Hurricane forecasters were tracking three disturbances in the Atlantic Ocean Sunday afternoon, one of which is expected to briefly become the season's fourth named storm as it moves away from the U.S. UPDATE: Tropical Storm Dexter forms in Atlantic as forecasters track two other disturbances

The National Hurricane Center (NHC) predicts that Dexter will not strengthen significantly due to high wind shear and dry air. The storm is expected to become a post-tropical cyclone by Wednesday (August 6) as it moves further into the Atlantic. WESH reports that Dexter poses no threat to Florida or any other land areas.

A low pressure system developed into Tropical Storm Dexter over the western Atlantic late on Aug. 3, forecasters said.
