A deep marine layer is expected to bring cooler temperatures to the Southland Monday … but the highs will still be above normal by at least 5 degrees, according to the National Weather Service.
Monday’s temperatures are expected to be closer to normal before warming up to potentially dangerous levels again Wednesday and Thursday.
“Coastal areas will be much cooler with continued night through morning low clouds and fog,” the NWS said. “A cooling trend will start Sunday but another heat wave is expected by the middle of next week.”
On Saturday, temperatures topped 90 degrees in many parts of Los Angeles County and surpassed 100 in the Antelope Valley. Temperatures reached 102 degrees in Lancaster on Saturday and 101 in nearby Palmdale.
The high Saturday in downtown Los Angeles reached 82, while Burbank saw a high of 90 and it was 88 in Pasadena.
The first signs of excessive heat showed up Thursday with triple-digit highs in some areas. Excessive heat warnings kicked in Friday.
As usual during heat waves, forecasters urged people to drink plenty of fluids, seek out air conditioned spaces and check in on vulnerable relatives and neighbors.
“Extreme heat will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities,” according to the NWS.
“Young children and pets should never be left unattended in vehicles under any circumstances. This is especially true during warm or hot weather when car interiors can reach lethal temperatures in a matter of minutes.”
