WASHINGTON - Another round of snowy and icy weather led to school closures, dangerous driving conditions and power outages on Thursday across the south of the United States and even delayed a Georgia execution.

A mix of snow, sleet and freezing rain fell across the Gulf Coast states, the Carolinas and the DC area, Associated Press (AP) reported. This may also result in severe thunderstorms in parts of Georgia and Florida, the news agency quoted forecasters as saying.

Parts of northern Alabama have already seen more than 10 inches of heavy and wet snow, causing power outages. A wide area of north Alabama was shut down because of dangerous travel conditions, AP reported.

Schools were closed and states of emergencies were declared in the south ahead of the storm.

In Georgia, the execution on Wednesday of a woman was put off for several days because of the winter storm and "associated scheduling issues," AFP quoted authorities as saying.

Kelly Gissendaner, 46, who was convicted for killing her husband, had been set to die by lethal injection at 7.00 pm local time on Wednesday at a prison in Jackson, south of Atlanta, becoming the first woman to be executed in Georgia in 70 years.

Her execution had been delayed till the same time on Monday, AFP reported.

Georgia Governor Nathan Deal had declared a state of emergency and the closure of school and government offices.

Snow also fell on the Deep South on Wednesday as another storm brought nasty weather to the region, battering places that were hit hard just last week.

Relief, in the form of higher temperatures, is expected later on Thursday, according to Associated Press.
