A travel ban in New York City has ended as the eastern US begins digging out from the weekend’s massive snowstorm.
New York, the most populated city in the US, saw its second-highest snowfall since records began in 1869, Mayor Bill de Blasio said.
As five states saw snowfall of three feet (91cm) or more, the hazards of shovelling snow were brought home by at least six deaths.
A further 14 people have died in other snow-related incidents since Friday.
Media in New Jersey said a mother and her year-old son died of carbon monoxide poisoning late on Saturday.
Police said the exhaust pipe of the car in which they were sitting was covered by snow, adding that the woman’s three-year-old daughter is critically ill.
The storm, dubbed Snowmageddon and Snowzilla, is weakening and heading for the Atlantic Ocean.
It has affected some 85 million people, cutting power at one point to 300,000 people. The heaviest fall was recorded in Glengary, West Virginia, which had 42ins (107 cm).
