Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extends from 31N66W to 22N70W to near the Windward Passage. Fresh to locally strong winds behind the front will diminish by tonight, while large seas north and northeast of the Bahamas will gradually subside through Tue. Another cold front will develop and cross the northern waters late Tue into Wed, resulting in fresh to strong W to NW winds and building seas. High pressure will build across the northern waters Thu through Fri. Elsewhere, a broad area of low pressure near 19N56W is expected to undergo gradual development during the next couple of days, potentially becoming a tropical or subtropical cyclone as it tracks northwestward across the SW N Atlantic before merging with the cold front.
