Temperatures set to top 120 degrees as monster heat wave hits Southern California

[Robrites]

The most severe heat wave so far this year is bearing down in Southern California, with temperatures likely to top 120 degrees.
So how hot will it get?
Temperatures in downtown Los Angeles are expected to climb from the mid-80s Saturday to the mid-90s by Sunday, while triple-digit temperatures are on tap for the valleys.
But it’s Monday, the first day of summer, that is expected to be the hottest. The looming heat has prompted the National Weather Service to issue excessive-heat watches for L.A., the valleys and mountains Monday.
“It will be very hot,” said Joe Sirard, a meteorologist with the service. “People should limit their time outside during the day.”
Here are some predicted high temperatures Monday from the National Weather Service:
Palm Springs: 121
Los Angeles: 100
San Bernardino: 110
Santa Ana: 98
Palmdale: 106

Dangerous, heat-related illnesses such as heat stroke are possible, the weather service said, especially among those who plan on spending Monday outdoors or people without access to air conditioning.
Forecasters warned against leaving people or pets in enclosed vehicles — even for a short period of time.
Power outages are possible as well, the weather service said.
Other agencies have also issued warnings against the heat. The Occupational Safety and Health Administration recommended frequent breaks in shaded or air conditioned areas.
The Los Angeles County Public Health Department said it plans to issue a heat alert Sunday through Tuesday, when temperatures are expected to start to decline.

The blistering heat is the result of an upper-level ridge of high pressure that is building slowly over Southern California. Sirard said the system should start to weaken by Tuesday and temperatures should start to drop.

5 %.

 

[Pinball Wizard]

it's a dry heat...

 

[Betterhaff]

120* is hot, whether dry or humid. But high humidity and high heat can be stifling...hot liquid air.

 

[7thson]

It's only gonna be 115 today.

 

[St. Phatty]

high temps + CO2 supplementation + homes surrounded by combustible biomass = big-time wildfire summer.

30 years ago 389 ppm was the recommended level for CO2 supplementation ... now it's 400 ppm everywhere.

No wonder plants are growing when they get the chance.

Two fast-moving fires burn near Azusa and Duarte as triple-digit temps and winds hit

Two fast-moving fires burn near Azusa and Duarte as triple-digit temps and winds hit

Two brush fires erupted Monday in Azusa and Duarte as temperatures soared past 100 degrees across Southern California.

The first blaze, called the Reservoir fire, was reported about 11 a.m. at Highway 39 in the San Gabriel Mountains, said Andrew Mitchell, spokesman for the Angeles National Forest.

U.S. Forest Service crews, along with Los Angeles County firefighters, were responding to the 100-acre blaze. Water-dropping helicopters were aiding in the firefight.

More than an hour later, a second 100-acre fire, dubbed the Fish fire, erupted near Brookridge Road and Opal Canyon Road in Duarte, said Capt. Keith Mora, spokesman for the Los Angeles County Fire Department.

“It’s moving fast,” he said.

Flames were moving rapidly uphill, but were not near homes.

Firefighters were working under “extremely dry conditions, over 100 degree temperatures” and 12 to 15 mph gusts as they battled the Fish fire, Mora said.

A red flag warning has been issued for Southern California through Tuesday morning. Temperatures are expected to hover in the triple digits in Los Angeles and remain in the 90s near the Sherpa fire in Santa Barbara County, authorities said. That blaze is the largest active fire in California, according to state and federal data.

In San Diego County, a wildfire fueled by dry brush and sweltering temperatures has scorched 1,500 acres just north of the U.S.-Mexico border and prompted mandatory evacuations for the entire east county community of Potrero.

About 25 homes south of state Route 94 and east of state Route 188, near where the fire initially sparked about 11:30 a.m. Sunday, were also evacuated. The cause of the fire was not immediately clear.

“Widespread triple digit heat combined with humidities in the teens and single digits will bring an extended period of elevated fire danger across much of Southwest California through at least Tuesday, with extreme fire danger for parts of the area,” the National Weather Service said.

Gusting winds were expected to last through Tuesday evening for Los Angeles and Ventura counties.

Record-setting heat wave leads to blackouts in L.A.

Record-setting heat wave leads to blackouts in L.A.

Thousands of Los Angeles residents lost power Monday as scorching temperatures kept people inside while running fans and air conditioners that strained the power grid, officials said.

As of 9:30 p.m., about 6,200 Department of Water and Power customers lost electrical service, department spokeswoman Christy Holland said.

The vast majority of those experiencing power outages -- about 5,500 customers -- reside in the San Fernando Valley, Holland said. The rest were scattered in pockets across metropolitan L.A.

The DWP has about 1.4 million customers across the city.

Sweltering heat strained the city’s electrical system, and the DWP said in a statement that Monday’s peak demand, 6,080 megawatts, was more than 50% higher than energy demand on a usual June day.

Thousands experienced blackouts at various times Monday. The most outages occurred about 7 p.m., when 11,469 DWP customers lost power, Holland said. The DWP did not have information about the total number of customers who lost power during the day.

Officials expect power to be restored about six hours after the electricity initially shut off.
