Millions of people in the US eastern seaboard are waking to a thick blanket of snow that has paralysed transport links in New York and Washington DC.
As householders dug themselves out of drifts up to 40in (102cm) deep, the hazards of shovelling snow were brought home by at least six deaths.
A further 12 people have died in other snow-related incidents since Friday.
The storm, dubbed Snowmageddon and Snowzilla on social media, is lessening and heading for the Atlantic Ocean.
It has affected some 85 million people, cutting power to 200,000 people.
However, many took to the streets and parks to enjoy the snow, with a giant snowball fight breaking out on Times Square, New York.
