Firefighters continue to battle wildfires in San Diego County, California

LOS ANGELES (CNN) -- Erica Bene was running errands at Camp Pendleton in California with her two children when she spotted a huge plume of smoke behind a school.

A wildfire was coming her way despite progress made by an army of firefighters in San Diego County in quelling a spate of blazes this week.

They're winning the battle. At least four wildfires were completely contained early Saturday. Two more were nearly contained, and four others were steadily shrinking.

But early Saturday, thousands of acres were still in flames that were driving walls of smoke skyward. The fire has scorched more than 31 square miles so far.

The blazes in the state so far this year are "unprecedented," Cal Fire Director Ken Pimlott has said.

Flames have swallowed up dozens of homes and businesses. And the wildfire season has only just begun.

Bene, the wife of a U.S. Marine deployed to Afghanistan, headed home to pack up some important items and evacuate.

"I said 'let's go get the pets, and let's get out of here," she said.

On the drive back home, orange flames raged. Shortly thereafter, the Marine Corps put out an evacuation order.

The order spooked her 5-year-old son and 7-year-old daughter, but she explained that it didn't mean their house would burn down. The order just gave firefighters room to combat the blaze without having to worry about danger to residents.

Her children are used to feeling uneasy because of their dad's dangerous deployment, Bene said.

She took her children and the pets to a friend's home in nearby Temecula, where they plan to stay the night.

By late Friday, the evacuation order had been lifted. If it remains lifted, she plans to go home Saturday morning.

Arson arrests

Investigators have filed an arson charge against a man in one small fire in the county.

At a news conference, the prosecutor identified him as Alberto Serrato, who's accused of adding brush onto an existing fire, District Attorney Bonnie Dumanis said.

Serrato could face up to seven years in prison if convicted, Dumanis said Friday.

Neither Serrato nor his attorney were immediately available for comment.

Meanwhile, the prosecutor is weighing whether to press charges against a 19-year-old man and 17-year-old juvenile, both of Escondido, who were arrested Thursday in connection with a small fire that was extinguished, Dumanis said.

Thousands on the move

Thousands of firefighters used air tankers, specially equipped DC-10s and military helicopters to douse the flames this week.

Bene was just one of tens of thousands of residents to evacuate.

In all, 176,000 notices of evacuation were sent throughout San Diego County via cell phone calls, e-mails, text messages and calls to homes and businesses, county Supervisor Dianne Jacob said.

When Elisha Exon saw towers of smoke looming over her San Marcos, California, home, she knew it was time to go. The only problem: All the nearby places she'd normally take her family in an emergency were threatened by fire, too.

"You kind of feel like your only safety would be to hop town, completely," she said.

Ash and smoke filled the air in many places, making breathing difficult.

So far, injuries have been few: Authorities found a charred body in Carlsbad, but it was unknown whether the person died because of the fire. A Camp Pendleton firefighter suffered heat exhaustion.

Homes in the crosshairs

Thousands of homes across the county are still in jeopardy.

"I've been doing this for 20 years," San Diego County Supervisor Bill Horn said. "This is the worst I've seen."

Images from the fires were jarring.

The night sky glowed orange from towering flames that consumed homes. Whirling columns of flame -- dubbed "firenadoes" or "fire whirls" -- spun across the landscape, in one case nearly devouring a hilltop home.

Firenadoes can spit out winds as powerful as an EF-2 tornado.

In video shot by Jeb Durgan and Byron Bowman, a helicopter wheeled over homes, dumping fire retardant just yards from a burning canyon choked with flames. Smoke obscured the road the two were driving on.

Evolution of a disaster

The wave of wildfires started Tuesday with the Bernardo Fire in San Diego County. The next day, new blazes popped up -- each one separate from the others, each posing its own dangers.
