Irene: Waters rise and fall in NYC harbour

As Tropical Storm Irene passed through New York, the BBC's Laura Trevelyan witnessed the storm surge at Battery Park.

Despite being downgraded from a hurricane, the storm still battered the city with fierce winds and rain.

These clips from Laura Trevelyan's reports show how quickly the waters rose and fell as the storm passed over.
