US President Barack Obama has been touring parts of New Jersey hit by the superstorm Sandy.
Along with state governor Chris Christie he flew over devastated coastal areas that bore the brunt when the weather system made landfall.
Almost six-million people are still without power in the north-east region of the US, and Governor Christie warned that it could be ten days before everyone is re-connected.
In neighbouring New York there are signs that life is slowly returning to normal. Subway trains are restarting services, though not yet in the southern part of Manhattan.
The city’s mayor has said most bridges and tunnels will only be open to vehicles carrying three or more people.
Some estimates put the cost of the damage at 15-billion euros.
