Michael Maury hugs Capt. Jeff Michell of the San Diego Fire Department Saturday in the Rancho Bernardo area of San Diego. Michell was part of the crew that saved Maury's home from the wildfires that have ravaged Southern California the past week, destroying thousands of homes and forcing massive evacuations. Scattered showers this weekend helped firefighters battle the blaze.

Lake Arrowhead, Calif. ? Cooler weather helped firefighters make strong gains on many of the wildfires burning across Southern California on Saturday, but officials remained guarded about what the rest of the weekend might bring.

Tropical moisture flowing from the south replaced the hot, skin-cracking Santa Ana winds that roared in a week earlier and spread fires over more than a half-million acres, destroying more than 2,300 structures, including more than 1,790 homes.

By late Saturday more than a dozen blazes were surrounded and containment of nine other blazes ranged from 40 to 97 percent. Fire officials in San Bernardino County said they expected a fire there to be fully contained today.

Today’s weather forecast, however, predicted another shift.

“We’re due for a change and the weather forecast is going to become warmer and drier,” said Chris Caswell with the Orange County Fire Authority. “We’re still cautiously optimistic.”

Death toll at seven

The number of deaths directly attributed to the fires officially rose to seven. Officials confirmed that the flames killed four suspected illegal immigrants whose charred bodies were found near the U.S.-Mexico border on Thursday, said Jose Alvarez, a public information officer for San Diego County emergency services. Identification of the victims was continuing.

The Mexican government said that 11 Mexicans were being treated at a San Diego hospital for burns suffered in Southern California’s wildfires after crossing the border illegally, and four were in critical condition.

Questions about aircraft

Gov. Arnold Schwarzenegger on Saturday visited a command post near Orange County’s Santiago Canyon fire to announce assistance for people with losses, warn of contracting scams and pledge to find whoever set the nearby blaze that continued to threaten homes after destroying 14.

Addressing controversy over state rules that caused delay in getting military aircraft into use against the fires, Schwarzenegger said it sometimes takes disaster “to really wake everyone up.”

“There are things that we could improve on and I think this is what we are going to do because a disaster like this … in the end is a good vehicle, a motivator for everyone to come together,” he said.

Active fires burned in the Lake Arrowhead resort region of the towering San Bernardino Mountains 100 miles east of Los Angeles and in rugged wilderness above isolated canyon communities of Orange County, southeast of Los Angeles. A big blaze 60 miles northeast of San Diego stopped its advance toward the mountain town of Julian.

Living at Wal-Mart

About 4,400 people remained in 28 shelter sites in Southern California, but others waited out the fires in makeshift encampments. In Highland, at the base of the San Bernardino Mountains, about 20 people were in their sixth day of living in a Wal-Mart parking lot, getting daily visits from sheriff’s officials who reported their 17 homes were still intact.

“What are the chances of that? The hundreds of people staying at the shelters, I still don’t think they have the comfort of knowing that kind of information,” said Robert Newbourgh, 44.

Hundreds of evacuees flooded back into Crestline, Valley of Enchantment and Lake Gregory, small mountain communities tucked in canyons and alongside lakes in the San Bernardino mountains.

Light rain fell on the Rancho Bernardo section of San Diego, where more than 360 homes were lost. National Guard troops patrolled and postal trucks delivered mail to homes that were still standing.

“Everybody is really happy for me and I’m sad for them,” said Helena Hyman, a retired school administrator whose cul-de-sac home survived with five ruined homes on each side. She credited her good fortune to replacing wood shingles with a fiberglass roof and chopping down a eucalyptus tree within the last five years.

‘What do you do today?’

Bruce Heinemann, 48, spoke with an insurance adjuster as friends sifted through his ruined home, looking for his wife’s wedding ring, photos and other mementos.

Meanwhile, his daughter was at a newly rented home making lists of what they lost, and his wife was visiting department stores to get prices for the insurers.

“The kind of mode you’re in is, what do you do today? What do you do tomorrow? Just make a list and get it done,” he said.

The Heinemanns had about 10 minutes to evacuate Monday morning, just enough time to escape with some clothes and three of their four cars.

Heinemann, a self-employed loan officer, said it makes financial sense to rebuild, but they may never return to live on the street where the fire left hopscotch destruction – some of the Spanish-style, tile-roofed homes left standing, while others were turned to ash, leaving burned-out cars, chimneys and remnants of refrigerators and washing machines.

“It sounds terrible, but I’m glad it’s gone. How would you like to sit in your house when one third of your neighbors are gone?” he said.morning, just enough time to escape with some clothes and three of their four cars.
