Sandy, the monster storm, slammed into the East Coast Monday, killing at least 16 people, sending a record-breaking 13-foot surge of seawater at New York City and knocking out power to an estimated 5.7 million people.

The massive storm was downgraded from a hurricane after it came ashore in southern New Jersey, bringing more than 85-mph winds and a roiling wall of seawater as it moved through New York City. It sent water pouring into two major commuter tunnels and into subway stations and tracks.

The deaths were reported in New Jersey, New York, West Virginia, Pennsylvania and Connecticut. Some of the victims were killed by falling trees. Police in Toronto said a woman was killed by a falling sign.
