US braces itself for more blizzards

A band of frigid weather snaking its way up the east coast of the United States threatens to bring blizzards and a foot of snow to New York City and New England, while several states to the South made emergency declarations as the storm caused crashes on slick roads.

Airlines grounded hundreds of flights today along the north-east corridor in anticipation of the storm, affecting major airports including New York's JFK and Newark.
