Sandy made landfall at 8 p.m. near Atlantic City, which was already mostly under water and saw an old, 50-foot 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.

Much of New York was plunged into darkness Monday by a superstorm that overflowed the city's historic waterfront, flooded the financial district and subway tunnels and cut power to nearly a million people.
