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
continue 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 3 to 6 inches of rain has been observed from
Friday night through Sunday afternoon and an additional 1 to
3 inches of rainfall is expected from Sunday night through
Monday night. Snow levels have risen 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.
