Snow and ice shut down most streets and freeways in the greater Atlanta area.

The mad rush began at the first sight of snow: Across the Atlanta area, schools let out early and commuters left for home after lunch, instantly creating gridlock so severe that security guards and doormen took to the streets to direct cars amid a cacophony of blaring horns.

Highways surrounding the city that rarely sees snow were converted into treacherous paths of ice Tuesday, causing hundreds of cars to slide off the road, slam into each other, or crawl bumper to bumper in gridlock. Children were stranded at schools with their teachers, while Gov. Nathan Deal made a late-night announcement that he would send state troopers to rescue them.

Deal said state and local officials also would try to rescue those stranded along highways that were at a standstill even close to midnight.

The rare Southern winter storm dropped more than 3 inches of snow in some areas of north Georgia, while 2.3 inches were recorded at Hartsfield Jackson International Airport after hours of snowfall Tuesday afternoon and evening, said National Weather Service meteorologist Ryan Willis.

While such amounts barely qualify as a storm in the north, it was enough to paralyze the Deep South. Many folks across the region don't know how to drive in snow, and many cities don't have big fleets of salt trucks or snowplows, and it showed. Hundreds of wrecks happened from Georgia to Texas. Two people died in an accident in Alabama.

In Atlanta, the gridlock was so bad, a baby girl was delivered alongside Interstate 285, said Capt. Steve Rose, a spokesman for Sandy Springs police in suburban north Atlanta. He said an officer made it to the mother and her husband in time to help with the delivery, which he described as "flawless." There were no complications and the family was taken to a hospital.
