Triple-digit temperatures are expected Tuesday in the Coachella Valley and the blazing conditions are not expected to let up until this weekend, according to the National Weather Service.
Building high pressure over Southern California will keep temperatures hot throughout Riverside County until Friday, with Wednesday and Thursday expected to be the hottest days of the week in desert areas, forecasters said.
The NWS issued an excessive heat warning that will be in effect from noon Tuesday through 7 p.m. Friday in the Coachella Valley and the San Gorgonio Pass near Banning.
High temperatures Tuesday are forecast to reach 108 in the Coachella Valley, 100 in the San Gorgonio Pass, 99 in Hemet, 96 in Riverside and Lake Elsinore, 91 in Temecula and 86 in Idyllwild.
The NWS urged residents to drink plenty of fluids, stay out of the sun and check up on relatives and neighbors. Also, young children and pets should be never be left unattended in a vehicle, with car interiors able to “reach lethal temperatures in a matter of minutes,” according to the NWS.
Nighttime lows are expected to remain in the low- to mid-70s through Friday in the Coachella Valley, meaning the minimal cooling at night could pose a health risk to those without access to air conditioning because the body needs time to cool down from the day’s heat.
The high temperatures typically trigger the opening of cooling centers, which include libraries and senior centers where people can escape the peak daytime heat. However, they were not able to be opened because of various restrictions related to the coronavirus outbreak.
Senior citizens can dial 211 to be informed of services available.
The mercury in the Coachella Valley could reach 112 on Wednesday and 109 on Thursday, forecasters said. Highs in the Riverside metropolitan area will remain in the mid- to high-90s until Friday.
