Three people have been killed in car crashes as a powerful snowstorm sweeps across the east coast of the United States.
Snow warnings are in place for much of the eastern seaboard with more than 50 million people braced for outages and treacherous conditions on the roads.
Up to two feet (60cm) of snow is predicted to fall in some parts, with around 18 inches – two inches per hour – expected from central Pennsylvania into southern New York and New England.
The National Weather Service said the storm was “set to bring an overabundance of hazards from the mid-Atlantic to the northeast”.
This includes freezing rain and ice in the mid-Atlantic, heavy snow in the New York City area and southern New England, strong winds with gusts up to 50mph (80kmph) and coastal flooding, as well as severe thunderstorms and even some tornadoes.
Officials throughout the area urged motorists to stay off the roads and residents to stay at home, and some bus and rail services have been suspended.
A crash in Pennsylvania killed two people and involved dozens of vehicles on a major road on Wednesday afternoon, police said, while issuing a reminder to only travel if “absolutely necessary”.
