LOS ANGELES (CNS) – A heat wave will keep Southland temperatures soaring this weekend, reaching triple-digit territory in some L.A. County valley communities and posing a threat to human health.
The National Weather Service attributed the hot weather to a strong upper level high centered over Arizona and New Mexico. It will expand westward through Sunday before weakening somewhat on Monday.
A heat advisory issued by the National Weather Service will be in effect from 10 a.m. today to 8 p.m. Sunday in the San Fernando, San Gabriel and Santa Clarita valleys, both the San Gabriel and Santa Monica mountains, and inland Orange County and the Santa Ana mountains.
The NWS forecast temperatures of 100-110 in the Antelope Valley, 95-105 in L.A. County’s other valleys and 92-102 in the mountains and foothills.
The weather service urged area residents to stay hydrated by drinking plenty of water, confining strenuous work or exercise to early morning or evening hours, and wearing lightweight clothing.
And, it stressed,”never, ever, leave children, elderly and pets in an enclosed car, even with the windows down during this heat.”
The NWS forecast a mix of sunny and partly cloudy skies in L.A. County today and highs of 77 degrees at LAX; 86 in Avalon; 89 on Mt.
