SAN DIEGO -- Thousands of San Diego Gas & Electric customers remained without power Thursday morning after the utility shut down equipment Wednesday to prevent it from accidentally sparking a blaze.
Early Thursday, about 19,000 customers had no electricity.
By 6 p.m., power was restored to all but two customers. Find a detailed list of the affected communities here.
Forecasters said Santa Ana winds with potential to be the strongest of the season would keep gusting through Thursday evening. The winds, combined with dry weather, prompted a Red Flag Warning.
Forecasters' concerns were realized during the Red Flag period: Multiple wildfires burned around Southern California, from Chula Vista and the U.S.-Mexico border to Simi Valley, Riverside and San Bernardino.
At their peak Wednesday, the precautionary blackouts affected more than 20,000 people.
With some precautionary power shut-offs lasting more than 24 hours, the utility opened temporary aid centers where customers could get water and snacks, charge their cellphones, and get updates. Find details on the aid centers here.
In Northern California, Pacific Gas & Electric has faced steep financial penalties for its role in causing devastating wildfires, leading to widespread precautionary outages in that region this year. And in Los Angeles, officials learned the destructive Getty Fire was caused by a tree branch falling on power lines.
