It’s time to break fans and frozen treats as we head towards Southern California above the maximum 10 degrees, which is expected to be up to 10 degrees across the region on Wednesday and Thursday.
The worst heat in LA County is forecast for San Fernando, Antelope and Santa Clarita Valley, where temperatures could sit and push into triple digits in the 90s, according to the National Weather Service.
People living in Downtown and East Los Angeles can expect to see highs around the ’80s to ’90s, but temperatures remain in the ’70s along the coast.
“There will be a big change tomorrow [Tuesday] And as the high pressure on Arizona expands westward, we will expand to Southern California for the rest of the week,” the Weather Service said in a Los Angeles forecast Monday night.
The weather will be even more intense in the hot empire, with the wider range of the counties of San Bernardino and Riverside, and until 8pm on Thursday. This consultation applies to cities in Corona, Moreno Valley, Ontario, Rancho Cucamonga, Riverside, San Bernardino and Fontana.
Thermal advisories are in effect at the same time in the inland areas of San Diego County, including the communities of San Marcos, El Cajon, Lamesa, Escondido, Poway and Santee.
Residents living in these areas are encouraged to drink plenty of liquids, stay in air-conditioned rooms, and see relatives and neighbors away from the sun, according to weather services.
The weather in Los Angeles is mostly expected to sit under hot advisory standards, offering hours of relief, as temperatures are relatively cool overnight in the mid- to mid-60s. Nevertheless, Angelenos recommends avoiding intense outdoor exercise and being aware of the risks of fever-related illnesses this week.
As the high-pressure system weakens, heat waves begin to break down on Friday, bringing back sea breezes and cool temperatures on land. A wider relief is forecast for the weekend when temperatures are expected to return to seasonal norms.
This week’s hot spell is expected to bring moderate fire weather. Forecasters predict a 20% chance of danger flag warnings in internal valleys, mountains and deserts.
The current model shows the possibility of even hotter heat waves, consistent with steep onshore winds, which could lead to more dangerous fire weather.
