Summer temperatures will heat up across Southern California this week, with a heat advisory for all but some coastal areas in effect from Tuesday morning through at least Thursday evening.
Wednesday and Thursday are expected to see the worst of the heat, with highs in the low- to mid-90s in most valley areas and the triple digits in part of the Antelope Valley, according to the National Weather Service.
“While temperatures may be borderline across parts of the advisory area on Tuesday, temperatures will peak out Wednesday and Thursday afternoons, and additional areas may eventually need to be added to the current heat advisory,” the NWS said Sunday.
Monday’s temperatures will be reasonably mild, with a gradual increase expected to start Tuesday. A high of 80 is expected in downtown Los Angeles on Tuesday, increasing to 82 and 83 Wednesday and Thursday. In the high desert, Lancaster is expected to reach 101 and 103 degrees Wednesday and Thursday, forecasters said.
Overnight lows are also expected to be warmed than they’ve been in several months, in keeping with the progression of summer. Lows in downtown Los Angeles will be around 63 Sunday and Monday, increasing to 65 Thursday and 67 by next weekend.
Forecasters also warned of a “significant warming and drying trend through next week, with widespread elevated to brief critical fire weather conditions Tuesday through Thursday.”
The Los Angeles County Department of Public Health urged residents to take precautions to avoid heat-related illness. The department issued the following recommendations:
— Drink plenty of water and keep hydrated throughout the day.
— If you must go out, plan your day to avoid going out during the hottest hours, and wear sunscreen.
— Wear lightweight, light-colored clothes, and wear a hat or use an umbrella.
— Cars get very hot inside, even if the windows are cracked or open. Never leave children or pets alone in cars. Call 911 immediately if you see a child or pet in a car alone.
— Check on those at risk for heat-related illness, like those who are sick or have chronic conditions, older adults, pregnant women, children, those who live alone, pets and outdoor workers and athletes.
