Crews worked Thursday morning to restore power to more than 11,000 customers in the Los Angeles area as the region’s heat wave entered its sixth day, appearing likely to last longer than had been expected.

Thousands of customers were in the dark in Los Angeles County due to weather-related outages. They included 8,300 customers in South Los Angeles and more than 1,000 in the San Fernando Valley, and Department of Water and Power officials said crews were working to repair overloaded equipment in Arleta.

Southern California Edison also reported outages Thursday morning affecting more than 1,400 of their customers in Los Angeles County, plus more than 1,500 in Riverside County.

“The combination of strong high pressure and weak onshore flow will continue to produce dangerously high temperatures across the region through at least Saturday,” according to a National Weather service statement. Previously, forecasters had said the high heat would afflict the region through Friday.

As has been the case since Saturday, the highest temperatures were expected in the San Fernando, Santa Clarita, San Gabriel and Antelope valleys and at lower elevations in the San Gabriel and Santa Monica mountains. Highs in those areas are expected to range from 100 to 112, NWS forecasters said, and overnight lows will not drop below the mid 70s.

Coastal areas will be warm as well, with highs at the beach expected to range from the 80s to the mid 90s and areas a few miles inland expected to be between 95 and 105, with Friday expected to be the warmest day, according to the NWS.

“Some cooling is expected Saturday, but temperatures will still be well above normal and all the current advisories and warnings will continue through at least Saturday evening,” according to the NWS statement.

A heat advisory will remain in effect until 10 a.m. along the coast, in beach cities, in metropolitan Los Angeles and the Hollywood Hills, then be immediately replaced by a more serious excessive heat warning — the first time this week that such a warning has been issued for the coastal zone.

Forecasters again urged caution in response to conditions, including avoiding strenuous work in high heat and drinking plenty of water.

Also, “never, ever leave people or pets in enclosed vehicles, even for a short period of time,” warned an NWS statement, noting interior vehicle temperatures can rapidly rise to lethal levels.

The NWS forecast partly cloudy skies in L.A. County and highs of 84 in Avalon; 87 at LAX; 94 on Mount Wilson; 96 in Long Beach; 98 in San Gabriel; 100 in downtown L.A. and Pasadena; 105 in Burbank; 107 in Palmdale; 108 in Lancaster; 110 in Saugus; and 112 in Woodland Hills. A slight cooldown will get underway Sunday, but only in some communities.

Partly cloudy skies were also expected in Orange County Thursday, along with highs of 75 in Laguna Beach; 80 in San Clemente; 97 in Irvine; 99 in Anaheim and Mission Viejo; 101 in Fullerton; and 102 in Yorba Linda. A cooling trend will begin Saturday.
