After beginning at 1 p.m., the warning was set to last until 8 p.m. Sunday, according to the National Weather Service. During the dayslong heat wave, afternoon highs will likely reach 100 degrees or higher in many lower-elevation areas across Los Angeles and Ventura counties, the agency said.

With high pressure building over the region, temperatures were forecast to range from 85 to 95 degrees in the inland coastal areas and 100 to 108 degrees in the valleys and deserts.

Relief from the sizzling conditions might begin with "several degrees of cooling" on Monday, according to the Weather Service, with slightly lower temperatures through Wednesday.

With the sweltering days comes the risk of heat-related illnesses, especially among children, the elderly and pets without adequate shelter, officials said.

“Never, ever, leave people or pets in enclosed vehicles, even for a short period of time,” the Weather Service said in a statement.

The Humane Society, on its website, shared tips for keeping animals safe amid soaring temperatures. Tips for pet owners include: Don't rely on a fan, provide ample shade and water, watch the humidity, and cool your pets inside and out.

Those who work or spend time outdoors were admonished to reschedule strenuous activities to early morning or evening hours, and to know the symptoms of heat exhaustion and heat stroke.

The agency encouraged Southland residents to wear lightweight and loose-fitting clothing when possible and drink plenty of water.
