Southeast winds strengthen Tuesday through Wednesday in response to a tropical system that is expected to develop quickly from an area of disturbed weather in the northwestern Caribbean Sea and then move northward into the eastern Gulf of Mexico. There is still uncertainty in the scale, intensity and track of the tropical system as it develops. All of those factors will influence the local coastal water conditions. At the moment, Small Craft Advisory conditions are expected to develop by Wednesday night with gales possible Thursday. Conditions are expected to improve Friday and through the weekend as the tropical system rapidly tracks northward. .GULF STREAM...
