New York Mayor Michael Bloomberg says backup power has been lost at New York University hospital and the city is working to move people out.
The mayor delivered a news conference Monday night and said rain was tapering off in the city and the storm surge was expected to recede by midnight.
The hospital complex is near the East River in an area of lower Manhattan where flooding has been reported.
Bloomberg says a few parts of lower Manhattan still have power. He said there have been a large number of fires reported from downed power lines.
