Hurricanes, Dearing said, actually offer better preparation time than other natural or man-made disasters that come without warning. Dearning compared forecasts of hurricane Sandy to Irene in 2011, which is the fifth costliest storm in U.S. history and 1991's Hurricane Bob, which at the time was among the ten costliest hurricanes in the U.S.

Hurricane Irene struck in Aug., 2011, brushing along the Mid-Atlantic until making its final landfall Brooklyn. Irene caused massive flooding and widespread wind damage, causing 56 deaths and leaving millions without power. It was estimated to have cause around $15.6 billon in damage.

In July 1991, after brushing past North Carolina's Outer Banks, Long Island in New York, Hurricane Bob made landfall on Rhode Island, and eventually caused $1.5 billion in damage to the upper Northeast including 17 deaths.
