Southern California woke to the acrid smell of smoke and ash Thursday morning as additional wildfires broke out along the edges of the Los Angeles Basin and Orange County coastline.
Combined with other blazes that ignited earlier in the week, at least half a dozen wildfires have filled the air with a pungent odor long associated with fire season, when hot temperatures and strong winds turn sparks into brush fires.
The scene was particularly noticeable Thursday because an inversion layer had settled over the region, trapping the fumes.
California’s landscape is vulnerable to fast fires as the wettest winter in more than a decade helped lay down a thick carpet of grass that withers rapidly in summer heat.
The fires stretch from San Luis Obispo County in the north to
Flames that tore through the northwestern part of Camp Pendleton slowly moved into San Clemente overnight and have burned an estimated 760 acres, the Orange County Fire Authority said Thursday.

The fire was reported about 6:15 p.m. Wednesday when it was already 15 acres and growing near the San Mateo Campground and Cristianitos Road, according to Camp Pendleton officials.
Officials said the blaze, dubbed the Cristianitos fire, was heading away from the Marine base and was just east of Richard T. Steed Memorial Park, a recreation area next to a cluster of businesses and a golf course.
Crews lit backfires on three sides of the fire overnight to limit its spread, said fire Capt. Larry Kurtz. Backfires are used to burn fuel in the fire’s path.
The western face of the fire closest to homes is protected by extra firefighters, Kurtz said.
“The fire has slowed to a crawl. There is no wind, which is a huge benefit to us,” Kurtz said.
The fire is moving based on topography, making its behavior somewhat predictable. The biggest challenge has been how fast it moves.
“During the winter we had heavy rains create a very large grass crop throughout California.… It’s a less intense fire but one that moves very quickly,” Kurtz said.
The fire was 70% contained as of Thursday night.
In Calabasas, firefighters were trying to control a fire that quickly swelled to 40 to 50 acres.
Located near Malibu Canyon and Mulholland Drive, the so-called Stokes fire was reported about 3 p.m. Thursday and grew in the remote area with moderate winds.
By 4:30 p.m., more than 220 firefighters had stopped the forward progress of the flames. Late Thursday, the fire was 80% contained, according to the
One firefighter suffered a heat-related injury, according to the Fire Department.
The Topanga fire was reported near Topanga Canyon Boulevard and Pacific Coast Highway.
The Los Angeles County Fire Department said that about 25 acres had burned and that firefighters were ready to protect homes in the Malibu area if the fire grew.
As firefighters battled the blaze, motorists faced gridlocked traffic along Pacific Coast Highway and road closures.
A stretch of Pacific Coast Highway was closed during the afternoon and evening, but all lanes were reopened by 9 p.m., according to the CHP.
The Burbank fire broke out just before 3 p.m. Wednesday near Hamline Place, where it raced up a grassy slope and moved dangerously close to homes in the Verdugo Mountains and briefly triggered mandatory evacuations.
Los Angeles County
Authorities were concerned because houses “butt right up to the hillside,” Burbank Police Sgt. Derek Green told KNBC-TV Channel 4.
“It was a fast-moving fire,” Green said. “This is a very dry area.”
Television news footage showed thick black smoke and tennis courts burning.
About 15 fire engines responded to the three-alarm blaze, Burbank Fire Battalion Chief Ron Barone told KTLA-TV Channel 5. Five engines were dedicated just to protecting homes, he said.
The fire spread across 10 acres but did not grow overnight, Barone said. The fire was between 85% and 90% contained Thursday morning, he said.
“Our plan calls for nobody to be on the fire line by 7 tonight,” Barone said. “There’s no push left in it.”
No structures were damaged in the fire, Barone said.
Immediately after the fire began, the Burbank Police Department ordered evacuations of all homes on Viewcrest Drive and Howard Court. Irving Drive was closed east of Kenneth Road, and Joaquin Drive was closed at Haven Way.
But by 8:30 p.m., all evacuations were lifted.
About 150 firefighters were assigned to the blaze, which helped to quickly halt the fire’s growth.
“Our incident commander saw the threat and pulled the trigger,” Barone said.
Given light winds and cooling temperatures, crews in Riverside County doubled the containment of the Manzanita fire to 90% by Thursday night. The fire has burned 6,309 acres, according to the California Department of Forestry and Fire Protection.
The blaze was sparked Monday by a car crash along Highway 79 in the San Jacinto Mountains and was fueled by high temperatures, low humidity and wind gusts of up to 35 mph.
Residents in areas like Poppet Flats and Silent Valley spent more than a day under an evacuation warning in which they needed to be prepared to flee if the winds changed and the flames ran down the hills toward their homes. Those warnings were finally lifted Wednesday.
More than 700 firefighters are continuing to work to fully contain the fire and knock down any smoldering hot spots, Cal Fire said.
On Tuesday night, another blaze erupted east of San Bernardino and fewer than 30 miles north of the Manzanita fire.
San Bernardino County
The Mart fire raced up a steep canyon in the San Bernardino Mountains around 3:15 p.m. Its flames came within feet of igniting a suburban hillside neighborhood and forced residents of roughly 200 homes to evacuate.
Firefighters managed to stop its advance with aircraft and ground crews and lifted evacuation orders a few hours later. Highway 330 was reopened Wednesday.
The fire started near a Wal-Mart at Highland Avenue and Highway 330, a popular thoroughfare that leads to Big Bear.
Reconnaissance flights caused authorities to reduce the estimated size of the blaze. The fire is 670 acres and 60% contained, the U.S. Forest Service said Thursday night.
About 125 firefighters were assigned to the blaze as of Thursday, and the cause is under investigation.
In San Luis Obispo County, the Hill fire started Monday and has burned 1,598 acres. On Thursday, it was 88% contained, Cal Fire said.
The blaze was burning along the eastern foothills of a coastal mountain range near Santa Margarita, among secluded homes and tall, dry grass.
San Luis Obispo County
Crews spent Wednesday shoring up defensive lines around the fire, including cutting down swaths of trees to create a fuel break for the flames. All road closures in the area have been lifted.
Four homes were destroyed in the fire. According to TMZ, “Big Bang Theory” actor Johnny Galecki’s ranch was among the properties charred by flames.
In a statement to the website, Galecki said: “My heart goes out to all in the area who are also experiencing loss from this vicious fire, the threat of which we live with constantly, which may seem crazy to some but we do so because living in our beautiful, rural area makes it worthwhile. It's never the structures that create a community — it's the people. And if the people of Santa Margarita have taught me anything it's that, once the smoke has cleared, literally and figuratively, it's a time to reach out and rebuild. We've done it before, and will need to do it together again, and it will make our community even closer and stronger. Endless thanks to Cal Fire and the Sheriff's Office. I know you guys are fighting the good fight to keep us safe. So very relieved no one has been hurt."
The Placerita fire started Sunday afternoon when a motorist crashed into a tree, according to the Los Angeles County Fire Department.
The blaze burned 760 acres and was 95% contained by the end of Wednesday. Authorities anticipate having the blaze completely out by Thursday, officials said.
Los Angeles County
In its first hours over the weekend, the blaze had knocked out power and triggered mandatory evacuations for dozens of residents after it jumped the freeway and sent up a towering plume of gray smoke that was visible for miles.
At Golden Oak Ranch, an 890-acre filming location constructed by Disney and ABC studios, the fire burned a structure that had been used as a prop house, said L.A. County Sheriff's Department spokesman Christopher Craft.
U.S. Forest Service firefighters stopped the blaze from burning other structures in the faux business district and suburban street used for filming movies and television shows.
Cal Fire and the U.S. Forest Service list several other active fires burning in the state from San Diego to Modoc counties, the two largest of which were nearly contained Thursday at about 1,500 acres apiece.
About 2,300 wildfires on state and federal land have burned 26,000 acres so far in 2017, according to government statistics.
