LOS ANGELES—More hot weather was on tap June 25 in parts of the Southland, but forecasters said temperatures will be slowly dropping over the next few days.
An excessive heat warning will be in place until 8 p.m. in the Antelope Valley and the Antelope Valley foothills, with temperatures of up to 105 degrees possible. A less severe heat advisory will be in effect until 8 p.m. in the Western San Gabriel Mountains and the Antelope Valley (14) Freeway corridor. Forecasters said highs could reach 100 in those areas.
According to the National Weather Service, onshore flow will result in cooling of about 4 to 8 degrees along the coast and in the valleys Tuesday, although temperatures will likely hold steady from Monday farther inland.
But the gradual cooling trend is expected to continue through midweek, “as high pressure weakens over the area and onshore flow strengthens,” forecasters said.
“By Thursday the coasts and valleys will be one to three degrees below normal—valley highs from 80-90—and the interior will be near normal,” according to the NWS.
The cooling trend will peak on Friday, with some areas seeing temperatures three to six degrees below normal, and “some beaches may not clear at all.” But that could change by Saturday.
“High pressure begins to reassert itself over the weekend,” according to the NWS. “Maximum temperatures will rise one to three degrees Saturday and two to five degrees on Sunday.”
Highs were expected in the mid-80s in downtown Los Angeles and neighboring areas Tuesday. The highs in the San Gabriel Valley are expected in the low 90s, in the mid-90s in the San Fernando Valley and Santa Clarita Valley, and 107 in the Antelope Valley.
A heat advisory issued by the Los Angeles County Department of Public Health will remain in effect through Tuesday for the Antelope Valley.
“On hot days, it’s important for everyone to both take care of themselves and check on others, especially those who have a higher chance of getting ill due to the heat. Some of them include children, the elderly, those with health conditions, pregnant people, those living alone, and pets,” Dr. Muntu Davis, Los Angeles County Health Officer, said in a statement. “Hot days can be dangerous for anyone, so it’s crucial to stay cool and hydrated.
“Never leave children, the elderly, or pets alone in hot homes, places, or vehicles,” Mr. Davis added.
The city and county of Los Angeles both operate cooling centers for people who need a place to escape the heat. To find a location, visit https://ready.lacounty.gov/heat/ or call 211.
Meanwhile, the South Coast Air Quality Management District issued a smog advisory through 7 p.m. Tuesday, covering most non-coastal areas of Los Angeles County and stretching into much of Riverside County. AQMD officials said the extreme heat will likely lead to unhealthy or worse air quality conditions in much of the area.
The AQMD urged residents to check air quality levels and limit outdoor activities, limit the use of gasoline-powered lawn and garden equipment until evening hours and conserve electricity.
