Video: New York awakes to Superstorm Sandy damage Superstorm Sandy has left New York City's subway system underwater, shuttered financial markets and hundreds of thousands of people without power after a wall of seawater and high winds slammed into the city on Monday night. Where usually bustling crowds and traffic jams occupied the streets and underground, today they were largely empty. And high above midtown Manhattan, the broken boom of a crane continued to dangle precariously over a neighborhood. At least 33 people are believed to have died in the storm, with Mayor Michael Bloomberg reporting that in his city of New York alone, ten people had been killed.
