Record-breaking temperatures roasted the Southland Friday as a heat wave settled over the region, bringing with it potentially life-threatening conditions that could be matched or even worsen Saturday.

“Dangerous and potentially life-threatening heat is expected through Saturday, when high temperatures between 100 and 110 degrees are expected for many interior sections of southwest California,” according to the National Weather Service.

The weather service attributed the heat wave to a “strong upper-level high-pressure system centered over the desert southwest” which is expected to strengthen and expand westward through Saturday. There is a chance the heat wave will continue into Sunday, especially away from the coast, according to the NWS.

A variety of temperature records were tied or broken by mid-afternoon. Woodland Hills reached a high of 109 degrees, breaking the record of 108 set for the date in 2006. Sandberg reached a record of 98 degrees, besting the mark set for the date in 1989. Downtown Los Angeles tied the 1954 record of 96 degrees, while Lancaster Fox Field tied the 1989 record of 110.

An excessive heat warning that had been scheduled to expire at 9 p.m. Saturday was extended to 11 p.m. Saturday for the Los Angeles County Mountains, Santa Monica Mountains Recreation Area, Santa Clarita Valley, San Fernando Valley, San Gabriel Valley, Antelope Valley and the Los Angeles coastal area, including downtown Los Angeles.

Daytime temperatures in the Antelope Valley are expected to range from 102 to 112 degrees, with overnight lows dipping only into the 70s and 80s.

“Hot temperatures will create a dangerous situation in which there is an increased threat of heat-related illnesses. The extended heat wave will also bring elevated fire weather conditions through the weekend,” according to the NWS.

NWS forecasters again warned area residents to protect themselves and their loved ones from the sweltering heat. People who work outdoors should confine strenuous activities to the early morning or the evening hours, wear lightweight clothing, take frequent breaks, and drink plenty of water. Residents should also check on friends and neighbors and must never leave children, seniors or pets in parked vehicles in hot weather.

“Temperatures inside vehicles, even if the windows are partially open can quickly rise to life-threatening levels,” the statement warned.
