...RIVERS RISING IN THE WASHINGTON CASCADES EARLY THIS WEEK...

Rains that brought rising river levels to the area, especially the
Washington Cascades over the weekend, will be compounded as another
round of heavier precipitation is fed by a strong atmospheric river
early This Week.

Currently a few locations on the Naches and Yakima Rivers are
forecast to reach action stage starting Tuesday and Wednesday (45 to
70 percent confidence) but the chances of reaching minor flood stage
are relatively low at this time (20 to 45 percent confidence).
