ESFPQR
A series of systems will bring an extended period of wet weather
across northwest Oregon and southwest Washington through the
weekend. This will lead to rises on rivers and creeks, beginning
Wednesday evening, Dec 25th through at least Sunday, December 29th.
There is currently a 15-30% probability that rivers west of the
Cascades reach minor flood stage over the next ten days.
Heavy rainfall may also cause ponding of water or localized urban
flooding, especially in low lying areas or other areas with poor
drainage. This also increases the potential for landslides and
debris flows.
The exact track of these upcoming storms will influence rainfall
amounts, and thus the potential for flooding. Shifts in storm track
can change the current outlook, 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.

* WHEN...From 5 AM to 10 PM PST Monday.
* IMPACTS...Destructive waves may wash over beaches, jetties,
and other structures unexpectedly. People can be swept off
rocks and jetties and drown while observing high surf. Similar
wave conditions in the past have resulted in beach erosion and
damage to coastal properties and buildings. High water run-up
is expected on beaches and low- lying shoreline.
* ADDITIONAL DETAILS...There is a high threat for sneaker waves.
* WHAT...South winds 25 to 35 mph with gusts up to 55 mph expected.
* WHERE...This includes the Summer Lake area and the mountains
across Lake County and eastern Klamath County, and Modoc County.

limbs could be blown down and a few power outages may result.

the city of Ashland, Talent and Phoenix.

hazardous conditions along beaches and area shorelines. Waves
will inundate beaches and surge into normally dry areas.
Infrastructure damage and significant beach erosion can be
expected.

afternoon. Conditions are expected to slowly improve on
Tuesday, but another round of dangerous surf conditions can be
