Tropical Storm Gilda was notable as being the first observed tropical cyclone to transition into a subtropical cyclone; several subtropical cyclones have undergone tropical cyclogenesis, but never the opposite. Since Gilda, a few other storms accomplished the feat. In 1980, a tropical depression dissipated, reformed as a subtropical depression, and later became Hurricane Georges over the open Atlantic Ocean. The next year, Tropical Storm Jose became subtropical near the end of its duration, and in 1984, Hurricane Klaus became a subtropical storm over the western Atlantic Ocean. In 2001, Tropical Storm Allison, after causing devastating flooding in Texas, became a subtropical storm over the Gulf of Mexico and moved across much of the southeastern United States. In 2011, Tropical Storm Lee transitioned into a subtropical storm while approaching Louisiana.
