A prolonged and prodigious heat wave will continue to bake the San Diego area on Thursday as a second statewide Flex Alert was issued to minimize strain on the power grid.
More of the same searing conditions are in store through the Labor Day weekend, with a countywide excessive heat warning in effect through Monday evening, according to the National Weather Service.
“We are anticipating this extreme heat to be a length and duration the likes of which we haven’t experienced in some time,” Gov. Gavin Newsom said Wednesday. “Yes, we’re used to record-breaking temperatures, maybe a day or two, more episodic, but this is an extended period.”
Highs in the San Diego area on Thursday will be in the mid 80s near the coast, the lower 90s inland, the mid 90s in the western valleys, around 103 near the foothills, the upper 90s in the mountains, and 109 to 114 in the deserts.
Campo reported a record high of 105 for Aug. 31, tying the mark set in 1998.
Forecasters expect only a brief letup in the heat. “Strong high pressure centered over the Great Basin will continue the heat wave into early next week with Friday a few degrees
cooler than surrounding days for the coast and valleys,” the weather service said.
