Approximately 34,000 Avista customers are without electrical service as of Sunday morning.
Avista crews worked throughout the night to assess and begin repairs to restore power to the remaining 34,000 customers who lost power due to damage to Avista?s power grid from the severe winds and thunderstorms that passed through the area early Saturday evening.
At the height of the outage, over 48,000 Avista customers were without power.
Preliminary assessment indicates damage primarily to transmission and distribution lines.
Crews report that the majority of damage appears to have come from large tree branches coming into contact with lines.
Especially hard hit are areas in north central Spokane, Deer Park, Colbert and Colville, Wash., and Sandpoint and Priest River areas in Idaho.
Avista crews from areas not affected by the storm along with contract and mutual aide crews from Boise, Moses Lake and areas in Eastern Washington are relocating to assist crews in areas hardest hit.
Due to the extensive damage caused by the storm, restoration times are still being assessed.
