Temperatures will soar into the triple digits throughout Riverside County Thursday as a brutal heat wave will retain the region in its grip until this weekend, according to the National Weather Service.
A high pressure system will linger over the western United States until it is replaced by a low pressure system on Saturday, keeping temperatures hot and dry through Friday in most areas, forecasters said.
The NWS issued an excessive heat warning that will last until 8 p.m. Thursday in the Riverside metropolitan area. Once that warning expires, a heat advisory will take effect in the Riverside metropolitan area and last through 8 p.m. Friday.
The Coachella Valley was not included in either advisory.
Residents are advised to drink plenty of fluids, stay in an air-conditioned room, stay out of the sun and check up on relatives and neighbors, according to the NWS. The agency also stresses that children, senior and pets must never be left in a vehicle parked in hot weather, even with windows open, as interior temperatures can rapidly turn lethal.
High temperatures Thursday are forecast to reach 111 in the Coachella Valley, 106 in the San Gorgonio Pass near Banning, 106 in Hemet, 108 in Riverside, 105 in Lake Elsinore, 104 in Temecula and 87 in Idyllwild.
Highs could reach 106 again on Friday in much of the Riverside metropolitan area, then drop to 102 on Saturday, forecasters said. The mercury in the Coachella Valley is expected to top out at 111 on Friday before dropping to 106 on Saturday.
Riverside County has 35 cooling centers available countywide with mandatory mask wearing and social distancing protocols in place.
