Only three tropical cyclones are known to have formed in the
Southern Atlantic Ocean, the most recent of which was Tropical
Storm Anita in 2010.
On Sunday, Brazilian meteorologists began tracking a new
tropical storm, Iba, that has formed off the country’s southeast
According to the Brazilian Navy Hydrographic Center, the storm
formed maximum winds of 40mph and a central pressure 1008
estimates suggest it has intensified to 50mph, but it is not
expected to directly threaten land.
Although Iba is not all that far from the Brazilian coast,
atmospheric steering currents will pick up the storm and carry it
to the south and then southwest by Tuesday or Wednesday. Once over
the Southern Atlantic Ocean, cooler waters and unfavorable winds
should act to dissipate the storm. Over the next day or so, it
should come nearest to Brazilian towns Caravelas and Vitoria.
