California’s latest Flex Alert will last a second day.

Cal ISO, the state's power grid regulator, issued a Flex Alert for Saturday from 4 p.m. to 9. A Flex Alert had been issued for those same times on Friday.

Officials on Friday once again asked state residents to conserve power during those hours, thanks to a major wildfire in Southern Oregon and a heat wave settling in the Bay Area and much of the state.

Gov. Gavin Newsom issued an emergency proclamation earlier Friday to free up additional capacity from the use of backup power generators.

Oregon's Bootleg Fire, which has burned nearly 39,000 acres, was threatening transmission lines and limiting how much energy could be imported into the state, Cal ISO officials said in a release.

For the second day in a row, agency officials recommended consumers close their drapes and blinds, use fans, set thermostats to 78 degrees and not use large appliances or unnecessary lights.

The Bay Area must also contend with a "Spare the Air" alert on Saturday, with air quality in the East Bay projected to be unhealthy for sensitive groups due to smog. As of Friday morning’s projections, the North Bay was the only part of the region expected to have "good" air quality.

Practically all of the Bay Area is under an excessive heat warning or a heat advisory from the National Weather Service, starting at noon Friday and running through 11 p.m. on Sunday. Some inland temperatures are projected to reach as high as 110 degrees, increasing the risk of heat-related illnesses for residents.
