It was a blistering three-day weekend in Southern California, where at least two record high temperatures were recorded.
Sunday's high in Woodland Hills hit 121 degrees, marking the "highest official temperature ever recorded in L.A. County," the National Weather Service reported. It tops the previous record holder, 119 degrees, which was set in 2006, according to the agency.
It was only a little cooler in San Luis Obispo County, where the mercury climbed to 117 degrees, which is also a record. And Burbank set its own record with 114 degrees on Saturday.
“The very hot conditions through Labor Day will bring an increased threat of large fire activity including fires with large vertical growth,” NWS forecasters wrote on Twitter.
And on Saturday, the record heatwave even claimed the life of a Los Angeles area woman...
The woman, whose name has not been released, was hiking with a friend outside of Calabasas on Saturday when she started feeling ill and suddenly collapsed, says Los Angeles County Sheriff’s Deputy Juanita Navarro. She died after being transported to a local hospital, Navarro adds.
The woman's death was among dozens of heat-related incidents that occurred in Southern California over the weekend as temperatures in some areas broke records by hitting 121 degrees.
"This kind of heat can be life-threatening and people are urged to use common sense, keep hydrated and stay out of the heat and in air-conditioned locations as much as possible,'' the National Weather Service advised.
Temperatures in the state are expected to remain between 105 and 115 degrees through the middle of the week, meteorologists say.
