The region’s dangerous heat wave entered its second week Monday, with highs again forecast to hit triple-digit territory in some L.A. County communities, and forecasters said the above-normal heat would extend into next week.
In the nearby desert resort of Palm Springs, temperatures could soar to 121 over the next couple of days.
At the same that the heat wave descends on the Southland, dense fog is making driving dangerous along the coast and in much of Los Angeles. A dense fog advisory was in force until 9 a.m. Until then, visibility will fall to a quarter-mile or less in some areas.
Officials warned residents to stay inside air conditioned rooms, if possible. The elderly, kids and pets are especially prone to heat-related dangers. And they urged drivers never to leave dogs, cats, kids or anyone in locked vehicles, even if the windows down a bit. Vehicle interiors can heat up to deadly levels quite quickly.
“Strong high pressure building across the southwestern states will cause temperatures to climb well above normal in many parts of interior southwest California today and through the middle of next week,” according to a National Weather Service statement.
The same upper ridge causing the above-average heat will cause the marine layer to become very shallow, allowing dense fog to develop, it said.
The highest temperatures this week will be between 108 and 112 degrees in the Antelope Valley.
A heat advisory will be in effect in the Los Angeles County portion of the San Gabriel Mountains until 11 a.m., when a more severe excessive heat warning will kick in, remaining in force until 9 p.m. Wednesday, according to the NWS.
In the Antelope Valley, an excessive heat warning will be in effect until 9 p.m. Wednesday. Along the L.A. County coast, in beach cities, in metropolitan L.A., the downtown area and the Hollywood Hills, a heat advisory will be in effect from 11 a.m. Tuesday to 9 p.m. Wednesday.
Also scheduled to be in effect until 9 p.m. Wednesday is a heat advisory in the Santa Monica Mountain Recreational Area and in the San Fernando, Santa Clarita and San Gabriel valleys.
“Take extra precautions if you work or spend time outside,” urged an NWS statement. “When possible, reschedule strenuous activities to ear morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose-fitting clothing when possible and drink plenty of water.”
NWS forecasters said the high temperatures are creating a high risk of heat-related illnesses. And they warned that temperatures can quickly rise to lethal levels inside parked vehicles, even with windows cracked open, meaning that children, seniors and pets must never be left in parked vehicles in high temperatures.
The NWS forecast a mix of sunny and partly cloudy skies in Los Angeles County Monday and highs of 76 at LAX; 79 in Avalon; 85 in Long Beach; 92 in Burbank and San Gabriel; 93 on Mount Wilson; 94 in Pasadena; 100 in Woodland Hills; 101 in Saugus; and 109 in Palmdale and Lancaster.
Sunny skies were forecast in Orange County, along with highs of 71 in Laguna Beach; 72 in San Clemente; 75 in Newport Beach; 87 in Anaheim and Irvine; 89 in Mission Viejo; 90 in Fullerton; and 92 in Yorba Linda.
Temperatures will remain high over the next several days, with small dips expected later in the week.
