New York Gov. Andrew Cuomo says cold temperatures will leave “tens of thousands” of people whose homes have been damaged by Superstorm Sandy needing other places to live.

He says “it’s going to become increasingly clear” that homes without heat are uninhabitable as temperatures drop. He says that means that residents who have been reluctant to leave their homes will have to, and that they’ll need housing.

New York City Mayor Michael Bloomberg says the city expects that it will have to find housing for 30,000 to 40,000 people.
