Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A weak area of low pressure over S Florida will track offshore the east-central coast of Florida Sun. This system will continue to bring scattered to numerous showers and thunderstorms, some with strong gusty winds and rough seas, over the waters west of 72W the next couple of days. Environmental conditions are expected to become conducive for tropical cyclone development of this system once it moves back over the Atlantic waters. Otherwise, gentle to moderate southeasterly winds will continue across the area. Tropical Storm Dorian will approach the southern waters, possibly as a hurricane, the middle of next week.
