afternoon at 415 PM PST.

* WHAT...Tidal overflow flooding expected.

* WHERE...Clatsop and Tillamook Coast, and South Washington

* WHEN...From 2 PM to 6 PM PST Monday.

* IMPACTS...Minor flooding, up to one foot above ground level,
during high tides is expected in the low lying areas near bays,
sloughs, and the lower reaches of the coastal rivers.

* ADDITIONAL DETAILS...Coastal flooding threat is due to a
combination of higher tides in addition to rivers running high
due to runoff from heavy precipitation on Monday. Total tides at
Toke Point, Tongue Point, and Garibaldi are forecast to be
around 9.5 feet. High river flows and runoff from heavy
precipitation will increase the flood potential in the tidally
influenced reaches and estuaries of coastal rivers.

A Coastal Flood Advisory means that tidal overflow flooding is
expected. Coastal residents in the warned area should be alert
for rising water, and take appropriate action to protect life and
property.

* WHAT...Southwest winds 15 to 25 mph with peak gusts up to 35 to 45
mph expected. Winds will be strongest west of the Willamette
Valley, along the Coast Range.

Coast Range Valleys and Mountains of Oregon, Willapa Hills and
Adjacent River Valleys of Pacific and Wahkiakum Counties, Lower
Columbia River and Cowlitz River Valleys, Central Willamette
Valley, Clackamas County Cascade Foothills, and South Washington
Cascade Foothills.

* WHEN...From 7 AM Monday to 4 AM PST Tuesday.

* IMPACTS...Gusty winds combined with very saturated soils will
increase the chances for downed trees and possible power outages.

* ADDITIONAL DETAILS...Winds are not expected to gust at peak
intensity for the entire duration of the advisory. Impacts are
more likely where the highest wind gusts occur. Confidence in the
extent and exact location of impacts is low but confidence in at
least isolated to scattered impacts is high.

Use extra caution when driving, especially if operating a high
profile vehicle. Secure outdoor objects such as garbage cans and
other objects that can easily blow around.

* WHAT...River and urban flooding caused by excessive rainfall is
possible. Landslides possible in areas of steep terrain, and
debris flows possible over recently burned areas.

* WHERE...Counties in Oregon: Benton, Clackamas, Clatsop, Columbia,
Hood River, Lane, Lincoln, Linn, Marion, Multnomah, Polk,
Tillamook, Washington, and Yamhill.

Counties in Washington: Clark, Cowlitz, Pacific, Skamania, and
Wahkiakum.


* WHEN...From late tonight through late Thursday night.

* IMPACTS...Excessive runoff may result in flooding of rivers,
creeks, streams, and other low-lying and flood-prone locations.
Landslides and debris flows are possible during this flood event.
People, structures, and roads located below steep slopes, in
canyons, and near the mouths of canyons may be at serious risk
from rapidly moving landslides.

* ADDITIONAL DETAILS...
- A prolonged atmospheric river is expected to bring periods of
heavy rain to northwest Oregon and southwest Washington
Monday through Wednesday, with periods of lighter rain
continuing Thursday into Friday. Rivers draining the coastal
mountains and several Willamette Tributaries have the highest
chance of flooding at 40 to 80%. Chances for flooding along
the Willamette mainstem remains low at less than 10%. Urban
flooding is possible and water on roadways will increase the
risk of hydroplaning. Landslides in areas of steep terrain
will be possible, as well as debris flows over recently
burned areas.
