Scientists once thought tropical cyclones were impossible in the South Atlantic. Another one just formed.

Did you know there’s a tropical storm right now in the Atlantic? It’s true. But it’s a bit farther south than you’re probably accustomed to.

A rare tropical depression formed off the South American coast Saturday, according to the Brazilian Navy Hydrographic Center. On Sunday, the system became a tropical storm. It was named Iba, marking the first time the agency has drawn upon its list of tropical cyclone names for a storm of purely tropical pedigree. The previous six storms that were named were “subtropical” cyclones, meaning they shared a mix of tropical and non-tropical characteristics. The list of storm names became operational in 2011.
