Thousands Still Powerless in Southern California City

Commuters dealt with dead traffic signals and several businesses were forced to remain closed as crews worked to restore power to thousands in downtown Long Beach, Calif. following three separate fires in underground electrical vaults.

Southern California Edison says some 2,500 residences and businesses remain without electricity Friday morning. There was no indication of when service would be restored.

The underground fires, which sent at least manhole cover airborne, were doused shortly after being reported Wednesday afternoon. No injuries were reported.

The fires initially cut power to around 4,800 customers. The Aquarium of the Pacific was forced to close for the day because it had no electricity.

The city is providing flashlights and water for affected residents.
