Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A surface ridge along 27N will maintain fresh to strong trades north of Hispaniola through Sun morning. A strong cold front will move across the western Atlantic waters near 28N Fri night, extend from near 31N48W across 28N60W to 27N67W Sat morning, and then weaken as it reaches from near 29N35W to 24N55W Sun morning. Strong NW to N winds are likely on Sat across the western Atlantic waters north of 27N behind the front, with large N swell propagating southward east of 65W though Mon night. Looking ahead, another weaker cold front should arrive over the waters north and northeast of the Bahamas on Sun, causing strong breeze to near gale conditions on both sides of the front north of 28N through Mon night. NE swell producing large seas is expected behind this front. ATLC waters from 27N to 31N W of 77W .TODAY...W winds less than 10 kt. Seas 3 ft. .TONIGHT...Variable winds less than 10 kt.
