Another heat wave is on the horizon this week in Southern California, accompanied by decreased humidity that will create elevated wildfire conditions away from the coast.
A heat advisory has been issued from 10 a.m. Tuesday to at least 8 p.m. Thursday for a wide swath of inland areas, including the San Gabriel, Santa Clarita and Antelope valleys and the western San Fernando Valley, according to the National Weather Service.
High temperatures of 92 to 105 degrees are expected, with most areas seeing peak heat on Wednesday and Thursday. Overnight lows are expected to range from the upper 60s to lower 70s at lower elevations to the mid-70s to lower 80s in the foothills and mountains.
The marine layer will help keep temperatures at immediate coastal areas moderate during the warm up.
The weather will produce widespread elevated fire weather, with “increased risk for large plume-dominated fire behavior,” according to the NWS.
“While winds aren’t expected to be of any widespread significance, the increasing northerly pressure gradient will allow for gusty north to northwest winds are likely each night across the interior mountains (especially the Grapevine),” forecasters added.
Sunday’s inland highs ranged from the mid-80s to mid-90s, and remained in the 70s near the beaches.
Monday was expected to see a widespread increase of a couple degrees before the advisory period kicks in Tuesday.
Health officials advised people to drink plenty of fluids, stay in an air-conditioned room, stay out of the sun during the hottest parts of the day and check up on relatives and neighbors.
The public was also urged to never leave children or pets in parked vehicles for even a minute, as temperatures inside vehicles can reach deadly levels in virtually no time.
