NEW YORK, NY. (AP) -- New York Gov. Andrew Cuomo says today that cold temperatures will leave "tens of thousands" of people whose homes have been damaged by the superstorm 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.

Latest figures put some 730,000 residents in the NY region without power. While trains and subways are nearly fully operational, Gov Cuomo says commuters should expect delays, as schools in the area reopen for business, many after being closed for a week.

Hurricane Sandy made landfall earlier this week and caused devestation along a large portion Eastern Seaboard of the United States. Thousands remain without even the basics as rescue crews work to provide food, shelter and other necessities for the people in areas affected by the superstorm.
