An arctic chill has gripped the northeastern United States. In Boston, coastal flooding hit some communities causing many homes to become submerged in flood water.
The forecast overnight low for Boston was a teeth-chattering minus 20 Celsius while New York hit minus 16 Celsius.
More than 3,000 US flights were cancelled on Friday, another 12,000 delayed on Friday.
Schools and offices across the region closed, extending the holiday break for tens of thousands.
The first major storm of the new year hit as many were getting ready to head home after the holidays.
