WALLA WALLA -- The National Weather Service has issued a flood watch for the region through Sunday. Gusty winds are also in the forecast today.
Small stream flooding may be possible as several rounds of heavy rain move across the Blue Mountains and Wallowa County. Amounts of one-half to one inch can be expected today through Saturday with snow levels rising to near 7,500 feet on Saturday.
The combination of rain and melting snow will increase runoff with significant rises expected on streams and rivers starting today. High water conditions are expected on many rivers, but large rivers including the Walla Walla, Grande Ronde, Umatilla and John Day are not expected to reach flood stage.
In Oregon, the flood watch includes the foothills of the northern Blue Mountains, the Grande Ronde valley, the John Day basin and the northern and southern Blue Mountains of Wallowa county. In Southeastern Washington areas affected are the foothills of the Blue Mountains and northwest Blue Mountains.
