Continuous fires and hot temperatures that started late last week and continued over the weekend led the California Independent System Operator to issue the third statewide flex warning for Monday.

In a statement Sunday afternoon, customers were urged to conserve power between 4 and 9 pm to increase the likelihood of blackouts, citing expected demand after incidents such as the Bootleg fire that shut down transmission lines.
The system operator, which provides about 80 percent of the state’s power needs, has seen power limited to at least 3,500 megawatts.
The statement also said the operator had issued an order requiring generators to postpone planned outages for maintenance, “to ensure that all available resources can be sent to the grid.”
Residents were encouraged to start the day by pre-cooling their homes and offices and use all main appliances earlier, when solar energy will be available to supplement power consumption.
Starting with the flex warning, residents should set thermostats to 78 degrees if health allows, turn off all unnecessary light, and limit the use of appliances such as washers, dryers and dishwashers.
The National Weather Service’s meteorologist, Brayden Murdock, said many San Francisco Bay Area residents will take a break, with weather conditions requiring temperatures to drop from Monday to at least mid-week.
“Tonight we will see cooling and a very well developed marine layer,” Murdock said Sunday night.
“It’s coming back a little more than last night, not the strongest we’ve seen, but it’s going to be a well-deserved break for those in the Bay Area.”
While these temperatures will be close to normal for coastal residents, he added that the cooler trend will spread inside Monday and bring temperatures closer to normal along inland towns and villages beyond the Diablo Range, which last Wednesday and December. continue towards next weekend.
