High pressure ridging from the Atlc over the Gulf will support gentle to moderate winds over the basin through Thu night as a frontal boundary remains stalled just N of the Gulf. A strong cold front will move over the NW Gulf by Fri morning, then eventually stall from S Florida to the Bay of Campeche by Sat night. Strong winds and building seas are expected behind this front. NW to N winds could reach minimal gale force late Fri night through Sat night over the far western Gulf S of 26N. Scattered showers and thunderstorms are likely to precede this front. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... High pres over the central Atlc will weaken as it shifts SE during the next few days. Accordingly, light to moderate trades are expected for the next several days. A mid to upper-level trough extending from the central Atlantic to the central Caribbean will combine with a tropical wave over the eastern Caribbean to produce showers and thunderstorms, some possibly with gusty winds, over much of the NE Caribbean through Thu. NE swell over the tropical Atlantic waters will subside through Thu. High pres ridging back in from the NE will cause winds and seas E of the Windward Islands to build over the weekend. ...SW N ATLANTIC INCLUDING THE BAHAMAS... NE long period swell over the eastern waters will subside through Thu. High pressure ridging over the area will remain weak this week in response to cold fronts moving off the E coast of the United States Wed and Sat. A cold front is expected to push into the NW section of the area Sat and Sat night, then stall and weaken near the northernmost Bahama Islands Sun and Sunday night. Fresh to strong NE winds and seas building to above 8 ft will affect the waters N of 28N Sat night and Sun.
