SPOKANE, Wash.—Weather left more than 4,000 Avista customers without power across northeastern Washington Wednesday morning.

Avista’s website said the outages were reported overnight and into Wednesday morning.

Avista officials reported the estimated restoration time ranged anywhere from early Wednesday morning to after midnight Thursday.

Avista representative Sandra Hoye said the restoration times are varying so much because there were many different kinds of repairs being made by Avista crews.

Late Wednesday morning, the company sent out a release that said customers in Gifford, Hunters, Fruitland, Two Rivers, Inchelium and the surrounding areas are experiencing a "prolonged power outage."

Officials said a tree had come into contact with a transmission line, which caused additional equipment failure in the Gifford substation.

Crews removed the tree, Avista officials said, and are currently assessing the damage. They estimated 2,000 people in that area will be without power until at least Thursday morning.
