WEST CALDWELL, N.J. – The storm 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.

Parts of Connecticut saw more than a foot of snow overnight — a record — while New Jersey and New York saw up to 9 inches in some cities.

Late Wednesday, a man was killed in a fatal crash on a highway in Burlington, N.J., according to State Police Sgt. Adam Grossman.

“The state and the residents are still trying to clean up and get back to normal life,” Grossman said.

The snow and frigid temperatures intensified suffering in hard-hit Sandy towns, including Little Egg Harbor, N.J., where mountains of debris stood frozen in front of storm-damaged homes.

“We have been fighting to get these massive piles out of the streets so we could get utility crews in here,” Police Chief Richard Buzby said.

“But the storm hit us before we could get to many more areas,” he said.
