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

.SYNOPSIS...Moderate to fresh NE winds are expected across the 
western Caribbean through Sun behind a cold front stalling from 
southeastern Cuba through the Gulf of Honduras, before the cold 
front dissipates Sun night. Elsewhere, moderate to locally fresh 
E winds will prevail over the eastern basin. High pressure will 
build over eastern Mexico early next week, and low pressure over 
northern Colombia will strengthen. The increasing pressure 
gradient between these features will lead to fresh to locally 
strong NE to E winds across much of the basin Sun night through 
at least Tue. Pulsing strong winds are expected through the 
Windward Passage, downwind of southwestern Cuba and offshore of 
Colombia, and rough seas will be possible near strong winds. 
Winds and seas will slowly diminish by mid to late week.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front extending from 31N63W to eastern Cuba 
will progress eastward through early next week, and moderate NW 
winds will occur behind the front through Sun. Farther east, 
fresh SE to S winds will occur north of 25N and east of 60W 
through Sun morning along the periphery of a 1023 mb high in the 
central Atlantic. The high will weaken and drift eastward early 
next week. South of 20N, moderate to briefly fresh trades will 
prevail into the middle of next week. Troughing will develop east
of the Bahamas Sun then drift westward toward the east coast of 
Florida by late Mon, while low pressure develops off the coast of
NE Florida. Strengthening high pressure in the central United 
States will drift eastward, and the tightening pressure gradient 
between these features will result in widespread fresh to strong 
NE winds and very rough seas north of 22N between 60W and 72W Mon
morning, with winds and seas developing farther west across the 
Bahamas by Mon afternoon. Winds and seas will diminish Tue night 
into early Wed.
