Hydrologic Outlook issued April 9 at 4:36PM PDT by NWS Pendleton OR

ESFPDT Moderate rain this weekend in the Washington Cascades and northern Blue Mountains combined with snowmelt from above normal temperatures will lead to rivers rises this weekend and early next week. Most rivers are currently running low and the increased streamflows will not be a problem. However, the Naches River at Cliffdell and at Naches are expected to rise above Action Stage Saturday through Monday night. The Grande Ronde River at Troy is expected to rise above Action Stage early Monday through Tuesday. Only localized minor flooding is expected. Please monitor the latest river forecasts from the National Weather Service for additional information.
