A heat wave is coming to Southern California, with near-record temperatures expected early this week, according to the National Weather Service.
An Excessive Heat Warning has been issued for the San Diego County valleys from 10 a.m. Monday through 8 p.m. Tuesday, with dangerously hot conditions, forecasters said.
Temperatures expected to range between 95 and 107 degrees in San Diego County valley areas, including Escondido, El Cajon, San Marcos, La Mesa, Santee and Poway.
The deserts could get as high as 116 degrees Monday and 117 on Tuesday.
Extreme heat will significantly increase the potential for heat-related illnesses, particularly for those working or participating in outdoor activities.
The weather service advises drinking plenty of fluids, staying in an air-conditioned room, staying out of the sun and checking up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances.
Residents were urged to learn the signs and symptoms of heat exhaustion and heat stroke, and to wear lightweight, loose-fitting clothing when possible.
The heat won’t last for too long, forecasters said, as cooler temperatures are expected Wednesday through the rest of the week.
“A trough over the Pacific Northwest will deepen into California by later this week,” the weather service said. “This will lower temperatures back to average readings by Thursday with triple-digit heat only expected across the lower deserts.”
The marine layer will deepen, bringing back low clouds near the coast each night and morning.
