ATLANTIC CITY, N.J. (CBS NEWS) -- Superstorm Sandy slammed into the New Jersey coastline with 80 mph winds Monday night and hurled an unprecedented 13-foot surge of seawater at New York City, threatening its subways and the electrical system that powers Wall Street. At least 11 deaths were blamed on the storm, which brought the presidential campaign to a halt a week before Election Day.
Sandy knocked out power to at least 3.1 million people, and New York's main utility said large sections of Manhattan were plunged into darkness. Water pressed into the island from three sides.
Just before its center reached land, the storm was stripped of hurricane status, but the distinction was purely technical, based on its shape and internal temperature. It still packed hurricane-force wind, and forecasters were careful to say it remained every bit as dangerous to the 50 million people in its path.
As the storm closed in, it smacked the boarded-up big cities of the Northeast corridor — Washington, Baltimore, Philadelphia, New York and Boston — with stinging rain and gusts of more than 85 mph. It also converged with a cold-weather system that turned it into a superstorm, a monstrous hybrid consisting not only of rain and high wind but snow.
Sandy made landfall at 8 p.m. near Atlantic City, which was already mostly under water and saw a piece of its world-famous Boardwalk washed away earlier in the day.
Authorities reported a record surge 13 feet high at the Battery at the southern tip of Manhattan, from the storm and high tide combined.
In an attempt to lessen damage from saltwater to the subway system and the electrical network beneath the city's financial district, New York City's main utility cut power to about 6,500 customers in lower Manhattan. But a far wider swath of the city was hit with blackouts caused by flooding and transformer explosions.
The subway system was shut down Sunday night, and the stock markets never opened at all Monday. They are likely to be closed Tuesday as well.
The surge hit New York City hours after a construction crane atop a luxury high-rise collapsed in the wind and dangled precariously 74 floors above the street. Forecasters said the wind at the top the building may have been close to 95 mph.
As the storm drew near, airlines canceled more than 12,000 flights, disrupting the plans of travelers all over the world.
Storm damage was projected at $10 billion to $20 billion, meaning it could prove to be one of the costliest natural disasters in U.S. history.
The 11 deaths were in New Jersey, New York, Maryland, Pennsylvania and Connecticut. Some of the victims were killed by falling trees.
