San Diego County Desert Temps Up To 10 Degrees Above Average

Temperatures are expected to soar up to 10 degrees above average Wednesday in the deserts of San Diego County.

A National Weather Service heat advisory for the deserts is set to remain in effect from 10 a.m. Wednesday until 8 p.m. Thursday. High temperatures are expected to be between 111 and 116 degrees Wednesday and Thursday.

"A dome of high pressure centered over the Mojave Desert will cause excessively hot weather today and continue through Thursday," according to the weather service. "Temperatures will be 5 to 10 degrees above normal in the high deserts, Coachella Valley and Anza-Borrego Desert, and could promote heat illness to those unprepared or those most at risk."

Forecasters advised those who live in or are visiting the deserts to avoid potentially serious ailments by staying hydrated and avoiding unnecessary outdoor labor. Authorities also warned against leaving children or pets in parked cars, which can quickly become death traps in high heat.
