Biggest threat from Frankenstorm: Too much water

KENSINGTON, Md. - Meteorologists and disaster experts say water is what worries them most with the upcoming monster storm, spawning from Hurricane Sandy.

They said Sunday that water threatens the most lives and is likely to cause substantial property damage. They fear storm surge amped by waves and the full moon. Up to a foot of rain should trigger inland and flash flooding.

National Hurricane Center Director Rick Knabb says the storm's size means some coastal parts of New York and New Jersey can see water rise up to 11 feet above ground from surge and waves. The rest of the coast north of Virginia can see up to 8 feet of surge. New York will close its subways starting Sunday evening.

He says millions of people may be harmed by inland flooding.
