Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N between 55W and 64W .SYNOPSIS...High pressure northeast of the region will maintain fresh to strong trade winds and building seas from the tropical north Atlantic west of 55W to the south central Caribbean through Sat. A strong cold front will move through the Yucatan Channel late Wed, then across the far northwest Caribbean before stalling and weakening from central Cuba to central Honduras by late Thu. Fresh to strong northerly winds will accompany the front. Looking ahead, another front may move across the southern Gulf of Mexico and approach the northwest Caribbean by late Sat, but the precise timing remains uncertain at this time.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...High pressure over the area will continue to slide eastward through Wed in response to a strong cold front currently over the southeastern U.S. This cold front will move off the southeastern U.S. coast late tonight, reach from near 31N70W to western Cuba on Wed night, and then from 27N65W across the central Bahamas to central Cuba on Thu night. Strong north to northeast winds and building seas are expected across much of the forecast waters following frontal passage. The front will gradually stall over the central waters Fri and Fri night. Looking ahead, fresh to strong easterly winds may persist Sat across much of the western part of the area and NW Bahamas to northeast Florida as low pressure develops in the Gulf of Mexico and tracks in a general east to northeast direction. Exact timing and location of this low remains uncertain. ATLC waters from 27N to 31N W of 77W ...GALE CONDITIONS POSSIBLE... .TONIGHT...SW winds 10 to 20 kt.
