High pressure over the southeastern United States will support moderate to fresh northeast to east winds into the weekend. Potential Tropical Cyclone Nine currently over the central Bahamas will track northwestward off the east coast of Florida through early next week. The gradient between the cyclone and the high pressure will allow for fresh winds over the NE Gulf today through Sat along with building seas. Scattered showers and thunderstorms are expected across the eastern Gulf through Sun. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... High pressure north of the area will maintain moderate trades, that will at times pulse to fresh to strong in the south central Caribbean. A tropical wave, with axis along 81W will move across Central America on Sat. Another tropical wave, with axis along 53W will move across the tropical N Atlantic through late tonight, and across the eastern Caribbean on Sat. A third and stronger tropical wave will approach the tropical N Atlantic and eastern Caribbean over the weekend into early next week, expected to bring widespread showers and thunderstorms, gusty winds and building seas. A tropical wave located midway between the Cabo Verde Islands and the Lesser Antilles is producing a large but disorganized area of cloudiness and showers. Conditions are expected to become more conducive for development in a couple days, and a tropical depression could form early next week while the system moves westward across the tropical Atlantic. Please, see the latest Tropical Weather Outlook issued by the National Hurricane Center for additional information. ...SW N ATLANTIC INCLUDING THE BAHAMAS...
