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

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.

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.

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.
