However, thunderstorms capable of drenching rainfall could bring flash flooding and strong wind gusts to portions of Florida, with waterspouts possible along the coast, AccuWeather forecasters said.

While the tropics are expected to remain calm for rest of August, forecasters expect the hurricane season to "dramatically intensify" by September.

"I think things could get very active potentially very quickly here as soon as that dry air goes away," AccuWeather Lead Hurricane Expert Alex DaSilva said, "We could see a parade of storms." This dramatic increase in activity will start at the end of August and persist throughout September.
