California wildfire fight aided by better weather

California wildfire fight aided by better weather

By Steve Gorman

LOS ANGELES (Reuters) – Thousands of weary firefighters, battling a deadly 2-week-old California wildfire that ranks as the third largest in state history, welcomed a second straight day of favorable weather on Monday that allowed a more aggressive attack on the flames.

The so-called Thomas fire has scorched 271,000 acres (110,000 hectares) of drought-parched chaparral and brush in the coastal mountains, foothills and canyons of Ventura and Santa Barbara counties northwest of Los Angeles.

The burned zone encompasses an area about a third of the size of the state of Rhode Island.

More than 1,000 homes and other buildings have gone up in flames and some 18,000 other structures remained threatened from a late-season firestorm that kept firefighters on the defensive for the better part of two weeks.

One firefighter lost his life, succumbing to smoke inhalation and burns last Thursday near the town of Fillmore in Ventura County.

A mix of lighter winds, rising humidity and cooler air temperatures prevailed for a second day on Monday, affording crews the greatest weather break they had seen yet, said Lynne Tolmachoff, a spokeswoman for the California Department of Forestry and Fire Protection (CalFire).

“Everybody is breathing a sigh of relief that this will give those firefighters a chance to get in there and do some good work, and not just be constantly chasing things,” she told Reuters by telephone.

A firefighting force of 8,500 personnel had carved containment lines around 50 percent of the blaze’s perimeter as of Monday night, up from 45 percent earlier.

But coastal communities within the towns of Santa Barbara, Montecito and Summerland were still at risk as crews hurried to extend and shore up buffer zones before a return of higher winds forecast for Wednesday, Tolmachoff said. Full containment is not expected before the second week of January.

The blaze erupted on Dec. 4 and was stoked by hot, dry Santa Ana winds blowing with rare hurricane force from the high desert to the east, spreading the flames across miles of rugged coastal terrain faster than firefighters could keep up.

The latest tally of burned landscape puts the Thomas blaze among the three largest wildfires documented in California, approaching the record size of the 2003 Cedar fire in San Diego County that consumed 273,246 acres (110,600 hectares) and killed 15 people.

The Thomas fire has displaced more than 100,000 people, although authorities in Santa Barbara County lifted evacuation orders for additional areas no longer considered to be in harm’s way, and more communities were to be reopened on Tuesday.

CalFire has put the estimated cost of fighting the blaze at nearly $131 million. The cause remained under investigation.

The Thomas came two months after a spate of wind-driven blazes in Northern California’s wine country incinerated several thousand homes and killed more than 40 people, ranking as the deadliest rash of wildfires, and one of the most destructive, in state history.

LOS ANGELES (Reuters) – A California wildfire was close on Saturday to becoming the state’s third largest blaze on record, with more devastation possible from a resurgence of the harsh winds that have fueled the deadly fire’s growth.

The so-called Thomas Fire has destroyed more than 1,000 structures, including about 750 homes, in coastal communities in Southern California since erupting on Dec. 4, the California Department of Forestry and Fire Protection said in a statement.

It has cost $97 million to fight the 256,000-acre (103,600-hectare) blaze, with thousands of firefighters contending with it around the clock and helicopters and airplanes being used to drop retardant on the flames.

The vast landscape charred by the blaze, which is centered less than 100 miles (161 km) northwest of downtown Los Angeles, is approaching the 257,314 acres (104,131 hectares) destroyed by California’s Rim Fire in 2013. The Rim Fire is the third-largest blaze on record in the state.

The Thomas Fire is only 35 percent contained and it threatens 18,000 structures, officials said, including some in the wealthy enclave of Montecito just outside the city of Santa Barbara. The blaze is chewing up tall grass and brush as it expands along the scenic Pacific Coast.

The hot Santa Ana winds that have helped the fire grow, at times sending embers far ahead of its main flank, were forecast to remain strong through Saturday evening in the Santa Barbara County mountains, the National Weather Service warned. Gusts of up to 40 miles per hour (64 km/h) were expected.

From Saturday night through Sunday evening, the winds could lash neighboring Ventura County, the Weather Service said. That is where the Thomas Fire first began due to unknown causes, and where it was still burning.

Cal Fire engineer Cory Iverson, 32, died on Thursday while battling the flames near the Ventura County community of Fillmore. Fire officials said Iverson, the blaze’s first fatality, left behind a pregnant wife and 2-year-old daughter.

The Thomas Fire was one of several major blazes that broke out in Southern California this month, although the others have been contained.

The blazes forced many schools to close for days, shut roads and drove hundreds of thousands from their homes. The fires were also responsible for poor air quality throughout Southern California.

Firefighter killed battling massive California blaze

Firefighter killed battling massive California blaze

By Dan Whitcomb

LOS ANGELES (Reuters) – A firefighter was killed on Thursday while battling a mammoth California wildfire as crews sought to protect coastal cities and towns in the path of flames that have destroyed more than 700 homes.

The flag-draped remains of firefighter Cory Iverson, 32, were driven out of the fire zone in Ventura County, northwest of Los Angeles, in a hearse as his comrades saluted from roadsides and overpasses.

“Anne and I are saddened by Engineer Cory Iverson’s tragic death. His bravery and years of committed service to the people of California will never be forgotten,” California Governor Jerry Brown said in a statement.

Fire officials released little information about the circumstances surrounding Iverson’s death, which came while he was fighting the so-called Thomas Fire, now the fourth-largest wildfire on record in California since 1932.

The Los Angeles Daily News reported that Iverson, a California Department of Forestry and Fire Protection engineer, perished in an accident near the community of Fillmore, where a mayday alert was sounded.

The Thomas Fire, which erupted on Dec. 4 near a small private college in Ojai, has since blackened more than 249,000 acres.

The conflagration advanced again overnight to surpass the Zaca Fire, which struck Santa Barbara County in 2007, charring 240,000 acres (97,120 hectares).

The Thomas Fire, which was 35 percent contained as of Thursday evening, has burned 729 single-family homes to the ground and damaged another 175. The blaze has displaced more than 94,000 people.

The wildfire remained a threat to some 18,000 homes and other structures in the communities of Santa Barbara, Carpinteria, Summerland and Montecito along California’s scenic coastline, especially if hot, dry Santa Ana winds return.

Red-flag warnings, issued for extreme fire weather conditions in the area, were extended through Friday morning.

“Right now, there really is a fear in the community. We’re very used to fire, but the magnitude of this one is something that we haven’t seen,” Monique Limon, a state assembly member whose districts includes parts of Ventura and Santa Barbara counties, told Reuters

Many public schools in the Santa Barbara area canceled classes this week and will not reopen until the annual winter break ends in January.

Some of the other fires burning over the past week in San Diego and Los Angeles counties have largely been brought under control.

Investigators determined that the Skirball Fire, which destroyed six homes in Los Angeles’ wealthy Bel-Air neighborhood and scorched a building at a winery owned by media mogul Rupert Murdoch, was started by a cooking fire at a homeless encampment, the Los Angeles Fire Department said earlier this week.

The Lilac Fire, which burned more than 4,000 acres (1,620 hectares) in northern San Diego County and destroyed 157 structures, was 97 percent contained as of Thursday, Cal Fire said.

Vicious winds to test crews battling California wildfire

Vicious winds to test crews battling California wildfire

By Dan Whitcomb

LOS ANGELES (Reuters) – Firefighters in California will be tested by vicious winds on Friday morning as they battle a huge wildfire that has claimed the life of one of their colleagues and torched more than 700 homes.

Cory Iverson, 32, a California Department of Forestry and Fire Protection engineer, was killed on Thursday while tackling the so-called Thomas Fire in Ventura and Santa Barbara counties.

“Cory Iverson … made the ultimate sacrifice to save the lives of others,” said Ventura County Sheriff Geoff Dean during a community meeting on Thursday night.

Fire officials released little information about the circumstances surrounding Iverson’s death. The Los Angeles Daily News reported that he perished in an accident near the community of Fillmore, where a mayday alert was sounded.

Santa Ana winds and humidity in the single digits has helped stoke the blaze that has swept through dry vegetation since it erupted on Dec. 4 near a small private college in Ojai. It has since blackened more than 249,000 acres (about 390 square miles, or 1,000 sq km) and is now the fourth-largest wildfire on record in California since 1932.

On Friday morning powerful winds are forecast which will subside during the day, the National Weather Service said.

“Winds will weaken Friday, turn westerly early Saturday, then become offshore and gusty again late Saturday night through Sunday evening,” the service said in an advisory.

The wildfire remained a threat to some 18,000 homes and other structures in the communities of Santa Barbara, Carpinteria, Summerland and Montecito along California’s coastline, especially if hot, dry Santa Ana winds return.

The Thomas Fire, which was 35 percent contained as of Thursday evening, has burned 729 homes to the ground and damaged another 175. The blaze has displaced more than 94,000 people.

The fire and others to the south in San Diego and Los Angeles counties have disrupted life for millions of people over the last 11 days.

They have caused schools to close for days, shut roads and driven hundreds of thousands from their homes and into shelters. The fires are also responsible for poor air quality throughout Southern California, forcing some commuters to wear protective face masks, local media reported.

Fierce winds to intensify as firefighters battle California wildfire

Fierce winds to intensify as firefighters battle California wildfire

By Dan Whitcomb

LOS ANGELES (Reuters) – California firefighting crews may face on Thursday another round of fierce gusts that have fed a volatile wildfire, one of the largest in the state’s history, as they protect homes from flames and build control lines.

The so-called Thomas Fire, already the state’s fifth-largest blaze of its kind on record, threatened the communities of Santa Barbara, Carpinteria, Summerland and Montecito early on Thursday after destroying more than 700 homes since it began on Dec. 4, fire officials said.

“Firefighters will remain engaged in structure defense operations and scout for opportunities to establish direct perimeter control,” the California Department of Forestry and Fire Protection said in a statement, noting that the fire threatened 18,000 structures.

Gusty Santa Ana winds were forecast to whip up to 50 mph (80 kph) early in the morning and peak during the day before decreasing by evening, while warm temperatures and single-digit relative humidity persist, the National Weather Service said in an advisory.

The weather conditions will “contribute to extreme fire behavior. Any fires that develop will likely spread rapidly,” the weather service said in an advisory.

The Thomas Fire has traveled 27 miles (43 km), blackening more than 371 square miles (953 square km) in Ventura and Santa Barbara counties, an area larger than New York City.

The conflagration has destroyed 709 single-family homes, damaged 164 others and displaced more than 94,000 people. It was 30 percent contained as of Wednesday evening.

Many public schools in the Santa Barbara area canceled classes this week and will not reopen until the annual winter break is completed in January.

Some of the other fires burning over the past week in San Diego and Los Angeles counties have been largely brought under control.

Investigators determined that the Skirball Fire, which destroyed six homes in Los Angeles’ wealthy Bel-Air neighborhood and scorched a building at a winery owned by billionaire media mogul Rupert Murdoch, was started by a cooking fire at a homeless encampment, authorities said on Tuesday.

The Lilac Fire, which burned more than 4,000 acres (1,620 hectares) in northern San Diego County and destroyed 157 structures, was 96 percent contained by Wednesday, Cal Fire said.

After fires, Southern California faces risk of mudslides

After fires, Southern California faces risk of mudslides

By Ben Gruber and Alex Dobuzinskis

CARPINTERIA, Calif./LOS ANGELES (Reuters) – Firefighters in Southern California are slowly gaining control of one of the largest wildfires in state history, but residents may not enjoy much relief as experts said the flames are laying the groundwork for the next disaster – mudslides.

The intense fire is burning away vegetation that holds the soil in place and baking a waxy layer into the earth that prevents the water from sinking more than a few inches into the ground, experts said.

With one heavy rain, the soil above this waterproof layer can become saturated, start to slide in hilly areas and transform into something catastrophic.

“Pretty much anywhere there’s a fire on a steep slope, there’s cause for concern,” Jason Kean, research hydrologist for the U.S. Geological Survey, said in a telephone interview.

And the Thomas Fire, which has burned 234,000 acres and destroyed nearly 700 homes in Ventura and Santa Barbara counties, is definitely in landslide country.

“If we get hard rain, there are going to be terrible landslides in the burn areas,” Carla D’Antonio, chairman of University of California, Santa Barbara’s environmental studies program, said in an email.

“It doesn’t take a lot of rain to get the soil and rock moving, so to have burned soil on top of this and no significant plant cover creates huge potential for landslides,” she added.

Among the cities at risk is Santa Barbara, with 92,000 people, as well as the smaller communities of Carpinteria, Ojai and Summerland.

“It’s terrifying,” Jamey Geston, 19, of Carpinteria, said of possible mudslides. “I am just taking it one natural disaster at a time at this point and try to get through it.”

Once the fire is out, more work will begin as officials will likely need to rush to build retention basins and other structures to prevent debris flows before the rainy season begins, said Professor Nicholas Pinter of University of California, Davis’ Department of Earth and Planetary Sciences.

“This is exactly the thing we worry about in the winter following an event like the Thomas Fire,” he said by telephone.

Another large concern is the potential damage to water quality, Santa Barbara Mayor Helene Schneider said in a telephone interview.

Heavy rainfall could bring lots of silt to waterways like Lake Cachuma, where barriers are already being erected, as well as unwanted matter, she said. In 2007, after the massive Zaca Fire, Santa Barbara spent more than $1 million on extra cleaning and filtration systems.

The Federal Emergency Management Agency and the state could defray some costs with grants, but the best outcome would be “a nice, calm, intermittent rain,” Schneider said.

“We don’t see any rain in the immediate forecast, which is a curse and a blessing,” she said. “We could use the water to fight the fire, but we don’t want some kind of big downpour that would cause significant mudslides so soon after the area’s been burnt to nothing.”

Firefighters look to gain on California wildfire as winds persist

Firefighters look to gain on California wildfire as winds persist

By Ben Gruber

VENTURA, Calif. (Reuters) – Firefighters on Tuesday hoped to take further control of a massive California wildfire, the fifth largest in the state’s history, as relentless wind gusts and bone-dry weather were expected to persist.

The blaze, known as the Thomas Fire, which has burned 231,700 acres in Ventura and Santa Barbara counties about 100 miles northwest of downtown Los Angeles, grew but at a slower pace, the Department of Forestry and Fire Protection (Cal Fire) said.

Strong wind gusts of up to 40 miles per hour (65 km per hour) and extremely low humidity expected through Thursday will pose a challenge to firefighters, the National Weather Service said. (Graphics on ‘Southern California wildfires’ – http://tmsnrt.rs/2jCVLeu)

“That combination of winds and very low relative humidity leads to critical fire conditions and can allow for a potential of significant fire growth and fire behavior,” National Weather Service incident meteorologist Rich Thompson said late Monday at a community meeting about the fire.

About 7,000 firefighters were battling the Thomas Fire, which has destroyed nearly 800 structures including more than 680 homes, Cal Fire said. By Monday night the blaze was at least 20 percent contained.

Dry vegetation that has not burned in 50 years has acted as fuel for the fire in the mountains southeast of Santa Barbara and northwest of Ventura counties, spokesman Ian McDonald said.

“Because the slopes are so steep and the terrain is so rocky, it is actually quite dangerous,” he said. “We are not going to put firefighters in harm’s way halfway up a steep rocky slope. We are going to wait for the fire to come to us and extinguish it where it is safe.”

Public schools in Santa Barbara and school districts nearby have canceled classes this week and will not reopen until the annual winter break is completed in January, said Santa Barbara Mayor Helene Schneider.

Some of the other fires burning over the past week in San Diego and Los Angeles counties have been largely brought under control by the thousands of firefighters on the ground.

The Creek and Rye fires in Los Angeles County were both at least 90 percent contained, officials said, while the Skirball Fire in the exclusive Bel Air neighborhood of Los Angeles was 85 percent contained.

North of San Diego, the 4,100-acre (1,660 hectare) Lilac Fire was 90 percent contained on Monday after destroying 151 structures.

Weary firefighters brace for second week battling California wildfire

SANTA BARBARA, Calif. (Reuters) – Crews battling a massive wind-driven California wildfire that has torched nearly 800 buildings and charred 230,000 acres are bracing on Monday to protect communities menaced by flames along the state’s scenic coastline.

The Thomas Fire ignited last week and is burning in Ventura and Santa Barbara counties, about 100 miles northwest of Los Angeles.

“Fire will continue to threaten the communities of Carpenteria, Summerland, Montecito and surrounding areas,” the California Department of Forestry and Fire Protection (Cal Fire)said in a Sunday night update.

Santa Ana winds and the rugged mountainous terrain have hindered firefighters as they battle the blaze, which has destroyed 790 houses, outbuildings and other structures and left 90,000 homes and businesses without power.

“A lot of these guys (firefighters) have fought a lot of fires in the past few months and are fatigued,” said Fire Captain Steve Concialdi, spokesman for the Thomas Fire.

Concialdi said firefighters from 11 Western states are aiding firefighting efforts.

The fire is 10 percent contained, down from 15 percent on Saturday after it blew up on Sunday, growing by 56,000 acres in one day and making a run of 7 miles, Concialdi said.

Nearly 5,800 firefighting personnel are working on the blaze, Cal Fire said. The cost of fighting as of Sunday was nearly $34 million, the agency added. It is already the fifth-largest wildfire on record in California.

At the University of California, Santa Barbara, final exams set for this week have been postponed, Chancellor Henry Yang said in a letter to the campus community. Air quality and transportation issues, along with power outages that have affected the school’s information technology department, forced the delay of exams until January.

Some of the other fires burning over the past week in San Diego and Los Angeles counties have been largely controlled by the thousands of firefighters on the ground this week.

Both the Creek and Rye fires in Los Angeles County were 90 percent contained by Sunday morning, officials said, while the Skirball Fire in the posh Bel Air neighborhood of Los Angeles was 75 percent contained.

North of San Diego, the 4,100-acre (1,660 hectare) Lilac Fire was 75 percent contained by Sunday and most evacuation orders had been lifted.

Firefighters race to contain California wildfires as winds set to strengthen

Firefighters race to contain California wildfires as winds set to strengthen

VENTURA, Calif. (Reuters) – Firefighters in Southern California were under pressure on Saturday to contain six raging wildfires, which have destroyed hundreds of buildings and forced tens of thousands of people to flee, before fierce winds are expected to strengthen again.

Forecasters predict wind gusts to increase in intensity by Saturday night, challenging the 8,700 firefighters who have been battling the fast-moving blazes for five days from the San Diego area up the Pacific Coast to Santa Barbara County. The fires killed at least one person, destroyed 500 structures, hurt six people and injured four firefighters.

The strengthening winds “potentially put the fires that are currently burning at risk of spreading,” said Lynne Tolmachoff, spokeswoman for California Department of Forestry and Fire Protection. “Firefighters have been taking advantage of the past 24 hours to try to get containment lines and strengthen them so that does not happen.”

At the peak, about 212,000 people were forced to flee their homes. Evacuation orders were lifted in some areas, welcome news for many in shelters waiting to see if their homes survived.

California governor Jerry Brown on Saturday will meet with residents affected by the fires and tour the wildfire damage in Ventura County northwest of Los Angeles, where the largest of the blazes, the Thomas Fire has charred 143,000 acres (57,870 hectares) and destroyed 476 structures.

“We’re keeping our fellow neighbors and Californians in our hearts and minds. We’re going to recover,” he said on Twitter on Friday.

A 70-year-old woman died in a car crash on Wednesday after smoke inhalation and burns along an evacuation route in Santa Paula, the Ventura County Star newspaper reported, citing medical examiner Christopher Young.

More than 3,800 firefighters from as far away as Portland, Oregon, and Nevada, battled against the Thomas Fire which was 10 percent contained on Friday, up from 5 percent on Thursday.

SMOKE VISIBLE FROM SPACE

A huge plume of smoke flared from the fire in the Ventura County mountains on Friday and was visible on satellite images, the National Weather Service said. Astronauts have captured images showing the wildfires’ smoke visible from space, and the National Weather Service said visibility was being affected in the San Francisco area.

North of San Diego, the Lilac Fire swelled from 10 acres to 4,100 acres (1,659 hectares) in a few hours on Thursday, prompting Brown to declare a state of emergency for San Diego County. The fire destroyed 105 structures.

Fallbrook, known for its avocado orchards, burned, and homes were destroyed in its Rancho Monserate Country Club retirement community. Blazes approached the Camp Pendleton marine base.

A 500-stall stable for thoroughbred race horses at San Luis Rey Downs training site burned late on Thursday, the Los Angeles Times reported.

An estimated 25 to 30 horses died, in addition to 29 horses killed in Los Angeles earlier in the week. A trainer suffered second- and third-degree burns over half her body trying to rescue horses, the newspaper said. She was airlifted to a San Diego hospital and placed in a medically induced coma.

Del Mar Thoroughbred Club, a racetrack in a beachside community north of San Diego, said it was providing refuge for more than 900 animals, mostly horses as well as some goats and pigs. A horse hospital was being opened on Friday.

Wildfires in the Los Angeles area forced producers of commercials, television shows and even student films to pause or seek alternate shooting locations. Applications for filming in the Angeles National Forest were also halted this week.

Property worth billions of dollars is at risk. Some 86,000 homes were at risk in Ventura and Los Angeles counties, according to CoreLogic Inc <CLGX.O> a California-based risk analysis firm, with reconstruction possibly totaling $27.7 billion.

California is still recovering from wildfires in the northern part of the state that resulted in insured losses of more than $9 billion in October. Those fires, which were concentrated in California’s wine country, killed 43 people.

Firefighters battle intense wildfires in Southern California

Firefighters battle intense wildfires in Southern California

By Ben Gruber and Mike Blake

FARIA BEACH/LILAC, Calif. (Reuters) – Firefighters battled several intense wind-driven wildfires early on Friday across densely populated Southern California that have destroyed at least 500 structures and chased tens of thousands of people from their homes over the past five days.

More than 5,700 firefighters from across California and the region worked to stop the spread of six large wildfires and other smaller blazes that have erupted since Monday, from Los Angeles up the Pacific coast to Santa Barbara County, and stoked by fierce westward Santa Ana winds.

Firefighters and helicopters sprayed and dumped water and fire retardant on the inferno, against a hellish backdrop of flaming mountains and walls of smoke as the blaze hopscotched over highways and railroad tracks and torched rows of houses.

Graphic – Southern California wildfires: http://fingfx.thomsonreuters.com/gfx/rngs/USA-WILDFIRES/0100522F4PF/calfire.jpg

The raging fires have forced the evacuation of about 190,000 people and threatened 23,000 homes as of late on Thursday, CAL FIRE said in a post on Twitter.

The Los Angeles Unified School District, the country’s second largest with more than 640,000 students, closed more than a quarter of its nearly 1,100 schools for a second day on Friday. The University of California Santa Barbara canceled Friday classes as well.

The Thomas Fire northwest of Los Angeles grew to 115,000 acres (46,540 hectares) from 96,000 acres (38,850 hectares) and destroyed 439 structures, officials said. More than 2,600 firefighters from as far away as Portland, Oregon, and Nevada were battling the blaze, which was just 5 percent contained.

North of San Diego, another blaze called the Lilac Fire swelled from 10 acres to 4,100 acres (1,659 hectares) in just a few hours on Thursday, CAL FIRE said, prompting Governor Jerry Brown to declare a state of emergency for San Diego County.

The blaze destroyed 20 structures and prompted evacuations and road closures. Propane tanks under several houses exploded from the heat, sounding like bombs, according to a Reuters photographer at the scene.

Three people sustained burn injuries and another suffered from smoke inhalation in the Lilac Fire. Two firefighters were also injured, CAL FIRE said on Twitter early on Friday.

POLLUTION ‘OFF CHARTS’

The other fires, which broke out on Monday and Tuesday, have reached into the wealthy enclave of Bel-Air on the west side of Los Angeles. Some major highways in the densely populated area were intermittently closed.

In the seaside enclave of Faria Beach, caught between burning mountains and the Pacific Ocean northwest of Ventura, fires spread down the smoking hills. Flames jumped the heavily used U.S. 101 highway and headed toward clusters of beach houses. Firefighters lined up along a railroad track, the last barrier from the flames.

Heavy smoke made breathing hazardous in some areas, and residents were urged to stay indoors. Ventura County authorities said air pollution measures in the Ojai Valley were “off the charts.”

The Los Angeles Police Department tweeted, “LAPD Working to Save Every Californian, Pets Included” along with a photo of a police officer in a respirator rescuing a cat. The Los Angeles County animal shelter said it was hosting 184 pets including llamas, donkeys and horses while reports said 29 horses were burned to death on Tuesday at a ranch in the Sylmar neighborhood of Los Angeles.

The Skirball Fire in Los Angeles has forced hundreds of residents in the wooded hills near the Bel-Air neighborhood to evacuate and charred more than 475 acres (192 hectares).

Skirball threatened media magnate Rupert Murdoch’s Moraga Estate winery. The property was evacuated, with possible damage to some buildings, Murdoch said in a statement, but “we believe the winery and house are still intact.”

Utilities cut power to customers in some mountain communities northeast of San Diego and east of Los Angeles to limit fire danger. The outage could last several days.

The fires are the second outbreak to ravage parts of California this autumn. The celebrated wine country in the northern part of the state was hit by wind-driven wildfires in October that killed at least 43 people, forced some 10,000 to flee their homes and consumed at least 245,000 acres (9,900 hectares) north of the San Francisco Bay area.

The California Department of Insurance said the northern California blazes caused insured losses of more than $9 billion.
