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, December 25th through at least Sunday, December 29th. There is currently a 15-30% probability that rivers west of the Cascades will reach minor flood stage over the next ten days, except for rivers in southwest Washington which have less than a 5% chance. Heavy rainfall may also lead to ponding of water and localized urban flooding, especially in low lying areas or other areas with poor drainage. Heavy rainfall will also increase the potential for landslides and debris flows in areas of steep terrain. 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.
