Seas given as significant wave height, which is the average height of the highest 1/3 of the waves. Individual waves may be more than twice the significant wave height. Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N between 55W and 64W .SYNOPSIS...A deep layered upper trough N to S across the central Caribbean will drift westward tonight through Sat then lift northward into the Atlantic Sun. A tropical wave along 67W continues to interact with this feature to produce scattered to numerous thunderstorms between 63W and 68W early this morning. The tropical wave will move slowly W through Sat and gradually merge with the upper trough along 70W. An area of low pressure is expected to form over the eastern Caribbean Sea this weekend. Environmental conditions are forecast to be conducive for gradual development, and a tropical depression could form by early next week while the disturbance moves generally westward or west-northwestward over the central Caribbean Sea.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...Scattered to numerous showers and thunderstorms persist across the Atlantic waters between 62W and 68W, supported by a deep layered upper trough along about 70W. At the surface, a trough of low pressure stretches from Hispaniola northward along 69W-70W. These features are expected to remain nearly stationary through early Sat and maintain active thunderstorms to the E. Low pressure is expected to develop along the trough to the N of 29N by Fri. Environmental conditions appear conducive for some gradual subtropical development of this system, and a subtropical depression could form during the next couple of days, as this system drifts northward. The system is then forecast to meander over the subtropical western Atlantic to the west or southwest of Bermuda Sat through Mon. Associated large NE swell will impact the northern waters W of 70W Fri night through the weekend.
