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 fresh to strong winds offshore Colombia through the forecast period, pulsing to near-gale force at night. Winds near the coast of Colombia will reach gale force Sun night. Looking ahead, SE to S winds in the northwestern Caribbean are expected to increase early next week as a strong cold front traverses the Gulf of Mexico. Winds will diminish Wed and Wed night as high pressure shifts eastward across the central Gulf of Mexico. NW Caribbean W of 85W .TONIGHT...SE winds 10 to 20 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extends from 31N79W to 29N81W. Strong to near-gale force S to SW winds precede the front north of 28N and west of 71W. This front is forecast to reach from near 31N75W to South Florida early Sun, from near 31N58W to the central Bahamas early Mon and from near 24N55W to 22N70W early Tue. Fresh to strong winds are expected on either side of this front N of 28N as it moves eastward Sun through Mon. The eastern part of the front will continue to E of 55W as a cold front late Tue into Wed, while the rest of the front stalls and weakens through midweek. Looking ahead to Mon night through Wed, gale force southerly winds are expected to precede yet another strong cold front over the waters east of NE Florida, while strong to near gale force southerly winds are likely elsewhere N of 26N and W of 65W. The gales are likely early Tue through early Wed, N of 28N between Florida and 70W. Scattered strong to possibly severe thunderstorms may precede this front. By late Wed, this front will be weakening as it extends from near 31N69W to the central Bahamas and to western Cuba, but very rough seas will continue Wed night east of Florida and northeast of the Bahamas. These conditions will slowly subside Thu and Thu night as modest high pressure builds over the western Atlantic.
