Temps Surge, Excessive Heat Warning Issued for Deserts

Another burst of hot temperatures is expected on Wednesday, prompting the National Weather Service to issue an excessive heat warning for Southern California deserts. 

The warning will go into effect at 11 a.m. Wednesday and last until 8 p.m. During that time, high temperatures in the Borrego Springs desert are expected to be between 114 and 118 degrees, the NWS said.

High temperatures elsewhere are expected to be in the low-90s for the inland valleys and mountains, and in the mid- to high-80s along the coast. 

A heat warning is issued when dangerous heat is expected. Prolonged hot temperatures could lead to heat illness and, in some cases, heat stroke.

The NWS says during periods of high heat, people should never leave children or pets alone in hot vehicles; limit sun exposure by taking plenty of breaks when working outside, should stay hydrated and should check on others who may be affected by the heat.

San Diego County provides dozens of "cool zones" where residents can get out of the sun and into an air-conditioned room. For a list of locations, visit here.
