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.
