Hurricane Sandy, which weakened to a post-tropical cyclone when it made landfall in New Jersey late Monday, caused flooding in New York City and other coastal areas in the Northeast. At least 16 people were killed, and a 170-foot tanker was left on a Staten Island street after the storm surge in New York City receded. "It's sure shaping up to be a storm that will be historic in nature," said Louis Uccellini of the National Centers for Environmental Prediction.
