Record-Setting Heat Grips Southern California

Triple-digit heat is likely again Monday as the Southern California heat wave continues

Record-setting temperatures are possible Monday as a heat wave tightens its grip on Southern California.

Triple-digit heat is likely again Monday afternoon across a widespread part of the region, prompting a request that residents watch their power usage to prevent excessive strain on the state's power grid. Cal-ISO, the state's independent grid system operator, said a Flex Alert will go be in effect until Monday evening. 

The alert comes during what is expected to be the hottest day of the heat wave that began Saturday, with the warmest temperatures ranging between 100 and more than 120 degrees.

Power Outage Information: SCE | LADWP

The heat was blamed for at least some of the outages reported Sunday night by Southern California Edison. More than 4,400 customers were without power in Los Angeles County and nearly 5,000 in Orange County as of 3:30 a.m., with equipment failure the main cause. The LADWP also noted spot outages around its coverage area.

An outage in La Canada Flintridge left a shopping center, including a Trader Joe's store, without power Monday morning. 

A Flex-Alert is a request for customers to voluntarily conserve electricity, including turning off unneeded lighting, postponing the use of major appliances including washing machines and dryers, and setting air conditioning thermostats to 78 degrees or higher.

The Los Angeles DWP urged residents to prepare for possible power outages by having flashlights and batteries readily available and keeping a battery-operated radio handy. DWP officials also recommended that people keep a phone charger in a car to ensure they can contact friends or relatives during an outage, keep a supply of non-perishable food and have a cooler available to use for food that needs to be refrigerated.

The heat wave included a record-setting Sunday, when a reading of 109 degrees was reported at 2:36 p.m. Sunday at Bob Hope Airport in Burbank. Palmdale and Lancaster topped out at 105 and 106 degrees respectively, the temperature at Long Beach Airport hit 100 degrees, downtown LA topped out at 96 degrees and LAX hit 85 degrees. It hit 107 degrees in Beverly Hills.

Many beaches were not much cooler: it was 94 at Seal Beach and 88 at Zuma Beach.

Red flag warnings continue until 8 p.m. Tuesday in the San Gabriel Mountains and through 10 a.m. Tuesday for the Santa Barbara mountains and south coast, where the Sherpa Fire continued to burn. Gusty sundowner winds were expected to continue today which should continue to fuel the Sherpa fire now burning near Goleta in Santa Barbara County, the NWS reported.

Minor relief was expected in coastal and valley areas beginning Tuesday, but the San Gabriel Mountains and the Santa Clarita Valley were to remain dangerously hot.
