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. This weather system will
result in an increased risk for flooding. Forecast rain
amounts from 4 AM Monday through 4 AM Thursday range from 4
to 6 inches in the Cowlitz Valley, lower Columbia,
Portland/Vancouver metro and northern Willamette Valley, 2 to
4 inches in the central Willamette Valley, and 1.5-2.5 inches
in the southern Willamette Valley. Forecast rain amounts
reach 6 to 12 inches in the Cascades, Cascade foothills,
Coast Range and the coast, except 2-4 inches from Florence to
Newport and in areas of higher terrain in Lane County. Rivers
draining the coastal mountains and several Willamette
Tributaries have a 30 to 60% chance of reaching minor flood
stage or higher. The Pudding River at Aurora and Johnson
Creek at Sycamore have an 80% chance of reaching minor flood
stage or higher. Chances for flooding along the Willamette
mainstem remains low at 5-15%. Urban flooding is possible and
water on roadways will increase the risk of hydroplaning and
car accidents. Landslides in areas of steep terrain will be
possible, as well as debris flows over recently burned areas.
