Diane Moultsby bobbed and weaved her way Sunday past strings of insulation dangling from the rafters that once held up the roof of her south Augusta home.

Friday's storm, packing tornadoes that weather officials now say were the worst to hit the area in more than a decade, obliterated Mrs. Moultsby's roof and damaged numerous other homes in the Cherry Hills subdivision off Barton Chapel Road. Overall, the damage spanned a 35-mile stretch from Grovetown to New Ellenton, S.C.

"God gave me the skyroof I've always wanted," she joked.

Damage was still being assessed Sunday, but a National Weather Service official who toured the region estimated more than 100 homes sustained damage, adding he wouldn't be surprised if the cost for all counties affected reaches $1 million.

"I'm sure it's going to be a lot of money," said Leonard Vaughan, a meteorologist with the National Weather Service in West Columbia.

By 8 p.m. Sunday, there were still about 100 South Carolina Electric and Gas customers without service in Beech Island, but power was expected to be restored by this morning. Meanwhile, emergency officials continued to provide help to residents with storm damage, with the Aiken County Chapter of the American Red Cross serving meals to about eight people at a Jackson Middle School shelter.

Suzanne Jackson, with the Red Cross office, said they also had assisted with meals in neighborhoods and offered tarps for homeowners to use to cover holes in roofs.

Over the weekend at Cherry Hills subdivision, the Bobby Jones Expressway location of Home Depot delivered water and building supplies to homeowners, the Augusta Red Cross provided shelter for displaced families, and Augusta commissioners Calvin Holland and Alvin Mason brought food and water to residents, Mrs. Moultsby said. She and many of her neighbors also had covered their roofs with tarps.

In Aiken County, Ms. Jackson said her office had no cost estimate of damage Sunday, but she knew of six destroyed homes, 25 with major damage and 19 with minor damage. She also knew of 11 injured Beech Island residents who were taken to Aiken Regional Medical Centers.

Derrec Becker, a spokesman for the S.C. Emergency Management Division, said his department was still assessing damages and costs and should have a better idea of the storm's scope today.

The storm that swept through several area counties with tornados caused one death -- James Adkinson, a 63-year-old Beech Island resident who drove into some trees Friday night that had fallen across Chime Bell Church Road. Funeral services for Mr. Adkinson will be conducted privately, though the family will receive friends tonight at Shellhouse-Rivers Funeral Home, according to the funeral home's Web site.

Mr. Vaughan said on Sunday his office had determined that a single tornado had tracked from Grovetown to south Augusta to New Ellenton, increasing in speed along its path. Mr. Vaughan said it's rare for this area to have a tornado that travels such a long distance.

He said a separate powerful tornado also hit Burke County.

He said the tornado that spanned Columbia, Richmond and Aiken counties began in Grovetown as an EF1 classification -- wind speeds more than 100 mph -- and grew to an EF2 in south Augusta and further intensified to an EF3 -- with winds more than 150 mph -- in New Ellenton.

"It's been a while since we've had storms of that magnitude," Mr. Vaughan said, noting that the last time was in 1998 when an EF3 tornado hit Edgefield County, causing one death, nine injuries, damage to more than 60 homes and about $1 million in damages.

In Friday's case, he said he knew of 25 homes that were destroyed and "there had to have been more than 100 homes that sustained some kind of damage."

A Burke County man who was thrown from his mobile home during the storm was in fair condition Sunday at Medical College of Georgia Hospital, said a hospital spokeswoman. The man's identity was not released Sunday. The Burke County Sheriff's Office referred questions about the man to Burke County's Emergency Management Agency. A message left there wasn't immediately returned Sunday.

Mr. Vaughan said he had heard about the Burke County case. He said the man's mobile home took a direct hit from a tornado and "We determined it went airborne for about 75 or 80 yards, hit the ground and probably rolled into some trees and proceeded to divide into two pieces."

He said a neighbor heard the man yelling for help a distance of about one to two football fields from the original location of the house.

"It's amazing he's still alive," Mr. Vaughan said.
