Heat Wave To Stretch Through Friday In San Diego County​

SAN DIEGO COUNTY, CA — Temperatures could reach the triple digits Wednesday in some areas of San Diego County as a heat wave is expected to stretch through Friday.

High pressure centered over the Four Corners region will begin moving south into Arizona, bringing hot and dry conditions through Friday in most of Southern California, according to the National Weather Service.

High temperatures Wednesday are forecast to reach 84 degrees near the coast, 92 inland, 96 in the western valleys, 100 near the foothills, 102 in the mountains and 118 in the deserts, according to the National Weather Service.

Temperatures in the deserts are expected to reach 117 on Thursday, then drop to 113 on Friday, forecasters said. Temperatures in the western valleys are expected to remain in the low-to-mid-90s through Thursday, while temperatures near the foothills could reach the triple digits through Friday.

The National Weather Service issued an excessive heat warning that will last until 8 p.m. Thursday in the county's deserts.

"Extreme heat will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities," weather officials said.

Officials urged residents to drink plenty of fluids, stay out of the sun and check on relatives and neighbors. Children, seniors and pets should be never be left unattended in a vehicle, with car interiors able to "reach lethal temperatures in a matter of minutes," forecasters said.

Anyone overcome by heat should be moved to a cool and shaded location, officials advised. Call 911 immediately for heat-related illness.
