5 reasons why Sandy is expected to be a superstorm

(Continued)

4. HIGH TIDES COULD WORSEN FLOODING

Further complicating matters is the possibility for dangerous storm surges: A full moon means the tides will be higher than usual, which will make it easier for the storm's powerful winds to push water into low-lying areas. That, coupled with the threat of several inches of rain, has officials working to shore up flood defenses.

Storm surge could reach 4 to 8 feet from Maryland to Rhode Island, forecasters say. And inland river flooding is also a major concern, federal officials said Sunday.

5. COMBO OF SNOW, WIND INCREASES RISK FOR WIDESPREAD POWER OUTAGES

Storms in recent years have left hundreds of thousands of people in the eastern U.S. without power, sometimes for days at a time. Utilities have been bringing in extra crews and lining up tree trimmers so they're prepared, and with good reason. The superstorm brings two possibilities for knocking out electricity. For one, hurricane-force winds of at 74 mph could send tree branches into power lines, or even topple entire trees and power poles. Those left standing could succumb to snow, which could weigh down still-leafy branches enough to also topple trees.
