What could be the biggest storm in 100 years in expected to make landfall in New Jersey late Monday night.

Hurricane Sandy could merge with a winter storm out of the west to become a new perfect storm, as bad as the deadly New England hurricane of 1938. It was called a Frankenstorm, though National Weather Service has refrained from this nickname due to the severity of its forecast.

Despite Sandy's record strength, damages may be relatively low (compared to the worst storms in history) at $1 billion, estimates Weather Underground's Jeff Masters.

New York, New Jersey, Connecticut, Pennsylvania, Maryland, Virginia, Vermont, Massachusetts, Rhode Island, and DC have all declared states of emergency in advance of Hurricane Sandy, with limited states of emergency elsewhere.

Around 10 million people could lose power, estimates Johns Hopkins engineer Seth Guikema.
