WEST CALDWELL, N.J. – The nor’easter that swept through the Northeast on Wednesday night dumped record snow, hampered efforts to recover from Superstorm Sandy and has been linked to at least one death.

From New Jersey to New York, roads, trees and homes were blanketed in overnight snow and another 100,000 households lost power, adding to the misery in a region still grappling with widespread storm damage.

The bad weather and white-out conditions prompted major airlines to cancel hundreds of flights, most in the New York area, although airports in Boston, Philadelphia, Washington, D.C., and elsewhere are affected, according to flight tracking service FlightAware.
