...FLOOD WATCH REMAINS IN EFFECT FROM LATE TONIGHT THROUGH LATE
THURSDAY NIGHT...
* 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.

to the area, especially the Washington Cascades, through this
weekend. Another system fed by a strong atmospheric river early next
week will bring heavier rain amounts. Currently a few locations on
the Naches and Yakima Rivers are forecast to reach action stage

...Flood Potential Outlook for quick rises on rivers, creeks and
streams in portions of Coos and Douglas counties in Oregon...
A persistent storm track into the Pacific Northwest will bring
periods of rain, some heavy, to Coos and Douglas counties Sunday
through Wednesday. The time frame for heaviest rainfall appears to
be Monday night to Wednesday. Right now, rain amounts of 2 to 4
inches are most likely with the heaviest amounts across northern
Coos County and northern Douglas County along the Lane County
border. Lesser amounts are expected in the Umpqua Basin south of
Roseburg. Heavier rain amounts and flood impacts are more likely
farther north.
Main stem rivers in our area are currently running very low for this
time of year and we are not expecting river flooding. In fact, none
of the local river gauges are currently forecast to even get close
to flood stage. However, water levels could rise quickly, especially
around mid week and around some of the flashier creeks. This could
be dangerous for anyone near the water. Local ponding of water on
roadways could also be a hazard.
Please be aware that forecasts could change. While we are not
anticipating any watches or warnings at this time, watches and
warnings may be issued by the National Weather Service if the
situation worsens. This product will be updated or be allowed to
expire as new information becomes available.
