Triple-digit temperatures are expected to remain a factor in the Southland this week along with “a high risk for dangerous heat illness and fast-growing fires,” National Weather Service forecasters said Sunday.
The extreme heatwave “will continue across the region, especially the interior, through much of [this] week,” according to the NWS. “High temperatures will reach 105 to 115 across interior valleys, mountains and deserts.”
An excessive heat warning for the Golden State (5) and Antelope Valley (14) freeway corridors, the western San Gabriel Mountains and the Antelope Valley will be in effect through 9 p.m. Wednesday. Forecasters said much of that area could see temperatures of up to 116 degrees.
Another excessive heat warning will be in effect through Wednesday in the Santa Clarita Valley, the Santa Monica Mountains Recreational Area, Calabasas, San Fernando Valley and eastern San Gabriel Mountains, where temperatures up to 105 are expected.
The San Gabriel Valley will be under a less severe heat advisory until 9 p.m. Sunday, but temperatures there are still expected to reach as high as 105.
The NWS issued a red flag warning about potential critical fire danger conditions that will be in effect until 6 a.m. Monday for the western Antelope Valley foothills and the 5 Freeway corridor in northern L.A. County.
“Onshore flow will likely be on the increase … through Monday, which may lead to increasing southwest to west winds across portions of the interior and possible red flag warning extensions in some areas,” forecasters said.
“This is a dangerous situation with all the ingredients for a high risk of heat illness and fast-growing fires. Please avoid hiking in the mountains and the hills through this weekend, make plans on how you will stay cool in the afternoon and evening hours, and stay away from anything that could spark a fire.”
As always during the summer, Southland beaches will offer the most relief, with coastal areas expected to stay in the upper 70s.
The NWS outlook shows minor risk for wind and heat in ocean, coastal and valley areas through Sunday and minor risk for rip currents also through Sunday, with moderate heat in valleys Monday and heat and fire weather risks in the valleys Tuesday and Wednesday.
Forecasters said humidity levels in some areas could drop as low as 6% to 12%, combining with the heat and potential winds gusting from 25 to 40 mph, dramatically raising the risk of rapid wildfire spread if flames erupt.
Authorities reminded the public to never leave pets or children inside vehicles on days that are even a little warmer than normal, as locked cars can turn into death traps in mere minutes.
