The outage warning comes as gusty Santa Ana winds are forecast to sweep through the area, bringing an increased chance of fire danger weather with them.
The strongest winds are expected to blow on Thursday, with gusts up to 55 mph for the coasts and valley, and up to 70 mph in the mountains.
The expected strong winds, along with very dry conditions have prompted the National Weather Service to issue a red flag warning for much of L.A., Orange, San Bernardino, Riverside and Ventura counties beginning at 3 a.m. Thursday and continuing through 6 p.m. Friday.
Cal Fire has set up a preparedness website for residents at readyforwildfire.org.
Outages in Northern California were put into place beginning at midnight Wednesday with power being shut off to more than 500,000 PG&E customers. Another 300,000 were expected to lose power later in the day.
On Monday, San Jose Mayor Sam Liccardo urged residents to prepare to be without power for as long as seven days.
PG&E has previously said it is “probable” that its equipment started the 2018 Camp Fire — the state’s deadliest and most destructive blaze — when a power line touched nearby trees.
