Nathan Waters, a spokesman with the Tennessee Division of Forestry, said late Sunday night that the fire had jumped Lost Branch Road and was threatening more cabins.

"There's hundreds of cabins and rentals up here," Waters said. "They are so close together they are going up like dominoes. Just one after the other."
