Southern California is in for a blistering Labor Day weekend, with the heat expected to peak Sunday.
High temperatures combined with dry and windy conditions can bring elevated fire danger to inland regions, said the National Weather Service, which urged locals to take precautionary measures with anything that could ignite.
The agency issued a heat advisory effective Sunday for L.A. County's valleys and interior mountains, excluding the Santa Monica Mountains.
While that means the possibility of heat-related illnesses in those areas, health issues induced by scorching temperatures are likely in the Palmdale and Lancaster areas, according to the Weather Service.
"Valleys will soar into triple digits with highs ranging from 100 to 106," the agency said in a statement. "The Antelope Valley is expected to reach 108 degrees."
Downtown L.A. will see highs in the lower 90s and the coastal areas in the 70s and 80s. Hot conditions will likely linger through early next week, according to forecasters.
The county's website has a map of cooling centers available to the public.
In the Death Valley National Park, where temperatures could reach 122 degrees on Sunday, two people have died amid extreme heat in recent days.
