Subtropical Storm Ubá was the fourth tropical or subtropical cyclone to form in the South Atlantic Ocean in 2021. Ubá originated from an area of low pressure that formed off the coast of Rio de Janeiro and evolved into a subtropical cyclone on 10 December. The cyclone lingered for two days, before weakening back to a low-pressure area and dissipating on 13 December. Together with the South Atlantic Convergence Zone (SACZ), Ubá caused heavy rains in Minas Gerais, in Espírito Santo and mainly in Bahia. The storm became the deadliest South Atlantic (sub)tropical cyclone, with a death toll of 15.
