Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...Showers and thunderstorms associated with a well- defined low pressure area centered about 80 miles east-southeast of Brunswick, Georgia, continue to lack the necessary organization for the low to be considered a tropical cyclone. However, only a small increase in the organization of the showers and thunderstorms could result in the formation of a short-lived tropical depression before it reaches the coast of northeastern Florida or Georgia tonight. Regardless of development, fresh to near gale-force SE winds and rough seas to 9 ft will prevail across the waters N of 30N and W of 78W through today. Afterward, high pressure will build in the wake of the low, supporting gentle to moderate winds through Tue night. Otherwise, moderate to fresh E winds are expected for Hispaniola adjacent waters, the approaches to the Windward Passage and the Great Bahama Bank today through Sat.
