday morning.
Two atmospheric rivers are expected to arrive Sunday through
Tuesday. Heavy rain is expected Sunday morning into Monday with
additional rainfall through Tuesday. Snow levels will be high. This
combination could push rivers in the watch area close to flood stage
beginning on Monday. Heavy rain may also lead to flooding in urban
areas.
* WHAT...Flooding caused by excessive rainfall continues to be
possible.
* WHERE...A portion of west central Washington, including the
following county, Lewis.
* WHEN...From late tonight through Wednesday 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.

Where: Chelan and Pend Oreille counties in Washington. Boundary,
Bonner, Kootenai, Shoshone, Benewah, Latah, Lewis and Nez Perce
counties in Idaho.
What: Moderate to heavy rainfall will lead to rises on area creeks,
streams, rivers, and lakes. Rainfall totals of 1 to 2 inches at the
crest of the Cascades and mountains of northeast Washington and the
Idaho Panhandle is currently forecast.
An Areal Flood Watch has been issued for Lewis and Shoshone Counties
in Idaho. Moderate to heavy rainfall combined with rapid snowmelt
over the Clearwater Mountains may cause creeks and streams in
eastern Lewis County and southern Shoshone County to rise out of
their banks.
When: Beginning late Sunday morning along the crest of the Cascades
and moving into eastern Washington and the Idaho Panhandle Sunday
afternoon. Heaviest rainfall will occur between Sunday evening and
Monday morning.
This will be the last Hydrologic Outlook update.

What: Moderate rainfall leading to rises on area creeks, streams,
rivers and lakes. Monday morning rainfall could be locally heavy,
especially across Idaho. There is low confidence of the potential
for isolated rock or mud slides. The rain will largely be beneficial

A late season atmospheric river will bring moderate to heavy
precipitation from Sunday afternoon through Tuesday across all of
western Washington. Heavy rainfall rates are possible over the
southwest Olympics, and the Cascades. Total rainfall amounts will
range from 1 to 2 inches in the lowlands, and 2 to 4 inches in the
mountains. Snow levels above 5000 feet will result in most
precipitation falling as rain. This will result in rivers running
unusually high, with the Skagit, Snohomish, Skykomish, White, and
Skokomish Rivers potentially over action stage. The Snoqualmie River
potentially will reach minor flood stage. This may impact any use of
the river flood planes that are normally dry this time of year.
Rivers will crest sometime between Sunday and Tuesday.
The next update will be provided Friday afternoon.
Please monitor the latest river forecasts from the National Weather
Service for additional information.
