Colombia each night and morning through the middle of next week
as low pressure prevails over the south-central Caribbean. These
winds will bring rough seas to the waters near northwest
Colombia. Otherwise, high pressure centered over the western
Atlantic will support moderate to fresh trade winds and moderate
seas over the rest of the basin through early next week.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Locally fresh northeast winds are expected over the
southern Bahamas and through the Windward Passage through Sat
morning as low pressure prevails in the south-central Caribbean.
Farther north, moderate to fresh southwest to west 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 States. The cold front is forecast to move southeastward
along the Florida Peninsula and into the northwestern waters
this weekend into early next week, with moderate to fresh north
to northeast 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.
