(CNN)  -- Storms that killed two people in northern Georgia spread Saturday night into South Carolina, where possible tornadoes downed trees, blew roofs off homes and broke power lines, weather forecasters said.



There was heavy damage in Prosperity, South Carolina, where residents reported seeing a tornado touch down, said Newberry County sheriff's Capt. Todd Johnson. Prosperity is 40 miles northwest of Columbia.



A woman was severely injured when a tree fell on her trailer, trapping her inside, Johnson said.



About 56,000 customers remained without power Sunday morning after storms swept through Savannah knocking out power while the coastal Georgia city was in the midst of its St. Patrick's Day celebrations,  said Carol Boatwright of Georgia Power.



Damage was reported Saturday night in the counties of Newberry, McCormick, Edgefield, Lexington, Aiken and Kershaw.



"We have numerous reports of tornadoes touching down. There is a lot of damage, and we are unable to respond to all of the calls," a dispatcher for the Aiken County Sheriff's Department said.



Meanwhile, the storm danger passed in the Atlanta, Georgia, area. A Friday night tornado packing winds of up to 135 miles per hour cut a path 6 miles long and 200 yards wide through downtown in less than 30 minutes.  Watch a flyover of a damaged area in Georgia »

Five dead dogs were found in a nearby field, and other injured animals were taken to an animal control agency, he said.

Saturday's severe weather followed an EF-2 tornado, with top winds of up to 135 mph that ripped through downtown Atlanta on Friday night. There were no fatalities, and only one serious injury was reported.



Rain, wind and hail caused additional power outages Saturday in the Atlanta area and triggered delays of more than an hour for flights leaving Hartsfield-Jackson International Airport, according to an airport spokesman. E-mail to a friend
