Westchester and Mar Vista were among the Los Angeles area communities most impacted by power outages during the record high temperatures that struck Southern California Monday, Sept. 27, according to the Los Angeles Department of Water and Power (DWP).

As of 11:30 a.m. Tuesday, Sept. 28 DWP reported that an estimated 11,775 of its 1.4 million electric customers were without power in the wake of the early fall heat wave. Westchester was atop the list of communities hardest hit with 2,411 customers facing a loss of power, over 700 more than the next highest community, Hollywood, according to DWP. Mar Vista had reported 925 customers without power.

The outages struck the utility as the thermometer in downtown Los Angeles soared to 113 degrees, the hottest temperature there since records were first kept in 1877, and other cities set records for the day.

DWP officials said the utility enlisted all available resources to respond to the heat wave, with 100 crews assigned to restore power as quickly and safely as possible.
