The name Otto has been used for three tropical cyclones in the Atlantic Ocean.
Tropical Storm Otto (2004), a weak late season tropical storm that remained far from land
Hurricane Otto (2010), brought heavy rain to parts of the Caribbean before moving out into the Atlantic Ocean
Hurricane Otto (2016), a rare late season major hurricane (the latest-forming of such on record) which made landfall in Nicaragua and caused torrential rains over Central America. Became the first storm since 1996 to cross over from the Atlantic to the Pacific.
