Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A 988 mb low is centered north of the area near 38N62W, and a cold front trails to the southwest from 31N59W to 23N65W where it stalls and continues to the Windward Passage. Fresh to strong NW to SW winds associated with this front north of 27N between 55W and 70W, will diminish tonight into Fri. Rough seas associated with this low will continue north of 27N and east of 72W before slowly diminishing through Sat. Elsewhere, moderate to fresh trades will occur east of the Lesser Antilles through Fri, becoming gentle to moderate this weekend. A weak front will move through the waters off the coast of Florida and the Bahamas tonight into Fri, supporting moderate NE winds through this weekend. Looking ahead, increasing NE winds and building swell is expected west of 55W and north of the Greater Antilles early next week as a strong front moves through the waters off the east coast of Florida.
