Temperatures will climb a few degrees Wednesday amid a heat wave afflicting parts of the Southland and raising fears of wildfires and heat-related illnesses.
The National Weather Service says in a statement that an “extended period of hot and dry weather conditions” will affect areas away from the coast “through at least early next week,” with temperatures rising daily because of a weak offshore flow. … This prolonged heat wave will likely bring moderate heat risk to those sensitive to heat.
Temperatures Wednesday will climb a few degrees — 2 degrees in Downtown L.A. but 5 degrees in Woodland Hills — with no real chance of heat records being set until Saturday, when, in Lancaster, the record of 105 degrees for a June 17 is expected to be topped by one degree, forecasters said.
In the meantime, Wednesday’s highs will be 11 degrees above normal in Woodland Hills, 10 degrees in Burbank, 5 degrees in Lancaster, 8 degrees in Downtown, and 4 degrees above normal in San Gabriel, said NWS meteorologist Curt Kaplan.
Two factors mainly account for the heat wave, he said. First, a trough of cool air that had been parked over the region is being pushed eastward and replaced by an upper ridge of high pressure, he said. Next, is the advent of weak northeast offshore winds, although they are not regarded as Santa Anas.
In this climate, overnight temperatures will be high as well, according to the NWS statement, and “the extended period of hot and dry conditions along with drying fuels (vegetation) will bring elevated fire danger to interior sections of southwest California through at least early next week” and “moderate heat risk to those sensitive to heat, especially those without effective cooling or adequate hydration.”
Forecasters urged Southland residents to limit how much time they spend in the sun, drink plenty of water, keep themselves and their children cool, check on friends and neighbors — especially seniors — and never, ever leave kids, seniors or pets in parked cars with the windows closed.
The NWS forecast sunny skies Wednesday and highs of 75 at LAX; 78 in Avalon; 83 on Mount Wilson; 85 in Long Beach and in Downtown L.A.; 90 in San Gabriel and Burbank; 91 in Pasadena; 94 in Saugus; and 95 in Lancaster, Palmdale and Woodland Hills. Temperatures will increase daily, surpassing the 100 mark in the San Fernando and Antelope valleys on Friday.
Sunny skies were also forecast in Orange County, along with highs of 70 in Laguna Beach and San Clemente; 73 in Newport Beach; 86 in Irvine; 88 in Anaheim and Mission Viejo;and 89 in Fullerton; and 90 in Yorba Linda.
