The latest heat wave enveloping central and southern California will bring triple-digit temperatures and increased wildfire danger.
Heat advisories were issued for swaths of greater Los Angeles north into the Antelope Valley and the San Joaquin Valley starting Friday through the weekend.
Temperatures could be up to 8 degrees above normal on Saturday and Sunday. Residents are urged to drink plenty of water, avoid the sun and check on elderly relatives and neighbors.

A heat advisory will be in effect until 11 p.m. Sunday in the San Gabriels, where forecasters expect highs ranging from 95 to 103 at lower elevations and overnight lows in the 70s and lower 80s. A heat advisory will be in force from 1 p.m. Saturday to 11 p.m. Sunday in the Antelope Valley, where highs will range from 98 to 108, with overnight lows in the 70s.
A heat advisory means high temperatures and humidity levels will combine to increase the chances of heat-related illnesses, forecasters say. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors.
Additionally, forecasters said children, seniors and pets should never be left in a parked car in hot weather, even with the windows cracked open, because interior heat levels can quckly become deadly.
This weekend's heat levels in the mountains and the Antelope Valley will create "an increased threat of heat-related illness, especially to those without access to air conditioning. Power outages are possible," according to a National Weather Service statement.
