High temperatures will make for another warmer-than-usual weekend across the Southland, but forecasters said a deeper-than-expected marine layer will keep temperatures lower than expected in coastal and lower-elevation areas.
Still, the heat will reach potentially dangerous levels in some inland areas, where excessive heat warnings will remain in place.
An excessive heat warning will be in effect until 10 p.m. Wednesday in the Antelope Valley, Antelope Valley foothills, the San Gabriel Mountains and the 5 and 14 freeway corridors. National Weather Service forecasters said those areas could see temperatures as high as 106 degrees, creating “dangerously hot conditions.”
“There is a high risk for dangerous heat illness for anyone, especially for the very young, the very old, those without air conditioning, and those active outdoors,” forecasters said.
An excessive heat warning that was issued earlier for the Santa Clarita Valley and western San Fernando Valley has been canceled, but forecasters warned that “temperatures will still be above normal.” A heat advisory for the eastern San Fernando Valley and the San Gabriel Valley was also canceled.
An excessive heat watch that had been in place for the weekend in the Santa Monica Mountains Recreational Area was canceled and replaced with a less severe heat advisory, which will be in effect until 10 a.m. Sunday. Mountain temperatures could reach up to 98 degrees, according to the NWS. But the excessive heat watch will then take effect for the area and continue until Wednesday evening, with highs possible up to 103 degrees.
According to the NWS, the sudden changes to the forecast were prompted by a marine layer that “has refused to budge and remains at around 1,200 feet.”
“This is creating a significant moderating effect for the coastal valleys and highs there, while warmer than yesterday, should only top out in the 90s to lower 100s,” forecasters said. “Still 4-8 degrees above normal but not really worthy of any heat hazards. Higher up in elevation above the marine layer, including the Santa Monicas, and farther inland across the interior temperatures are still quite hot and a mix of heat advisories and warnings are still in effect.
“Some additional warming is expected across Antelope Valley, though chances for reaching 110 are under 10% at least through early next week.”
