Hurricane Andrew
Post-analysis on Andrew revealed that the storm was often stronger than operationally reported between early on August 22 and early on August 26. In real time, the National Hurricane Center assessed its peak intensity as , which was upgraded to 155 mph (250 km/h) in a post-storm analysis after the season ended. However, a 2004 paper by Christopher Landsea and others concluded that Andrew became a Category 5 hurricane near the Bahamas on August 23 and reached maximum sustained winds of 175 mph (280 km/h). The paper also indicated that Andrew briefly re-intensified into a Category 5 hurricane around the time of landfall in South Florida early on August 24. The storm was found to have been slightly stronger while approaching Louisiana, but the landfall winds were decreased from 120 mph (195 km/h) to 115 mph (185 km/h).
1863 Atlantic hurricane season
Although it is not officially listed in HURDAT, Hurricane Amanda, named after a ship run aground by the storm, developed in the Gulf of Mexico on May 24. First documented in 2013 by Michael Chenoweth and Cary Mock, the system capsized several other ships and caused damage along the coast of the Florida Panhandle. The cyclone made landfall near Apalachicola, Florida exceptionally early in the season, on May 28. Amanda holds the distinction of being the only known hurricane landfall in the United States in the month of May since HURDAT records began in 1851. On land and at sea, the cyclone left at least 110 fatalities. Few other storms were notable. In August, the third official storm capsized the American brig "Bainbridge" off Hatteras, North Carolina, drowning 80 people. The seventh official cyclone caused 10 deaths near Tampico, Tamaulipas, after the ship "J.K.L." sunk.
