Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N between 55W and 64W .SYNOPSIS...The pressure gradient between high pressure centered north of the basin and lower pressure over South America will support strong winds in the south-central Caribbean through Tue night, pulsing to near-gale force at night offshore Colombia. Southeast to south winds in the northwestern Caribbean will increase to fresh to strong tonight through Tue as a strong cold front traverses the Gulf of Mexico. The front will weaken significantly as it reaches the Yucatan Channel Tue night, and winds in the NW Caribbean will diminish Wed and Wed night as high pressure shifts eastward across the central Gulf of Mexico. In the central Caribbean, winds will diminish to mainly fresh speeds by midweek. Southeasterly winds begin to increase over the western Caribbean Thu, reaching fresh to strong speeds Fri and Fri night, then weaken Sat and Sat night as a cold front approaches the Yucatan Channel.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extends from 31N54W to 25N66W to 24N73W, and continues as a stationary front to along the north coast of Cuba. Fresh to strong winds will continue on both sides of the front north of 28N and east of 73W as it moves eastward. The front will reach from near 26N55W to 24N65W and stationary to 23N80W this evening, then become weakening stationary Tue evening from 20N55W to near 22N65W. Southeast winds will increase to strong to near gale force west of 70W tonight, then increase to gale force Tue through Tue night north of 28N and west of 70W as a strong cold front approaches from the west. The cold front will move off NE Florida early Tue evening. By Wed evening, the front will be weakening as it reaches from near 31N68W to the central Bahamas. Very rough seas will continue Wed night east of Florida and northeast of the Bahamas. A squall line containing strong to severe thunderstorms is likely to occur just prior to the frontal passage late Tue into early Wed. Seas will subside Thu and Thu night as high pressure builds over the western Atlantic. Southerly winds begin to increase east of northern and central Florida late Fri as the next frontal system approaches from the W. It is expected to reach from near 31N77W to South Florida early Sat and from near 31N70W to the central Bahamas and to western Cuba by late Sat. Fresh to strong winds and building seas are expected on either side of this front. ATLC waters from 27N to 31N W of 77W ...GALE WARNING... .TONIGHT...SE winds 20 to 30 kt.
