Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A surface ridge along 25N will shift eastward through late today ahead of a cold front moving off the coast of Florida.

The resultant pressure gradient south of the strengthened ridge will support fresh winds south of 22N, mainly along the northern coast of Hispaniola through early next week. A series of weak frontal troughs will sweep eastward across the waters N of 28N through the period. ATLC waters from 27N to 31N W of 77W .THIS AFTERNOON...NW winds 10 to 15 kt.
