Across the street, others lined up to ask for help, with wish lists reflecting the extent of their needs: a car to replace one washed away; money for a family of five in a hotel; advice on rebuilding a business. Any sense that New York City was returning to normal 11 days after Superstorm Sandy was swept away Thursday after a nor’easter made a terrible situation nearly unbearable in areas still struggling to recover from Sandy. The new storm cut power to about 100,000 people and was blamed for the death of a man in Burlington, N.J. The freezing rain, sleet and snow — 9 to 12 inches fell in some areas — fell on those who are running out of patience.
