The frequency of tropical cyclone formation has definitely increased in the Atlantic Ocean basin. A tropical wave that the National Hurricane Center (NHC) had been monitoring for development since it left the African coast almost two weeks ago was upgraded to Tropical Depression Nine (TD09L) on August 28, 2016. The low pressure became a little better organized after moving into the Florida Strait and that led to the upgrade.
Tropical Depression Six (TD06L) formed in the Eastern Atlantic Ocean southwest of the Cape Verde Islands late Tuesday evening. TD06L has become better organized today. The National Hurricane Center (NHC) predicts that the tropical depression will intensify and become tropical storm Fiona later today. The tropical storm is predicted to become slightly more powerful while moving toward the northwest over the open waters of the central Atlantic.
