Description:
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.
