Sandy's surge blasts into lower Manhattan

Andrew Kelly / Reuters A deluge floods the Brooklyn-Battery tunnel in Manhattan as Hurricane Sandy made its approach in New York on Monday. By Isolde Raftery, NBC News Storm water flooded parts of lower Manhattan on Monday night, pouring into the Brooklyn-Battery tunnel, bursting into a subway station and even cascading into the construction site at Ground Zero.  Superstorm Sandy made landfall in New Jersey, but its wide wingspan crossed the Tri-State area, shutting off power to 3.6 million in the region and forcing the residents of the nation's biggest city to stay indoors. Most of Manhattan below 39th Street was without power, Con Edison spokesman Bob McGee told NBCNewYork.com. New York City's Office of Emergency Management sent out blast alerts to phones across the city: "Go indoors immediately and stay inside. DO NOT DRIVE." Mayor Michael Bloomberg spoke directly to New Yorkers, emphasizing that those who didn't leave when the warnings were issued now stay put, stay away from windows and close the drapes. "The time to leave has passed," Bloomberg said. "Do not go outside. It is dangerous." He told limo and taxi drivers to stay off the road.

That's short of the 375,000 people who live within six and seven feet of sea level and who were ordered to leave the city but instead chose to hunker down in their homes. At Battery Park at the southern tip of Manhattan, the water level rose to a record-breaking 13.5 feet. The previous record was 11.2 feet, set in 1821. Photos posted to social media told the story: A haunting image of a lit carousel halfway submerged in Brooklyn; what appeared to be a waterfall pouring into a parking garage, running over cars; water gushing into a subway station and past the turnstiles. One photo provided by The Associated Press showed water running down into a construction site at Ground Zero. On Staten Island, rescuers responded in boats at the water line rose, reaching the attics of some homes, NBCNewYork.com reported. Reports from Coney Island and Brighton Beach indicated that ocean water had started making its way through the streets. Lucas Jackson / Reuters Superstorm Sandy made landfall Monday evening on a destructive and deadly path across the Northeast. A New York Times story from September discussed what might happen to New York if struck by a storm stronger than Hurricane of Irene during August 2011. Ultimately, Irene "weakened to a tropical storm and spared the city, but it exposed how New York is years away from – and billions of dollars short of – armoring itself," the story said. It continued: The most vulnerable systems, like the subway tunnels under the Harlem and East Rivers, would have been unusable for nearly a month, or longer, at an economic loss of about $55 billion, said Dr. Jacob, an adviser to the city on climate change and an author of the 2011 state study that laid out the flooding prospects.
