Two areas marked record temperatures in Los Angeles County to date, including Woodland Hills, which set a record 112 degrees on Wednesday, according to the National Weather Service. The previous record was 111, in 1998.
Burbank recorded 112 degrees, surpassing its record for the date, which was set in 2017.

The California Independent System Operator, which manages the state's power grid, has issued Flex Alerts for three consecutive days, calling on residents to voluntarily reduce their power use between 4 and 9 p.m. Friday will be the third straight day of the alerts, and Cal-ISO has warned that more are likely over the weekend.
Residents are asked to make the following adjustments under the alert:
- Set thermostats to 78 degrees or higher
- Avoid using large appliances
- Avoid charging electric vehicles
- Turn off unnecessary lights
"Lowering electricity use during that time will ease strain on the system, and prevent more drastic measures, including rotating power outages," grid operators wrote in a statement.
So far, residents have heeded the call, and the state's electrical grid has operated without any major interruptions during the beginning stages of the heat wave. If the Flex Alerts fail to result in reduced power usage and the system is strained, Cal-ISO could ultimately impose rolling power cuts.
Despite the state's recent push for residents to ditch gas-powered cars, the utility grid operator has asked residents to avoid charging their electric vehicles. The request to avoid charging such vehicles comes days after the state announced plans to ban the sale of gas-powered cars by 2035.
If weather or grid conditions worsen, grid operators said they may issue a series of emergency notifications to access additional resources.
"We will be seeing dangerously warm temperatures this weekend," the National Weather Service tweeted out of its Bay Area office.
In what’s forecast to be the most extensive heat wave in California this year, temperatures in Northern California are expected to be 10-20 degrees warmer than normal through next week. In Southern California, temperatures are expected to climb 10-18 degrees warmer than usual.
"An extended period of dangerous heat will impact much of our area over the holiday weekend and into early next week. All populations will be at risk for heat-related illnesses. Drink plenty of water, seek air conditioning, and avoid outdoor activities during the day," NWS officials said.
