The second wintry storm in two weeks to hit the normally warm U.S. South encrusted the region in ice, knocking out electricity to hundreds of thousands of homes and businesses before pushing toward the heavily populated Northeast.
At least 11 deaths across the region were blamed on the treacherous weather Wednesday, including three people who were killed when an ambulance careened off an icy Texas road and caught fire.
Nearly 3,300 airline flights nationwide were cancelled.
In an warning issued early Wednesday, National Weather Service called the storm "catastrophic ... crippling ... paralyzing ... choose your adjective."
Forecasters warned of more than 2.5 centimetres of ice possible in places. Snow was forecast overnight, with up 7.6 centimetres possible in Atlanta and much higher amounts in the Carolinas.
President Barack Obama declared a disaster in South Carolina and for parts of Georgia, opening the way for federal aid. In Myrtle Beach, South Carolina, palm trees were covered with a thick crust of ice.
The storm didn't cause the widespread highway problems in Atlanta that the last storm did, largely because people had learned their lesson. Streets and highways were largely deserted.
The storm then moved northward, threatening to bring more than 30 centimetres of snow Thursday to the mid-Atlantic and Northeast.
Washington D.C. could get up to 20 centimetres of snow. New York City could see 15 centimetres.
Federal offices in the Washington, D.C., area will be closed on Thursday, the government announced late Wednesday.
Ice combined with wind gusts up to 48 kilometres/hour snapped tree limbs and power lines. More than 200,000 homes and businesses lost electricity in Georgia, 130,000 in South Carolina and nearly 30,000 in Louisiana. Some people could be in the dark for days.
Atlanta was caught unprepared by the last storm on Jan. 28, when thousands of children were stranded all night in schools by less than eight centimetres of snow and countless drivers abandoned their cars.
Rescue workers in western India are working to locate survivors of a landslide that has claimed at least 30 lives and buried up to 200 people.
