The 1935 Labor Day Hurricane was an extremely powerful and devastating Atlantic hurricane that struck the southeastern United States in early September 1935. For several decades it was: the most intense Atlantic hurricane on record in terms of barometric pressure, until surpassed by Hurricane Gilbert in 1988; the strongest Atlantic hurricane on record in terms of 1-minute sustained winds, until surpassed by Hurricane Allen in 1980; and the strongest at landfall by 1-minute sustained winds, until it was tied by Hurricane Dorian in 2019. The fourth tropical cyclone, third tropical storm, second hurricane, and second major hurricane of the 1935 Atlantic hurricane season, it is one of four Category 5 hurricanes on record to strike the contiguous United States, along with Hurricane Camille (1969), Hurricane Andrew (1992), and Hurricane Michael (2018).

Hurricane Allen was a rare and extremely powerful Cape Verde hurricane that affected the Caribbean, eastern and northern Mexico, and southern Texas in August 1980. The first named storm and second tropical cyclone of the 1980 Atlantic hurricane season, it was the fifth most intense Atlantic hurricane on record in terms of barometric pressure, behind Hurricane Rita, the 1935 Labor Day hurricane, Hurricane Gilbert and Hurricane Wilma. It was one of the few hurricanes to reach Category 5 status on the Saffir–Simpson Hurricane Scale on three occasions, and spent more time as a Category 5 than all but two other Atlantic hurricanes. Allen is the only hurricane in the recorded history of the Atlantic basin to achieve sustained winds of 190 mph, thus making it the strongest Atlantic hurricane by wind speed. Until Hurricane Patricia in 2015, these were also the highest sustained winds in the Western Hemisphere. Hurricane Allen was also the second strongest tropical cyclone to hit the Gulf of Mexico, with the strongest being Hurricane Rita.
