Deep freeze for US east coast after nor’easter brings thick snow

Massachusetts sees power outages in worst of storm, with dangerous wind chills following in its wake

The US east coast fell into a deep freeze on Sunday, after a powerful nor'easter dumped mounds of snow, flooded coastlines and knocked out power to tens of thousands.

Dangerous wind chills were expected after the storm dumped snow from Virginia to Maine. The weather may have contributed to at least four deaths in New York, all on Long Island.
