MANHATTAN BEACH ( — An ongoing heat wave brought more triple-digit temperatures to parts of Southern California on Saturday.

Temperatures in the valleys and the Inland Expire reached the triple-digits by afternoon while downtown Los Angeles experienced temperatures in the upper 90s. Temperatures in parts of Orange County, including Anaheim and Lake Forest, were just below or at 100 degrees.

Seeking relief from the heat, many headed to the coastal communities where temperatures were in the low to mid-80s.

“Down here it’s not so bad, I guess. It’s a little warmer than usual but we’re pretty lucky,” Stuart Johnson, a Manhattan Beach resident, told CBS2’s Joy Benedict.

Meantime, health officials urged residents — especially the young and elderly who are more susceptible to heat-related illnesses — to take added precautions, including drinking plenty of water.

The heat is expected to break by Monday and will be noticeably cooler by Tuesday of next week. Click here for a list of cooling centers.

Goldberg said that thunderstorm and showers were possible for Palm Springs, Idyllwild, the San Jacinto Mountain range, Lake Elsinore, Riverside and the high desert region.
