A perfect storm

This image, taken by the GOES-13 satellite on October 26, shows Hurricane Sandy as it passes over the Bahamas. The lines of clouds seen on the left, moving east across the United States, represent a cold front. The several weather systems coming together prompted talk of particularly volatile conditions that led to the situation being "Frankenstorm."

The National Hurricane Center warned Sunday that Sandy is expected to bring "life-threatening storm surge flooding" to the Mid-Atlantic coast including Long Island Sound and New York Harbor, with winds expected to be near hurricane force at landfall.

Storm surge in the Long Island sound is expected to be between 6 and 11 feet.
