The first major winter storm of 2014 created havoc in the northeastern United States Friday, bringing heavy snowfall, strong winds and dangerously cold temperatures to the region.
The storm forced the cancellation of thousands of flights Thursday and Friday and prompted the governors of New York and New Jersey to declare states of emergency.
Boston was the hardest-hit city, with up to 35 centimeters of snow, while towns to the north got almost double that amount.
Wind chill temperatures across a wide swath of the northeast were expected to plummet below minus 20 degrees Celsius, prompting the National Weather Service to warn of the risk of hypothermia and frostbite. In Philadelphia, a worker was reported killed when a pile of de-icing salt fell on him.
The storm represented the first big test for New York City's newly-elected mayor, Bill de Blasio, who dispatched hundreds of plows and salt spreaders to the streets of the nation's largest city.
Meanwhile, the upper Midwest remained in a deep freeze, with temperatures as low as minus 41 degrees Celsius settling over much of the region.
