Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Fresh to strong NE winds and rough seas occurring
along and to the west of a trough, located from the Windward
Passage to 25N69W, will strengthen tonight as the trough drifts
W, and high pressure behind an approaching cold front builds
into the area. The trough will move westward across the Greater
Antilles, Turks and Caicos Islands, the southeastern Bahamas, and
eastern Cuba through Mon before quickly weakening. A strong cold
front is moving southward into the northern forecast waters this
evening, and will reach 25N Sun morning, along 20N Mon morning,
then will stall and begin to weaken along 19N Mon afternoon
through Tue. Expect widespread fresh to strong NE to E winds and
rough to very rough seas in N swell north behind the front
through early Mon before diminishing early next week. N swell
will reach the NE Caribbean Mon morning and the Tropical Atlantic
waters Mon afternoon and night. Elsewhere, moderate to locally
fresh E trades and moderate to rough seas will occur east of the
Windward Islands through the forecast period.
