The heat wave that has scorched the region with triple-digit temperatures is only expected to ease slightly today, according to the National Weather Service (NWS).
Monsoonal moisture will again bring scattered afternoon and early evening thunderstorms to the mountain and desert areas of San Diego County, as another day of hot and humid weather blankets the region.
“By the end of, not this week, but the following week, we ought to start cooling off just a bit. As the pattern seems to be shifting just a little bit that would be a little bit more favorable for cooler conditions,” said Roger Pierce, NWS meteorologist.
The hot conditions promoted another Flex Alert, urging residents to conserve energy.
Steven Greenlee, spokesperson for California Independent System Operator said the long-term loss of the San Onofre power plant has other plants working overtime, causing some equipment failures.
"Last week we lost the 775-megawatt Ormond Beach Plant and I believe [Monday] morning we also had another 500-megawatt plant that has gone down," said Greenlee.
Greenlee said they’re expecting to reach record-breaking power use of more than 47,500 megawatts on Tuesday.
Consumers were responsive to the two-day Flex alert last week and saved nearly 1,000 megawatts of energy both days, said Greenlee.
An excessive heat warning remains in effect until 9 p.m. for desert areas, where the NWS forecast daytime highs of 110 to 118 degrees and overnight lows between 86 and 94 degrees.
Daytime highs along the coast today are expected to be in the high 80s, while temperatures should peak in the high 80s to high 90s in the inland Valleys.
