ATLANTA - The city dodged the first punch of a dangerous winter storm Tuesday, but forecasters warned of a potentially "catastrophic" second blow in a thick layer of ice that threatened to bring hundreds of thousands of power outages and leave people in their cold, dark homes for days.
The streets and highways in metro Atlanta were largely deserted as people in the South's business hub heeded advice from officials to hunker down at home, especially after the snow jam two weeks ago saw thousands of people stranded on icy, gridlocked roads for hours when 2 inches of snow fell.
"Last time I was totally unprepared, I was completely blindsided," said Lisa Nadir, of Acworth, who sat in traffic for 13 hours and then spent the night in her car when the storm hit Jan. 28. "I'm going to be prepared from now on for the rest of my life."
Vehicles slowly make their way on a snow-covered Alabama state Route 35, on Tuesday, in Fort Payne, Ala. Residents woke to a blanket of snow that was expected to continue throughout the morning hours.
Nadir was telecommuting from home Tuesday and she had kitty litter in her trunk in case she needed to put it down on icy roads for extra traction.
The forecast drew comparisons to an ice storm in the Atlanta area in 2000 that left more than 500,000 homes and businesses without power and an epic storm in 1973 that caused an estimated 200,000 outages for several days. In 2000, damage estimates topped $35 million.
Eli Jacks, a meteorologist with National Weather Service, said forecasters use words like "catastrophic" sparingly.
"Sometimes we want to tell them, 'Hey, listen, this warning is different. This is really extremely dangerous and it doesn't happen very often,'" Jacks said.
This kind of language was first used in May 1999 for a tornado in Moore, Okla. Forecasters called it a "tornado emergency" to make sure the public knew it was not a typical tornado.
"I think three-quarters of an inch of ice anywhere would be catastrophic," Jacks said.
But the Atlanta area and other parts of the South are particularly vulnerable because there are so many trees and limbs hanging over power lines. When the ice builds up on them, limbs snap and fall, knocking out power.
"There is no doubt that this is one of Mother Nature's worst kinds of storms that can be inflicted on the South, and that is ice. It is our biggest enemy," Georgia Gov. Nathan Deal said.
While only light rain fell in Atlanta on Tuesday, cities 40 miles northwest saw 2 to 3 inches of snow. The rain was expected to turn into sleet and freezing rain overnight.
