Tourists enjoy shorts weather in New York

In the movies, New York is always cold and covered in snow at Christmas - but this season it's an unseasonably warm and wet wonderland.

Hundreds of record highs are expected to be hit on Christmas Eve and Christmas Day across eastern parts of the US and Canada, with temperatures forecast as high as 77F (25C) in Georgia, 75F further north in Washington, and 15C (59F) in Toronto.
