LADWP officials say that power was fully restored to both neighborhoods at around 7:15 p.m., more than six hours after the service was disrupted.

Metallic balloons drifted into power lines, leaving hundreds without power in the West LA communities of Sawtelle and Westwood.

More than 1.3 million people were plunged into darkness early Tuesday. Failure of an underground power line is believed to be the cause and repairs could take up to two days.

According to Silver, Avista crews identified the problem at around 9:30 a.m. and estimated that the problem will be solved by 12 p.m.

More than 3,000 people in West Los Angeles had their power knocked out Saturday afternoon, after metal balloons hit power lines. The outages were first reported in the Sawtelle and Westwood areas just after 1:30 p.
