The National Weather Service issued an alert that high temperatures "will reach dangerous levels across much of Southern California this week,'' and will be very hot every day through early next week. In many locations across the Los Angeles and Ventura Country valleys, temperatures will hit between 102 to 108 degrees, the worst heat will be in the afternoons, but the nights won't be much cooler - they "will not allow for much relief,'' says the NWS.
According to L.A. Curbed, this brutal Los Angeles heatwave is the fault of "high pressure aloft and weak offshore flow,'' meaning high pressure up above the entire region and thin winds off the ocean. The humidity is caused by "lingering moisture from Hurricane Linda,'' according to City News Service. Linda is whirling around the Pacific of the Baja peninsula and is expected to bring some thunderstorms to inland Southern California.
The NWS has issued a warning about rip currents and high surf on the coast, plus "sneaker waves,'' all caused by a "long-period swell in the Pacific,'' an extra reminder for powerless victims on the natural world.
Daily News said that temperatures and humidity levels rose to uncomfortable levels in the Southland as the heat wave is expected to last until early next week. Perilous conditions characterized by strong rip currents and high surf will prevail along the coast until Tuesday night. The high heat is being attributed to high pressure developing over the region, combined with the weak winds blowing in from the ocean.
"The combination of high pressure aloft and weak offshore flow will bring very hot weather to much of Southwestern California ...," "Maximum temperatures will reach dangerous levels across much of Southern California this week," according to the National Weather Services.
The brutal weather conditions prompted the NWS to issue an excessive heat warning for the San Gabriel and Santa Monica mountains in both Los Angeles and Ventura counties, with highs of 105 expected at low elevations.
