ATLANTA (AP) - The second wintry storm in two weeks to hit the Deep South encrusted highways, trees and power lines in ice Wednesday, knocking out electricity to nearly a half-million homes and businesses.
But it didn't wreak the highway havoc in Atlanta that the previous bout of heavy weather did - largely because people learned their lesson the last time and stayed off the roads.
At least nine traffic deaths across the region were blamed on the treacherous weather, and nearly 3,300 airline flights nationwide were canceled.
As residents across the South heeded forecasters' unusually dire warnings and hunkered down at home against the onslaught of snow and freezing rain, the storm pushed northward along the Interstate 95 corridor, threatening to bring more than a foot of snow Thursday to the already sick-of-winter mid-Atlantic and Northeast.
Forecasters warned of a potentially "catastrophic" storm across the South with more than an inch of ice possible in places. Snow was forecast overnight, with up to 3 inches possible in Atlanta and much higher amounts in the Carolinas.
As the day wore on, power outages climbed and the dreary weather came in waves.
Ice combined with wind gusts up to 30 mph snapped tree limbs and power lines. More than 200,000 homes and businesses lost electricity in Georgia, while South Carolina had about 245,000 outages. Some people could be in the dark for days.
As he did for parts of Georgia, President Barack Obama declared a disaster in South Carolina, opening the way for federal aid. In Myrtle Beach, S.C., palm trees were covered with a thick crust of ice.
In Atlanta, which was caught unprepared by the last storm, streets and highways were largely deserted this time. Before the first drop of sleet even fell, area schools announced they would be closed on Tuesday and Wednesday. Many businesses in the corporate capital of the South shut down, too.
The scene was markedly different from the one Jan. 28, when thousands of children were stranded all night in schools by less than 3 inches of snow and countless drivers abandoned their cars after getting stuck in bumper-to-bumper traffic for hours and hours.
However, traffic backed up on highways in Charlotte and Raleigh, N.C., and commutes that normally take minutes turned into hours-long ordeals.
Caitlin Palmieri drove two blocks from her job at a bread store in downtown Raleigh before getting stuck. She left her car behind and walked back to work.
"It seemed like every other car was getting stuck, fishtailing, trying to move forward," she said.
Across the region, those who had power passed the time watching movies or surfing the Internet. Matt Altmix walked his Great Dane, Stella, in Atlanta because "even in the snow, you still have to do your business."
"I think some folks would even say they were a little trigger-happy to go ahead and cancel schools yesterday, as well as do all the preparation they did," Altmix said. "But it's justified."
Georgia Gov. Nathan Deal, who was widely criticized over his handling of the last storm, sounded an upbeat note this time.
"Thanks to the people of Georgia. You have shown your character," he said.
Deal said four students, ages 11 to 18, from the Georgia Academy for the Blind in Macon were back home in metro Atlanta after hitching a ride with the Georgia National Guard before the worst of the storm hit. Their parents were unable to make the drive, which is 80 or 90 miles one way.
North Carolina Gov. Pat McCrory urged people to charge their cellphones and find batteries for radios and flashlights because the storm could bring nearly a foot of snow in places such as Charlotte.
"Stay smart. Don't put your stupid hat on at this point in time. Protect yourself. Protect your family. Protect your neighbors," McCrory said.
Kathy Davies Muzzey of Wilmington, N.C., said she hid the car keys from her husband, John, on Tuesday night because he was thinking about driving to Chapel Hill for the Duke-UNC basketball game. He has missed only two games between the rivals since he left school in the late 1960s.
"He's a fanatic - an absolute fanatic," she said.
For the mid-Atlantic and the Northeast, the heavy weather was the latest in an unending drumbeat of storms that have depleted cities' salt supplies and caused school systems to run out of snow days.
The nation's capital could get up to 8 inches of snow. New York City could see 6 inches. Other sections of eastern New York were expecting 10 to 14 inches.
In Atlanta, stinging drops of sleet fell and windshields were crusted over with ice. Slushy sidewalks made even short walks treacherous. One emergency crew had to pull over to wait out the falling snow before slowly making its way back to the Georgia Emergency Management Agency's operations center.
In normally busy downtown areas, almost every business was closed except for a pharmacy.
Amy Cuzzort, who spent six hours in her car during the traffic standstill of January's storm, said she would spend this one at home, "doing chores, watching movies - creepy movies, 'The Shining'" - about a writer who goes mad while trapped in a hotel during a snowstorm.
In an warning issued early Wednesday, National Weather Service called the storm "catastrophic ... crippling ... paralyzing ... choose your adjective."
Meteorologist Eli Jacks noted that three-quarters of an inch of ice would be catastrophic anywhere.
However, the South is particularly vulnerable: Many trees are allowed to hang over power lines for the simple reason that people don't normally have to worry about ice and snow snapping off limbs.
Three people were killed when an ambulance careened off an icy West Texas road and caught fire. A chain-reaction crash shut down the four-lane Mississippi River bridge on Interstate 20 at Vicksburg, Miss., and a tanker leaked a corrosive liquid into the river. No one was injured.
On Tuesday, four people died in weather-related traffic accidents in North Texas, including a Dallas firefighter who was knocked from an I-20 ramp and fell 50 feet. In Mississippi, two traffic deaths were reported.
