A new week, a new month, a new heat wave – the hottest so far this year.
The National Weather Service has issued an excessive heat warning for much of Southern California as temperatures are expected to be in the triple digits this week and through Labor Day weekend.
This week’s excessive heat for the region will be the warmest and longest heatwave so far this summer, said David Sweet, a forecaster for the National Weather Service in Oxnard, adding that record temperatures are a possibility.
Meteorologists predict temperatures will start to rise on Wednesday and run through Sunday, with mountains, valleys and deserts in Los Angeles and Ventura counties expected to reach 100 degrees or warmer. Woodland Hills could hit 110 degrees and Burbank could hit 104 degrees on Thursday. Lancaster in Antelope Valley could reach 110 degrees.
Temperatures are expected to rise again on Thursday and Sunday.
Temperatures between 70 and 80 degrees are expected on the coast. Temperatures in downtown Los Angeles could range from 90 to 95 degrees Wednesday through Sunday, with 93 degrees expected for Thursday and 95 degrees for Sunday.
Meteorologists also expect lower humidity over the next few days, which combined with extreme heat and dry vegetation increases the risk of fire.
Temperatures could reach over 100 degrees in parts of Orange County, particularly in areas along the 5 Freeway, which stretches east, said Brandt Maxwell, a weather forecaster with the National Weather Service in San Diego. Temperatures are expected to be above 100 throughout the Inland Empire, Maxwell said.
“The question is how high it can go,” Maxwell said.
Despite the heatwaves that swept the western United States this summer, the coast has stayed cooler because it’s been protected by a layer of ocean, Brandt said. Temperatures in many coastal areas have largely stayed below 90 degrees.
“That should change this week,” said Brandt.
Heat waves are fairly common in early September, with high records at this time of year, Brandt said. Early next week is the most likely time for new records to be set, although there could be some isolated records for this week, he added.
Excessive heat warnings indicate that extreme heat is to be expected in certain areas, which could lead to more frequent incidents of heat illness. People are advised to minimize their exposure to the outside heat, drink plenty of water and stay in air-conditioned spaces whenever possible.
