Southern California Edison says about 76,500 homes have no electricity.
The utility expects to have service restored to 99 percent of its customers by 8 p.m. Sunday.
"We understand our customers are anxious to get their lights back on, and we're continuing to ask for their patience," SCE President Ron Litzinger said in a statement released Friday. "The massive winds that hit Wednesday evening have created some of the worst damage we've seen in a decade and resulted in some of the most complicated restoration efforts in years. Thousands of trees blew over, damaging thousands of overhead wires and poles."
As of 4 p.m. Saturday, SCE said restoration of power was at 76 percent.
Customers can call SCE customer service at (800) 655-4555.
The Department of Water & Power says the number of customers still without power is down to about 1,000. Power has been restored to more than 210,000 customers since extreme winds knocked out power across Los Angeles on Wednesday night.
In Arcadia, no major injuries were reported. Signals at all but 11 intersections were restored and temporary stop signs were placed at the intersections not working.
Other areas hit hard by the winds were Pasadena and Temple City.

The gusty winds and dry conditions are behind a red flag warning for parts of Los Angeles and Ventura counties. The Los Angeles County Fire Department has about 200 extra firefighters on the job and is placing trucks in fire-prone areas due to the increased danger.
The red flag warning is in effect through 11 a.m. Sunday.
A wind advisory for the mountains and valleys is in effect through 2 p.m. Sunday.
