Hurricane Sandy (unofficially known as "Superstorm Sandy") was the deadliest and most destructive hurricane of the 2012 Atlantic hurricane season, and the second-costliest hurricane in United States history. Classified as the eighteenth named storm, tenth hurricane and second major hurricane of the year, Sandy was a Category 3 storm at its peak intensity when it made landfall in Cuba. While it was a Category 2 storm off the coast of the Northeastern United States, the storm became the largest Atlantic hurricane on record (as measured by diameter, with winds spanning 1,100 miles (1,800 km)). Estimates as of 2015 assessed damage to have been about $75 billion (2012 USD), a total surpassed only by Hurricane Katrina. At least 233 people were killed along the path of the storm in eight countries.
Sandy developed from a tropical wave in the western Caribbean Sea on October 22, quickly strengthened, and was upgraded to Tropical Storm Sandy six hours later. Sandy moved slowly northward toward the Greater Antilles and gradually intensified. On October 24, Sandy became a hurricane, made landfall near Kingston, Jamaica, re-emerged a few hours later into the Caribbean Sea and strengthened into a Category 2 hurricane. On October 25, Sandy hit Cuba as a Category 3 hurricane, then weakened to a Category 1 hurricane. Early on October 26, Sandy moved through the Bahamas. On October 27, Sandy briefly weakened to a tropical storm and then restrengthened to a Category 1 hurricane. Early on October 29, Sandy curved north-northwest and then moved ashore near Brigantine, New Jersey, just to the northeast of Atlantic City, as a post-tropical cyclone with hurricane-force winds.
On August 28, 2005, Hurricane Katrina was in the Gulf of Mexico where it powered up to a Category 5 storm on the Saffir-Simpson hurricane scale packing winds estimated at 175 mph.
At 7:10 a.m. EDT on August 29, Hurricane Katrina made landfall in southern Plaquemines Parish Louisiana, just south of Buras, as a Category 3 hurricane. Maximum winds were estimated near 125 mph to the east of the center.
According to National Weather Service Mt. Holly meteorologist Gary Szatkowski, the thunderstorm that devasted Atlantic County Saturday June 30, 2012 is "a rare type of thunderstorm system called a derecho, which is a “super organized group of thunderstorms. "
