Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N between 55W and 64W

.SYNOPSIS...A weakening cold front from NW Haiti to near 18N88W
will move southward and dissipate early Sat, while the remainder
of the front will become stationary over the far northwest part
of the Tropical N Atlantic waters on Sat and gradually weaken
through Sun. Strong high pressure north of the area will support
fresh to strong winds across the south-central Caribbean through
Tue, with gale conditions expected near the coast of Colombia 
during the overnight hours beginning tonight and through Sun. 
Large northerly swell will propagate through the NE Caribbean 
passages and into the Tropical N Atlantic waters through the 
weekend, with the largest swell expected Sat night through Sun 
night. A second cold front is forecast to reach from western 
Cuba to the Yucatan Peninsula on Mon and from the Dominican 
Republic to the central Caribbean by late Tue. Mainly fresh 
winds will follow in behind this front.

southerly winds are expected ahead of this front north of 27N, 
while strong west to northwest winds are expected behind it. Seas
