southern Bahamas and through the Windward Passage through Sat

Farther north, moderate to fresh W to SW winds will occur
offshore of northern Florida by Sat morning, with winds expanding
farther east into the central Atlantic through Sun morning,
ahead of a cold front pushing off the east coast of the United

Florida Peninsula and into the northwestern waters this weekend
into early next week, with moderate to fresh N to NE winds and
building seas expected in the wake of the front. Looking ahead,
widespread moderate to fresh trade winds will occur over much of
the western Atlantic by midweek as high pressure builds off the
coast of the eastern U.S.
