ESFPDT Synopsis: Rain and high mountain snow this weekend and early next week will lead to rising water levels on area streams and rivers. Total rainfall amounts of 2 to 5 inches are expected in the Cascades and 1 to 3 inches in the eastern Oregon mountains. In addition, temperatures rising to the 40s and lower 50s in the mountains will lead to snow melt adding even more water to area rivers and streams. What: Precipitation and snow melt due to warmer temperatures this weekend into early next week will lead to rises on area creeks, streams and rivers. Many rivers are forecast to reach near or above bankdfull by Sunday, including the Walla Walla River at Touchet, the Klickitat River at Pitt, the John Day River at Service Creek, the Umatilla River at Gibbon, and the Naches River at Cliffdell. Another concern will be rapid rises on smaller streams and creeks due to heavier downpours and snowmelt. This could lead to debris flows on recent burn scars and over steep terrain. When: Rain will continue through Monday with the heaviest rain expected tonight and Sunday. Where: The East Slopes of the Washington and Oregon Cascades, the Simcoe Highlands, the Northern and Southern Blue Mountains, the Blue Mountain Foothills of Washington and Oregon, Wallowa County and the Grande Ronde Valley. This Hydrologic Outlook will be updated as needed due to changing conditions.
