A rare tropical storm formed in the South Atlantic off the southeast coast of Brazil on March 24, 2019. Iba is the first named tropical storm in the South Atlantic since 2010. Only one known hurricane has ever been recorded in the South Atlantic. Hurricane Catarina made landfall over the state of Santa Catarina, Brazil, as a Category 1 storm on March 27, 2004. The lack of tropical cyclones in the region is generally attributed to cool sea surface temperatures and strong vertical wind shear according to the National Hurricane Center.
