Scorching Weekend Temperatures Expected In Most Of San Diego County

SAN DIEGO, CA — A large swath of San Diego County remains under a heat advisory or an excessive heat warning as temperature spike amid the ongoing heatwave.

Scorching temperatures have cooked the region for more than a week and will persist through the weekend and into next week, according to the National Weather Service.

A heat advisory remains in effect for the county valleys until 8 p.m. Saturday. This includes the cities of El Cajon, Escondido, La Mesa, Poway, San Marcos and Santee. High temperatures are expected between 94 to 102 degrees, forecasters said.

An excessive heat warning remains in effect for the county deserts and mountains through the same period. This includes the communities of Borrego Springs, Julian and Pine Valley.

Dangerously hot conditions are expected in the deserts with high temperatures from 114 to 120 degrees, forecasters said. In the mountains, high temperatures are expected in the 90s to 105 degrees below 5,000 feet.

The National Weather Service warned that sweltering temperatures can increase the potential for heat-related illnesses, particularly for people working or spending time outside.

Forecasters advised people to drink plenty of fluids, stay in air-conditioned rooms, stay out of the sun, and check on relatives and neighbors. Weather officials also reminded residents that young children and pets should never be left unattended in vehicles.

"Know the signs and symptoms of heat exhaustion and heat stroke," the National Weather Service advised. "Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! Call 911."
