ESFPQR
A series of storm systems will continue to bring a wet weather
pattern across northwest Oregon through the weekend. This will lead
to rises on rivers and creeks through at least December 30th. As of
2 AM PST December 28th, the Luckiamute River remained just above
minor flood stage and is forecast to remain right at or just above
minor flood stage through Saturday afternoon before falling below
flood stage Saturday evening, Dec. 28th. Other rivers across
northwest Oregon remained below minor flood stage, however river
levels will continue to rise. With the rising river levels, there is
a 40% chance that the Pudding River at Aurora will also reach minor
flood stage sometime on December 30th. In addition, there is a
15-25% chance that the Wilson River, Marys River, Mohawk River and
Siletz River will reach minor flood stage. The Siuslaw River has a
35% chance of reaching minor flood stage.
Heavy rainfall may also lead to ponding of water, general lowland
flooding and localized urban flooding, especially in low lying areas
or other areas with poor drainage. Heavy rainfall will also increase
the potential for landslides in areas of steep terrain and debris
flows over areas that have been burned by wildfires over the past
few years.
There is still some uncertainty regarding the exact track of the
Saturday night/Sunday system and associated rain amounts. There is
currently a 10% chance the southern Willamette Valley will receive
2-2.5" of rain and the adjacent higher terrain of the Coast Range
and Cascades will receive 3-4" of rain Saturday evening through
Sunday morning. This represents the worst case scenario, which would
result in more widespread flooding issues. That said, the most
likely scenario is 1-1.5" of rain in the southern Willamette Valley
and 2-3" in the adjacent higher terrain of the Coast Range and
Cascades. This would result in minor and less widespread flooding.
Shifts in the forecast storm track can change the current outlook
and probabilities for river flooding, so be sure to monitor
weather.gov/portland for the latest weather updates, as well as any
watches, warnings, or advisories that may be issued. To view the
latest river forecasts, visit water.noaa.gov/wfo/pqr.
