Heatwave Cooks Lake Forest

LOS ANGELES, CA — A heat wave washed over the Southland Friday, sending temperatures into triple-digit territory in some valley communities and bring 90-degree heat to much of inland Orange County. Such high temperatures can post a threat to human health officials warned. The threat prompted authorities to open up cooling center across the Southland as authorities strove to balance the risk of heat stroke with the coronavirus outbreak.

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 Saturday morning to 8 Sunday night in inland Orange County and the Santa Ana mountains.

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 light-weight clothing.

And, it stressed, "never, ever, leave children, elderly and pets in and enclosed car, even with the windows down during this heat."

Sunday will be the heat wave's warmest day. Temperatures in the 90s in some valley areas will last at least through Thursday.

Sunny skies were forecast in Orange County, along with highs of 74 in San Clemente; 76 in Newport Beach and Laguna Beach; 83 on Santiago Peak; 87 at Fremont Canyon and on Ortega Highway at 2,600 feet; 88 in Irvine; 89 in Mission Viejo; 90 in Yorba Linda and Fullerton; and 91 at Trabuco Canyon and in Anaheim. A cooling trend is expected Monday.
