The National Weather Service Wednesday issued an excessive heat watch, warning of “dangerously hot conditions” and elevated critical fire-weather between Friday and Monday during the region’s latest heat wave.
“Extreme heat will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities,” the weather service warned in announcing the excessive heat watch, which will be in effect from Friday morning through Monday evening.
It said the “dangerously hot conditions” would include highs of 108 degrees in some L.A. County valley areas.
The heat watch will cover all of L.A. County, including the Antelope Valley, which is often excluded from such warnings because high heat is common there, and inland Orange County.
During the heat wave, the night will not provide much relief because temperatures will remain in the 70s and 80s, according to the NWS.
“Extreme heat will significantly increase the potential for heat-related illnesses, particularly for those working or participating in outdoor activities,” warned the NWS.
“Be prepared to drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Take extra precautions if you work or spend time outside.”
The weather service also stressed that “young children and pets should never be left unattended in vehicles under any circumstances. This is especially true during warm or hot weather, when car interiors can reach lethal temperatures in a matter of minutes.” The warning also applies to seniors.
The weather Service forecast sunny skies in L.A. County Wednesday and partly cloudy skies closer to the coast, along with highs of 72 degrees at LAX; 74 in Avalon; 81 in Long Beach; 82 in Downtown L.A.; 84 on Mount Wilson; 92 in San Gabriel; 94 in Burbank; 95 in Pasadena; 98 in Saugus; 100 in Woodland Hills; and 102 in Palmdale and Lancaster. Highs of 108 are forecast in Woodland Hills Friday and Saturday and in Palmdale and Lancaster on Saturday.
Sunny skies were forecast in Orange County Wednesday, along with highs of 75 in Laguna Beach and San Clemente; 76 in Newport Beach; 82 on Santiago Peak; 86 on Ortega Highway at 2,600 feet; 87 at Fremont Canyon and in Irvine; 88 in Fullerton; 89 in Anaheim and Yorba Linda; and 91 in Trabuco Canyon, which will reach a high of 98 on Friday. Several Orange County areas will be in the 90s this week, but not quite as Trabuco Canyon on Friday.
