CBS News Correspondent Mark Strassmann toured the fire zone with Gov. Charlie Christ. The smoke was so thick, they couldn't even see what was burning.
"It's unconscionable that somebody would do this to another man and woman, and put them in jeopardy in this way," Gov. Crist.
Firefighters in Brevard County were trying for the third day to contain fires that have scorched about 3,800 acres, or 6 square miles, in Palm Bay and neighboring Malabar.
Though the high winds fueling the flames Monday had slowed significantly, officials worried about the flames spreading quickly in the dry conditions.
"We desperately need rain," said Palm Bay Fire Marshal Mike Couture. "We don't have any, and we're not projected to get any anytime soon."
All 18 schools in Palm Bay were closed Tuesday. Smoke and the proximity of the flames have caused the intermittent closure of major highways in the area, including a 34-mile section of Interstate 95 south of the fires that was closed again midmorning Tuesday.
"Flames are coming onto the interstate," Florida Highway Patrol Trooper Kim Miller said.
The worst fires raged uncontrolled in Malabar, while officials said they had "a majority" of the Palm Bay fires contained.
Palm Bay police were working with the state fire marshal's office and Brevard County Fire Rescue to investigate who set an estimated nine fires that spread into a larger, uncontrollable blaze.
"Some are caused by embers that are flying, but the locations of the fires indicated that these were initiated separately, which makes us firmly believe that an individual or individuals was involved in setting those," Police Chief Bill Berger said.
Lee Feldman, city manager of Palm Bay, estimated 162 houses in his community were severely damaged or destroyed, causing an estimated $4.2 million in damage.
Neighborhoods built into dense woods were surrounded by ashes, twisted limbs and charred tree trunks where the fires raged through. Many homes, however, were saved.
Angel Pagan, a 35-year-old salesman, watched Tuesday as firefighters hosed down the smoldering woods surrounding his home. A night earlier, he neighbors used garden hoses and buckets of water to douse the flames. Pagan sent his wife and their young sons, ages 1 year old and 1 month old, to stay with a relative.
"I cannot believe it - my house was surrounded, and my house did not go up," Pagan said. "It's pure luck, and God."
Across the street, a stucco home was charred and crumbling. On it was duct-taped a bright red note from the building inspector: Totaled.
"We saved a lot of them. The fire department got here and their house was already on fire," Pagan said, gesturing across the street.
A few miles away, Barry Self, an off-duty Palm Bay police officer, was shoveling dirt over still-smoldering patches of woods across the street from his home. He and two neighbors also used garden hoses late into the night to ward off the fire as it skipped across their yards. Self lost his backyard fence and was without electricity Tuesday afternoon, but he said he considers himself fortunate.
"It looks like a little war zone," Self said of the area. "And we're lucky compared to a lot of people. I'm very lucky. I drove around this morning and saw a bunch of houses just totaled to the ground. It's unbelievable, it really is."
Gov. Charlie Crist was expected later Tuesday to tour the area where he has declared a state of emergency. Federal officials Tuesday authorized funding to reimburse the state's firefighting costs in Breva
