Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...Strong SW winds are ahead of and following a cold front moving off the northeast coast of Florida currently reaching from 31N79W to Cape Canaveral. The winds will diminish this afternoon as the front moves farther east, eventually stalling from Bermuda to the central Bahamas to central Cuba by late Wed. Low pressure will form along the front near the northern Bahamas tonight into Wed. This pattern will support strong to near- gale force NE winds with building seas north of 29N between 70W and 80W late late tonight into Wed night, with winds reaching gale force Wed morning into afternoon along with rough to very rough seas. Conditions will improve through Thu as the low pressure dissipates. Looking ahead, another weaker front will move off the coast of Florida Fri night, followed by moderate to fresh winds. Farther west, large N swell impacting waters east of 60W will continue southward into the tropical Atlantic through tonight. ATLC waters from 27N to 31N W of 77W .TODAY...W winds 10 to 20 kt.
