LOS ANGELES -- Three days after a heat wave brought record-setting temperatures to Los Angeles, thousands of residents remain without power and authorities are asking people to limit their electricity use.
As of 6 p.m. local time (9 p.m. ET) Sunday, 26,500 people were still without power in the Los Angeles due to high demand, Los Angeles Department of Water and Power (LADWP) said in a release.
Crews had restored power to 57,000 customers since Friday's heat storm began, it said.
LADWP said that "continued overloading of circuits has slowed the restoration progress and led to recurring outages in some neighborhoods."
It asked that customers reduce their electricity use in the afternoon and evening hours, and refrain from using appliances like clothes washers and dryers until 9 p.m.
Residents could expect their power cuts to last 24-48 hours, LADWP said.
A high of 92 degrees is forecast for Monday and then dropping into the 80s for most of the rest of the week.
Scorching heat descended upon California and parts of the southwest after a heat wave swept across Canada earlier in the week, killing dozens in the province of Quebec, according to Canadian health officials.
Many areas in California on Friday broke their daily high temperature records, according to CNN meteorologists. Downtown Los Angeles reached a high of 108 degrees, breaking its previous daily record of 94 degrees, which was set in 1992.
UCLA also broke its previous daily temperature record, where thermometers read 111 degrees.
The peak energy demand level on Friday was 6,256 megawatts, LADWP said, a new record for a day in July, beating out the previous record of 6,165 megawatts, set on July 24, 2006.
The heat is also exacerbating conditions fueling wildfires in California, which have claimed one life and forced hundreds to evacuate from their homes.
