Storm names[]
The following names were used to name tropical cyclones in the South Atlantic during 2017-18. Unused names are marked in gray.
Because of the incredible damage hurricanes 'Isabela' and 'Luciana' did to Brazil both storm names will be retired and will never be used for another South Atlantic tropical cyclone ever again. Their replacements are Isaura and Luana, for use in 2022-23, as the basin name list rotates every 5 years.
