In Rock Hill, a three-story home at 455 Old Pointe School Road was stuck by lightning, fire officials said.

"The neighbors said they heard a loud crack of lightning," said Rock Hill Fire Batallion Chief Steve Rogers. "They looked, but they didn't see anything."

Later, they discovered the house was burning. No one was injured. The owners were not home at the time, he said. Damage to the home was undetermined, he said, but most of the roof was gone and "upstairs is pretty much a loss."

Lyn Garris, spokeswoman for the city of Rock Hill, said hundreds of Rock Hill utilities customers experienced brief power outages. Affected neighborhoods included Bristol Parkway, Sunset Park, Norwood Ridge, Cato Estates, Shiland Hills, Shadowbrook and Oakwood Acres, she said.

Residents from Mount Gallant Road to the Catawba River also experienced sporadic outages. Power was expected to be restored by midnight, she said.

Almost 1,100 Duke Energy customers in York County -- mostly in the Fort Mill area -- lost power, said Richard Jiran, business relations executive with Duke Energy. No Duke Energy power outages were reported in Chester County, but 44 people were without power in Lancaster County, he said.

Officials with York Electric Cooperative could not be reached for comment.
