The east coast of the United States is bracing itself for Sandy, the storm that killed more than 40 people in the Caribbean.

Sandy combines elements of a tropical cyclone and a winter storm.

A number of states, including New York and Pennsylvania, have declared a state of emergency and have urged residents to stock up with food and water.

New York City Mayor Michael Bloomberg said nobody really knew what the storm will do next.
