Neah Bay, Clallam Bay and Sekiu were without power for almost three hours Tuesday night.
The outage was caused by a tree limb falling on a power line near Milepost 15 on state Highway 112 in the Falls Creek area near Sekiu, according to Mike Howe, Clallam County Public Utility District spokesman.
About 1,500 customers were affected, Howe said.
The outage began just before 7 p.m. PUD crews restored power at 9:40 p.m.
