A state of emergency has been declared in North Carolina, with some areas reporting as much as 0.5m (18.5ins) of snow over the weekend.
One man died after a tree fell on his car. A search is under way for a driver whose vehicle was found in a river.
Thousands of flights were also cancelled across the region.
‘A dangerous system’ More than 300,000 people were affected by electricity outages in the Carolinas, Alabama, Tennessee and Georgia on Sunday, while storm warnings remained in place in the south-east “especially North Carolina and Virginia”, the National Weather Service (NWS) said in a tweet.
The storm was expected to move off the coast on Monday, although the NWS’s lead forecaster Michael Schichtel warned it would continue to be “a dangerous system”.
“It’s slow to move off the Carolinas but a saving grace is that it won’t hit New England,” he told Reuters news agency. In some areas, so much snow fell the weight brought power lines crashing down.But the main danger appeared to be on the roads.
Almost 60 crashes were reported in Virginia, state police told local media, with the number rising to 500 in North Carolina between midnight and 11:00 local time on Sunday. As a result, North Carolina Governor Roy Cooper told CNN the state’s “biggest concern” was not the snow but “ice making roads even more dangerous”.But the main danger appeared to be on the roads.
