Longtime Washingtonians will remember the major impacts that occurred 11 years ago with Hurricane Sandy. It set several records in the nation’s capital and ranks as one of the costliest natural disasters in U.S. history. Sandy was the strongest hurricane of the 2012 hurricane season as a Category 3 storm with sustained winds of 115 mph and a minimum central air pressure of 940 millibars. It weakened considerably before its landfall in New Jersey as it moved over cooler water and into an increasingly unfavorable environment for a tropical storm or hurricane. Consequently, the structure of the storm changed and Sandy was declared a “non-tropical” or “post-tropical” storm, by the National Hurricane Center.
