Heat wave to descend on region this week

SAN DIEGO – Southern California faces yet another heatwave this week. National Weather Service forecasters have issued an excessive heat warning from 10 a.m. Monday to 8 p.m. Tuesday, as temperatures are expected to soar as high as triple-digits everywhere except the immediate coast across a large swath of the Southland from Santa Barbara to San Diego and even stretching into Nevada.

Temperatures near the San Diego County shoreline will be in the mid-to-upper 80s Monday and Tuesday, while Monday high temperatures are expected to reach into the mid- to high 90s in locales region-wide and the 100s in Escondido, Ramona and Alpine, with temperatures a few degrees cooler on Tuesday.

A high of about 113 degrees has been predicted for Borrego Springs on

both days. The heat will start to subside midweek.

“Some monsoonal moisture will return beginning Wednesday with high

temperatures not quite as extreme,'' the NWS said.

Further north, the Santa Barbara, Ventura and Los Angeles county mountains were placed under a red flag warning from 6 p.m. tonight to 10 a.m. Tuesday, amid weather potentially ripe for wildfire.
