LOS ANGELES — A wildfire erupted in Los Angeles’ exclusive Bel-Air section Wednesday as yet another part of Southern California found itself under siege from an outbreak of wind-whipped blazes that have consumed multimillion-dollar houses and tract homes alike.

Officials said firefighters and aircraft stopped the growth of that 475-acre blaze in the hilly Bel-Air neighborhood.

But hundreds of homes across the L.A. metropolitan area and beyond were feared destroyed since Monday as firefighters were only slowly managing to make their way into some of the hard-hit areas.

As many as five fires have closed highways, schools and museums, shut down production of TV series and cast a hazardous haze over the region. About 200,000 people were under evacuation orders. No deaths and only a few injuries were reported.

From the beachside city of Ventura, where rows of homes were leveled, to the rugged foothills north of Los Angeles, where stable owners had to evacuate horses in trailers, to Bel-Air, where the rich and famous have sweeping views of L.A. below, fierce dry Santa Ana winds sweeping in from the desert fanned the flames and fears.

“God willing, this will slow down so the firefighters can do their job,” said Maurice Kaboud, who ignored an evacuation order and stood in his backyard with a garden hose.

Air tankers that were grounded most of Tuesday because of high winds went up on Wednesday, dropping flame retardant. Firefighters rushed to attack the fires before the winds picked up again. They were expected to gust as high as 80 mph at night.

Before dawn Wednesday, flames exploded on the steep slopes of Sepulveda Pass, closing a section of heavily traveled Interstate 405 and burning at least four homes in Bel-Air, where houses range from $2 million to $30 million.

Firefighters hosed down a burning Tudor-style house as helicopters dropped water on hillside homes to protect them from the 150-acre blaze.

Bel-Air was the site of a catastrophic fire in 1961 that burned nearly 500 homes. Burt Lancaster and Zsa Zsa Gabor were among the celebrities who lost their houses.

Across the wide freeway from the fire, the Getty Center art complex was closed to protect its collection from smoke damage. Many schools across Los Angeles canceled classes because of poor air quality. UCLA, at the edge of the Bel Air evacuation zone, canceled afternoon classes and a basketball game.

In Ventura County northwest of L.A., the biggest and most destructive wildfire grew to 101 square miles and had nearly reached the Pacific on Tuesday night after starting 30 miles inland a day earlier.

The fire destroyed at least 150 structures, but incident commander Todd Derum said he suspects hundreds have been lost.

Meanwhile, more than $9 billion in insurance claims have been filed following deadly wildfires that ravaged Northern California, the state’s top insurance regulator said Wednesday.
