Record-Breaking Heat Wave to Linger in SoCal, Bringing Triple-Digit Temps This Week: Forecasters

A sweltering heat wave that is forecast to bring record-breaking temperatures to parts of the Southland will likely linger through Thursday, prompting warnings in much of the region for part of the week.

Excessive heat warnings and heat advisories are in place for most of Southern California on Monday, and will last through Wednesday night, according to the National Weather Service.

Valleys, lower mountain and desert area are expected to reach highs of 100 to 111 degrees on Monday and Tuesday, the weather service’s Los Angeles office tweeted. Highs in the coastal plain, meanwhile, are forecast to reach between 85 and 103 degrees.

The sizzling heat is expected to break or tie more temperature records throughout Southern California.

On Sunday, Lancaster, Palmdale, Sandberg and Paso Robles experienced record-breaking heat for that day, according to the weather service.

Forecasters predicted record-highs in Riverside, Lake Elsinore, Newport Beach and San Diego on Monday and Tuesday.

The “dangerous” conditions have created the potential for a long duration of elevated fire danger and increased potential for power outages, according to the weather service.

Forecasters also warned of additional impacts, including “high-very high” risk for heat-related illnesses. To that end, they have urged everyone to drink plenty of water, reduce time in the sun, and stay indoors or head to a cooling center.

Do not leave children, older adults or pets in vehicles or unattended in homes without air-conditions, officials reminded the public.

“It is critically important to never leave children, elderly people or pets unattended in homes with no air conditioning and particularly in vehicles, even if the windows are ‘cracked’ or open, as temperatures inside can quickly rise to life-threatening levels,” Jeffrey Gunzenhauser, L.A. County’s interim health officer, told the Los Angeles Times.
