More Than 3,000 Lightning Strikes Wallop SoCal Deserts

Thunderstorms and more than 3,000 lightning strikes roared through Southern California deserts Thursday afternoon from the high badlands in Antelope Valley to the low deserts in Riverside and San Diego Counties.
For a short period of time it looked like one needed a snorkel to drive the streets in Palmdale. Sheets of water created afternoon havoc for drivers, as streets were flooded at multiple intersections.
The sounds of thunder were heard over hundreds of miles of Southern California real estate.
Winds howled as rain pushed through neighborhoods. 30 power poles were knocked down in Palmdale and a trampoline was lifted into the air and slammed into the side of a car.
The National Weather Service proclaimed “hail up to one-half inch in diameter is expected to fall…strong wind gusts to 50 mph can be expected.” A spokesman for the service said 2.75 inches of rain fell in Palmdale during a two-hour period.
At 10 p.m. 900 Antelope Valley customers were without power and the energy company that serves the area said the outages will continue “for quite some time” due to the severity of storm damage.
Before it turned dark there was fierce lightning storm that started small brush fires in the eastern portion of the Antelope Valley. No structures burned.
The Inland Empire fell victim to the same storm as the Antelope Valley and was slapped around by a wicked series of afternoon lightning strikes that started several fires.
While there was virtually no rain wild winds and crazed lightning danced over huge swaths of Riverside County making life miserable for folks as temperatures hit triple digits.
At least four major fires started in the Inland Empire Thursday afternoon and were deemed big enough to give names.
The most dramatic fire was dubbed the “Don Juan Incident” in the city of Lake Elsinore. Lightning hit the ground and started a small grass fire, which quickly spread to a travel trailer. Lucky for the handicapped woman inside deputies listened to a young girl and pulled her out just before her home burst into flames destroying the RV.
The “Cactus Fire” in Sage, south of Hemet, burned 375 acres and was only 10 percent contained at 10 p.m. Then there was the 70-acre “Saddle Fire”, also south of Hemet, that was contained at time of this writing. No Structures were burned in either fire.
The fourth fire of note was coined the “Skinner Incident” and was located north of Temecula just south of Winchester. It ate up 450 acres of scrub brush and was only partially contained at 10 p.m.
And not to be outdone there was a pretty good rainstorm in the San Bernardino Mountains. Images showed sheets of rain falling on the main drag in Big Bear.
Late Thursday night the two National Weather Service offices serving Southern California reported there were more than 3,000 lightning strikes this afternoon.
Feelin' hot, hot, hot! . . . . .
Feelin’ hot, hot, hot! Another scorcher is forecast; thunderstorms, lightning, hail, brush fires are possible

Another broiling day is forecast for Southern California on Friday, bringing with it chances of more thunderstorms, lightning and brush fires.
The National Weather Service has extended its extreme heat advisory though at least Saturday night. Triple-digit temperatures are forecast for valley and inland areas. The National Weather Service said residents should be prepared for anything in the afternoon — flash flooding in desert and mountain areas, thunderstorms, hail — and lightning that could cause brush fires.
[Updated at 8 a.m.: Scattered showers hit parts of Long Beach, San Pedro and surrounding cities Friday morning amid hot, humid conditions. The weather service said high-temperature records might be set Friday or Saturday.]
On Thursday, thunderstorms sparked brush fires and caused flash flooding and hail even as inland areas sweltered amid triple-digit temperatures and high humidity.
In Los Angeles County, a powerful afternoon thunderstorm struck the Antelope Valley as fire crews responded to dozens of incidents, including small brush fires and a rescue of two people trapped in mud after a heavy downpour, officials said.
In Riverside County, where more than a dozen brush fires erupted, three sheriff’s deputies suffered minor injuries while they were rescuing a woman from a trailer as flames burned near homes in Lake Elsinore, officials said.
Multiple brush fires also broke out in San Diego County.
“We’ve got small fires and larger fires,” Riverside County Fire Department spokeswoman Cheri Patterson said. “We’re trying to catch up. It’s been hectic.”
The largest had scorched at least 700 acres near Temecula and was being battled by more than 100 firefighters. As of Thursday evening, no structures were threatened in that fire. In Sage, a community east of Murrieta Hot Springs, voluntary evacuations were issued for 80 residents and 15 animals in a blaze that had charred at least 75 acres, officials said. That fire was almost contained by Friday morning .
The National Weather Service issued a significant weather advisory in Riverside County because of strong thunderstorms that barreled across the San Jacinto Mountains. Thunderstorm and flash flood advisories were also issued in the Antelope Valley. The agency advised people in inland areas across Southern California to avoid prolonged exposure to the sun and to drink water to avoid heatstroke and heat exhaustion.
In Los Angeles County, temperatures reached 106 in Chatsworth, 110 in Acton and 107 in Palmdale, according to the weather service. Ojai in Ventura County also reached 107 degrees.
Hemet in Riverside County hit 111 degrees and Lake Elsinore reached 110, the weather service said. The heat and high humidity were expected to last through the weekend, the weather service said.
In rural northeastern San Diego County, mid-afternoon lightning strikes caused four brush fires. The largest occurred in the Scissors Crossing area east of Julian and spread more than 100 acres. The fires were not threatening any structures, a spokesman for the California Department of Forestry and Fire Protection said.
Within the San Diego city limits, a fire in a brushy canyon in the University Heights neighborhood forced the evacuation of about 20 homes and a nearby hotel. The fire sent smoke over Interstate 8 and portions of Mission Valley, but firefighters and water-dropping helicopters stopped the advance of the fire before it reached the rim.
