Excessive Heat Warning Issued In Montrose-La Crescenta

MONTROSE-LA CRESCENTA, CA – An excessive heat warning will go into effect across the Southland Monday morning, scheduled to last through Thursday. The four-day period of sweltering weather will increase the threat of heat-related illnesses, especially among young children and the elderly, those participating in outdoor activities, and to those without access to air conditioning, according to a National Weather Service statement. It will also create an increased potential for power outages because of the widespread use of air-conditioning.

Daytime high temperatures will range from 85-92 degrees on the Westside and up to 92-100 degrees inland, with the hottest days expected to be Tuesday and Wednesday, the statement warned. Overnight low temperatures will offer little reprieve from the heat, ranging from 66-76 degrees.

Southern California residents were urged to take steps to protect themselves from the conditions, scheduling strenuous activities for the coolest part of the day – in the morning or evening – wearing lightweight and light-colored clothing and drinking plenty of water.

Forecasters 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 covers seniors.

The excessive heat warning will be in force along the L.A. County coast, in beach cities, metropolitan Los Angeles, Downtown L.A., and the Hollywood Hills; the San Gabriel, San Fernando, Santa Clarita and Antelope valleys; the San Gabriel and Santa Monica mountains; and inland Orange County, where highs will range from the mid 90s to 104.

Forecasters also warned of an elevated danger of fire, but no further south than Santa Barbara County.

Also in effect Monday is a high surf advisory scheduled to expire in L.A. County at 8 p.m. and in Orange County at 9 p.m.

In Orange County, forecasters expect surf of 5-8 feet along with occasional 10-foot sets.

The NWS forecast sunny weather in L.A. County Monday and highs of 83 degrees in Avalon and at LAX; 89 in Long Beach; 91 on Mount Wilson; 92 in Downtown L.A.; 97 in San Gabriel; 98 in Burbank; 99 in Pasadena; 103 in Saugus; 104 in Lancaster; and 105 in Palmdale and Woodland Hills.

Temperatures will continue rising this week but begin a slow cooling trend on Friday.
