ATHENS, GEORGIA – In the waning weeks of the North American hurricane season – a time when a superstorm is not expected to cause widespread damage to the eastern coast of the United States – Hurricane Sandy is a grim reminder of the menace of extreme weather events. With the lowest central pressure of the 2012 hurricane season, Sandy may have caused up to $20 billion in damages, making it one of the costliest superstorms in history.
Sandy interacted with a weather system moving toward it from the east, posing difficult challenges for forecasters and nearly unprecedented weather conditions for the region. A similar storm hit New England 20 years ago. But Sandy was worse, delivering hurricane-strength winds, drenching rains, and severe coastal flooding throughout the populous mid-Atlantic and northeast corridor.
