...RAIN AND SNOWMELT WILL CAUSE SIGNIFICANT RISES ON RIVERS AND
STREAMS THIS WEEKEND INTO EARLY NEXT WEEK...

Several weather systems will be moving through the Pacific
Northwest this weekend into early next week and will bring
periods of moderate to heavy rain. Highest rainfall amounts will
be over the Cascades with 2 to 4 inches likely. The central and
northeast Oregon mountains will receive 1 to 2 inches.

The combination of rain and snowmelt will increase flows on
rivers, creeks, and streams across the region with many reaching
bankfull by late in the weekend or early next week.

At this time, the following rivers are at the greatest risk of
reaching bankfull or flood stage early next week; the Grande Ronde,
John Day, Umatilla, Walla Walla, Imnaha.

Continue to monitor river forecasts for the latest details.
