A heat advisory was in effect Tuesday for Los Angeles-area valley and mountain communities as temperatures continued a slow climb toward the triple-digits, prompting warnings for residents to prepare for the sweltering conditions.
Forecasters said “potentially dangerous heat” could develop in areas away from the immediate coast.
A heat advisory took effect at 10 a.m. Tuesday and will remain in place until 8 p.m. Friday for the Santa Clarita, San Fernando and San Gabriel valleys, along with the San Gabriel Mountains and the Antelope Valley (14) Freeway corridor. National Weather Service forecasters said those areas could see temperatures as high as 105 degrees.
Forecasters noted that while the heat advisory took effect Tuesday, “the peak of the heat for most areas will be Wednesday and Thursday.” Tuesday temperatures were expected to be 2 to 5 degrees higher than Monday.
The Los Angeles inland coastal area, including downtown Los Angeles, will be under a heat advisory from 10 a.m. Wednesday through 8 p.m. Friday, with temperatures of up to 94 degrees possible.
Forecasters said the higher temperatures are thanks to a weakened onshore flow reducing the morning and evening cloud cover in most of the area.
“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.
The Los Angeles County Department of Public Health continued to urge 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.
