New Jersey resident Ross Cocheo describes "complete devastation"
Businesses and services in the north-eastern US are reopening after two days of closure forced by the storm, Sandy.
Flights have resumed to airports in New York. Some federal offices and schools were working on Wednesday, and Wall Street is trading again.
But many homes still have no power and the New York subway remains shut. More than 40 people are dead.
President Barack Obama, who has put campaigning on hold, is due to visit affected areas in New Jersey.
The cost of clearing up after the storm has been estimated at $30-40bn (£18-24bn).
New York Governor Andrew Cuomo said: "We have not seen damage like this in a generation."
