October Southern California heat wave is sticking around

LOS ANGELES — A heat advisory again will be in effect in much of Southern California Wednesday as forecasters said the region’s latest heat wave continues to pose a threat to human health and warned of an elevated risk of wildfire because of hot and dry conditions.

The advisory, which went into effect Tuesday, will be in effect until 5 p.m. Friday along the LA County coast, in Malibu, Santa Monica and other beach cities, in metropolitan Los Angeles, the Hollywood Hills, the San Gabriel and Santa Monica mountains, the San Fernando, Santa Clarita and San Gabriel valleys, and inland Orange County.

“Hot temperatures may cause heat illnesses to occur,” warned a National Weather Service statement. “Those without air conditioning will be especially vulnerable during this extended heat wave. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors.”

The NWS stressed that children, seniors and pets should never be left unattended in vehicles under any circumstances, even with windows open as car interiors can quickly turn lethally hot.

The weather service said hot and dry conditions would create an elevated risk of wildfire, but no wind advisory was in effect south of Santa Barbara County and no red flag warnings were issued.

Sunny skies were forecast in LA County Wednesday, along with highs of 81 in Avalon; 86 at LAX; 93 in Long Beach and downtown LA; 94 in Palmdale and Lancaster; 97 in San Gabriel and Burbank; 98 in Santa Clarita; 100 in Pasadena; and 102 in Woodland Hills. A cooling trend will get underway Saturday, sending temperatures down to the 70s and 80s by Monday.

Sunny skies were also forecast in Orange County, along with highs of 80 on Santiago Peak; 83 in Newport Beach and San Clemente; 84 in Laguna Beach; 88 on Ortega Highway at 2,600 feet; 91 at Fremont Canyon; 93 at Trabuco Canyon and in Yorba Linda; 94 in Fullerton and Anaheim; and 95 in Irvine. A cooling trend will begin Saturday, ushering in a return of the 80s and 70s.
