LOS ANGELES (CBS) — Thousands of utility customers across the Southland were left without power this weekend as a result of rain and thunderstorms.

Southern California Edison reported on its Twitter page Sunday that power has been restored to more than 9,000 customers.

As of 8:30 a.m., crews continued to work to restore electricity to 5,228 customers.

The hardest hit areas included Santa Ana, Oxnard, Malibu, Lake Arrowhead, Thousand Oaks and Camarillo, according to KNX 1070′s Kim Marriner.

In total, an estimated 14,188 SCE customers were affected by the outages due to the rain.

Meantime, the Los Angeles Department of Water and Power says the storm caused outages to about 1,800 customers in Mission Hills and the Vermont Square area of South Los Angeles.

Along with the rain, winds have been creating additional problems for crews hard at work.

Although the winds are expected to diminish sometime Sunday morning, they’re forecast to increase in strength later in the day, Marriner said.

Meantime, power company officials urge the public to stay clear of downed power lines.
