Tens of thousands of people displaced by storm Sandy could soon need housing as cold weather closes in, New York's political leaders have warned.
 
New York City Mayor Michael Bloomberg put the figure at 30,000-40,000 people.
 
Federal agencies are looking for flats and hotel rooms in order to get people out of shelters, Homeland Security Secretary Janet Napolitano has said.
 
At least 106 US deaths - 40 of them in New York City - have been blamed on Sandy, which struck on 29 October.
 
The storm had already caused 69 deaths in the Caribbean before reaching the US. On Sunday the Haitian government made an appeal for humanitarian assistance from other governments and international organisations.
 
Aid agencies in Haiti have voiced concerns about the damage caused by Sandy, which has destroyed crops and left thousands of people homeless. There are also fears about the spread of cholera in flooded areas.
