* WHAT...South winds 25 to 35 mph with gusts between 40 and 50 mph
expected.
* WHERE...Grande Ronde Valley.
* WHEN...Until 10 PM PST this evening.
* IMPACTS...Gusty winds will blow around unsecured objects. Tree
limbs could be blown down and a few power outages may result.
* WHAT...Flooding caused by excessive rainfall remains possible.
* WHERE...Portions of northwest Oregon and southwest Washington,
including the following counties: in Oregon, Benton, Clackamas,
Clatsop, Columbia, Hood River, Lane, Lincoln, Linn, Marion,
Multnomah, Polk, Tillamook, Washington, and Yamhill. In
Washington, Clark, Cowlitz, Pacific, Skamania, and Wahkiakum.
* WHEN...Through late Tuesday night.
* IMPACTS...Excessive runoff may result in flooding of rivers,
creeks, streams, and other low-lying and flood-prone locations,
especially for rivers draining the Willapa Hills and Oregon Coast
Range. Flooding may occur in poor drainage and urban areas.
Landslides are possible through this period, especially over the
Cascades due to heavy rainfall above 7,000 feet combined with
snowmelt. There is low probability for debris flows as rainfall
rates are not expected to meet thresholds over recently burned
areas.
* ADDITIONAL DETAILS...
- An atmospheric river and series of frontal systems will
produce periods of heavy rainfall over northwest Oregon and
Southwest Washington through Monday. The heaviest rain will
be over the coast, Coast Range, Willapa Hills, and Cascades
where rain totals through Monday night will range from 4 to 6
inches, with locally higher amounts possible. Snow levels
will rise to above 7,000 feet on Sunday, and snow melt due to
rain falling on the Cascade snow pack could cause additional
flooding concerns for drainages from the Cascades along with
enhanced risk of landslides.

ESFBOI
Moderate to heavy rain and low elevation snowmelt today and
Monday will lead to rises on rivers, creeks, and streams across
portions of southeast Oregon and southwest Idaho (particularly the
Weiser River Basin). Saturated or frozen soils in some areas will
increase runoff. Snow and ice may clog culverts, storm drains, and
side ditches causing water to back-up and pond in low lying and
poor drainage areas. Additionally, ice jams could develop on any
waterways with existing ice cover and cause localized flooding.
Rivers in these areas will continue to run high through the week
with some rivers potentially reaching bankfull or minor flood
stage.
Those with interests along rivers, creeks and streams should
continue to monitor the forecast as there is uncertainty in how
much response the lower elevation rivers, creeks and streams will
see. Stay tuned to the forecast for the latest temperature and
precipitation trends, along with any warnings or advisories that
may be issued.
