Hurricane Sandy slammed into the east coast of the United States and Canada on Tuesday, killing at least 13 people as the monster storm toppled trees, structures and cut off electricity in many states.
The US National Hurricane Center (NHC) had said that the storm could bring a "life-threatening storm surge", and forecasters warned of more disaster, forcing state authorities to order mandatory evacuation in coastal and low-lying areas.
The death toll has risen to 13 - five in New York, two in Morris County, New Jersey, two in Pennsylvania, one each in Maryland and West Virginia, and one in Toronto, Canada, according to AFP report.
A US sailor, found on board a replica of the HMS Bounty, died at the hospital and the captain of the ship is also feared dead.

Hurricane Sandy killed 69 people in the Caribbean last week.
John Miksad, senior vice-president at Consolidated Edison, said in a news briefing that at least 6.6 million people in New York were left without electricity on Monday night due to a planned power shut-down and an explosion at a substation suspected to have been caused by the storm.
It is reported that around 200 patients from NYU Langone Hospital were evacuated to other hospitals after the backup generator failed.
The Metropolitan Transportation Authority Chairman Joseph J. Lhota said in a statement that Hurricane Sandy was the worst disaster to have happened to the 108-year-old New York City subway system.
"The New York City subway system is 108 years old, but it has never faced a disaster as devastating as what we experienced last night. Hurricane Sandy wreaked havoc on our entire transportation system, in every borough and county of the region. It has brought down trees, ripped out power and inundated tunnels, rail yards and bus depots. As of last night, seven subway tunnels under the East River flooded. Metro-North Railroad lost power from 59th Street to Croton-Harmon on the Hudson Line and to New Haven on the New Haven Line. The Long Island Rail Road evacuated its West Side Yards and suffered flooding in one East River tunnel. The Hugh L. Carey Tunnel is flooded from end to end and the Queens Midtown Tunnel also took on water and was closed. Six bus garages were disabled by high water," said Lhota in a statement.
"We are assessing the extent of the damage and beginning the process of recovery. Our employees have shown remarkable dedication over the past few days, and I thank them on behalf of every New Yorker. In 108 years, our employees have never faced a challenge like the one that confronts us now. All of us at the MTA are committed to restoring the system as quickly as we can to help bring New York back to normal," he added.
"We have not seen the kind of flooding problems that certainly could have happened thus far, but we've still got a long ways to go to get through this storm," Washington Mayor Vincent Gray said on local television.
The National Hurricane Center said in its "post-tropical cyclone sandy forecast" that the superstorm is still packed with hurricane-force winds.
"There are no coastal tropical cyclone warnings in effect. However...there are non-tropical high-wind warnings in effect for portions of the mid-atlantic and new England states," the NHC advisory said at the time of filing this report.
"Hurricane-force wind gusts are possible along portions of the coast between chincoteague virginia and chatham massachusetts during the next few hours. This includes the tidal potomac from Cobb island to smith point...the middle and upper Chesapeake bay...Delaware bay...and the coasts of the northern Delmarva peninsula...New Jersey...the New York city area...Long Island...Connecticut...and Rhode island.
"Tropical-storm-force winds are expected to continue north of Chatham through much of new England...and over the lower chesapeake bay...and south of Chincoteague to extreme northeastern north Carolina," NHC added.
