Atlanta, Ga - Tropical activity is nonexistent across the Atlantic Basin thanks to the presence of the Saharan Air Layer that continues to flow off the west coast of Africa. This layer of Saharan air is based roughly between 5,000 and 15,000 feet above sea level and moves from east to west across the Atlantic Basin. It is very hot, dry and dusty and acts as a cap in the atmosphere that prevents thunderstorms from forming. Without the development of thunderstorms it's impossible for tropical development to take place.
Eventually this pattern will break down, but it may take a few weeks for that to happen. Eventually once that occurs we will likely see an increase in tropical development heading into what is historically the peak of hurricane season.
