Hydrologic Outlook issued March 12 at 2:09PM PDT by NWS Pendleton OR

Summary: ESFPDT Heavy rain and mountain snow through Friday evening followed by unusually warm temperatures this weekend will lead to high water levels on many mountain streams and rivers. Currently the Grande Ronde River at Troy, the Umatilla River at Gibbon, the Walla Walla River at Touchet, The Klickitat River near Pitt and the Naches River at Naches are all forecast to reach Action Stage by Friday evening and continue into the weekend before receding in the late weekend or early next week. At this time, these locations are not expected to reach minor flood stage. Other streams and rivers will have rises but remain within their banks. There is some uncertainty in the rain and snow amounts through tomorrow and temperatures this weekend but confidence in river levels is good (60-80%). Additionally, water temperatures have dropped to the lower 40s, so the chances of hypothermia will be increased for anyone falling into rivers or streams.
