LOS ANGELES (CNS) – A heat advisory went into effect Wednesday for the Los Angeles inland coastal area, while another advisory remained in effect for valley and mountain communities where temperatures were expected to reach as high as 105 degrees.
The advisory for the Los Angeles inland coastal area, including downtown Los Angeles, will be in effect until 8 p.m. Friday, with temperatures of up to 94 degrees possible, according to the National Weather Service.
A separate heat advisory has been in effect since Tuesday for the Santa Clarita, San Fernando and San Gabriel valleys, along with the San Gabriel Mountains and the Antelope Valley (14) Freeway corridor. The heat advisory will remain in place until 8 p.m. Friday.
Forecasters noted that while the heat advisory took effect Tuesday, “the peak of the heat for most areas will be Wednesday and Thursday.”
The higher temperatures are the result of a weakened onshore flow, which is reducing the morning and evening cloud cover in most of the area, forecasters said.
“There is a high risk for heat illness for sensitive populations including the very young, the very old, those without air conditioning, and those active outdoors,” according to the NWS.
Forecasters said little change is expected Thursday, with temperatures remaining similar in most areas. Mountain and interior communities could warm by another degree or two, while the coast may cool slightly because of a stronger afternoon sea breeze.
Temperatures are expected to ease slightly Friday, although forecasters warned that some heat advisories and warnings could be extended if conditions persist.
Looking ahead, increasing monsoonal moisture could bring a chance of showers and thunderstorms to the mountain areas beginning Sunday and continuing into next week, according to the weather service.
