* WHEN...From late Wednesday night through late Friday night.

* IMPACTS...Excessive runoff may result in flooding of rivers,
creeks, streams, and other low-lying and flood-prone locations.
Flooding may occur in poor drainage and urban areas. Storm drains
and ditches may become clogged with debris. Area creeks and
streams are running high and could flood with more heavy rain.
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...
- An atmospheric river is forecast to bring periods of heavy
rain to northwestern Oregon and southwestern Washington at a
time when area rivers continue to run high and soils remain
saturated following heavy rain earlier in the month. During
initial heavy rainfall on Thursday, the urban and small
stream flooding threat will be most urgent, although the
details of precise timing and location of the highest risk
remains uncertain at this time. As runoff works its way
downstream, the river flooding threat will increase Thursday
night into Friday, with numerous area rivers now forecast to
reach at least Minor flood stage.
