Record temperatures in SoCal's latest heat wave left many without power

In response to a power outage that affected thousands of customers in the San Fernando Valley and the extreme heat that continues to linger in the region, city officials are extending cooling center hours at some Valley locations on Sunday.

A heat advisory remains in place until 11 p.m. in the valleys and mountain areas. Sunday's valley temperatures are expected to be in the 90's, hitting triple digits in the Antelope Valley, but a few degrees cooler than Friday and Saturday's record-breaking highs.

The following cooling center facilities will be open until 10 p.m. tonight:
-- Lakeview Terrace Recreation Center, 11075 Foothill Blvd., Lake View
Terrace, (818) 899-8087;
-- North Hollywood Recreation Center, 11430 Chandler Blvd., (818) 763-7651;
-- Sherman Oaks/East Valley Adult Center, 5060 Van Nuys Blvd., Sherman
Oaks, (818) 386-9674;
-- Sepulveda Recreation Area, 8825 Kester Ave., Panorama City, (818) 893-
3700;
-- Sunland Recreation Center, 8651 Foothill Blvd., Sunland, (818) 352-5282.

The weather service attributed the heat wave to a "strong upper-level high-pressure system centered over the desert southwest" which is expected to strengthen and expand westward through Saturday. There is a chance the heat wave will continue into Sunday, especially away from the coast, according to the NWS.

A variety of temperature records were tied or broken by mid-afternoon. Woodland Hills reached a high of 109 degrees, breaking the record of 108 set for the date in 2006. Sandberg reached a record of 98 degrees, besting the mark set for the date in 1989. Downtown Los Angeles tied the 1954 record of 96 degrees, while Lancaster Fox Field tied the 1989 record of 110.

"Hot temperatures will create a dangerous situation in which there is an increased threat of heat-related illnesses. The extended heat wave will also bring elevated fire weather conditions through the weekend," according to the NWS.

NWS forecasters again warned area residents to protect themselves and their loved ones from the sweltering heat. People who work outdoors should confine strenuous activities to the early morning or the evening hours, wear lightweight clothing, take frequent breaks, and drink plenty of water.

Residents should also check on friends and neighbors and must never leave children, seniors or pets in parked vehicles in hot weather.

"Temperatures inside vehicles, even if the windows are partially open can quickly rise to life-threatening levels," the statement warned.
