Forsyth County Sheriff Ted Paxton said storms are believed to have knocked out the system. Paxton said the county is using its mobile command center and also getting help from Hall County's 911 center to relay emergency calls.
The storm system that rolled through Forsyth County, also sent a lightning bolt crashing onto an Atlanta hotel rooftop, injuring a worker Thursday afternoon.
The man was washing windows at the top of the Marriott Marquis hotel in downtown Atlanta when the lightning hit. He was taken to Grady Memorial Hospital. His condition wasn't known.
