Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N W of 55W

.SYNOPSIS...A cold front extending from eastern Cuba to northern
Nicaragua will progress southeastward through tonight to 20N77W
to 10N83W, before stalling on Sat and gradually dissipating.
Fresh to locally strong N winds will occur in the wake of the
front, with the strongest winds occurring offshore of Nicaragua
tonight through Sat morning. Rough seas of 8 to 9 ft will
continue behind the front through the Yucatan Channel this
morning. A tightening pressure gradient between developing low
pressure in the southwestern Caribbean and high pressure
building in the southeastern United States will promote fresh NE
winds in the Atlantic Passages and in the lee of Cuba on Sat,
and moderate to fresh E to NE winds and moderate seas in E swell
will develop across much of the basin Sun through early next
week.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A Gale Warning is in effect off the coast of the
southeastern United States, north of 30N and east of 76W, in the
wake of a reinforcing cold front that will quickly sweep across 
the waters N and NE of the Bahamas today through Sat night. The 
strongest winds will occur north of 30N today and tonight. Rough
to very rough seas will accompany these winds, with seas of
12 to 15 ft expected north of 28N between 77W and 65W. Long-
period N swell with this front will produce rough seas for areas 
north of 25N by Sat morning. Rough seas will shift eastward 
through this weekend, and seas greater than 8 ft will continue 
into next week for areas east of 65W. Meanwhile, another cold 
front extending from 31N68W to 28N70W to 22N77W will progress 
eastward today, with fresh to strong SW winds occurring along and
ahead of the front. Winds associated with both fronts will merge
on Sat before the system lifts to the north of the area. 
Elsewhere, moderate to fresh E winds and moderate seas will 
prevail south of 20N into next week.
