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

.SYNOPSIS...A surface ridge building north of the area will
force moderate to fresh trades across the Caribbean and the
tropical N Atlantic through Thu morning. Locally strong trades
are expected within 90 NM of the Colombian coast, within the
Windward Passage, and south of Hispaniola. Winds should diminish
on Thu night over the Caribbean ahead of a front moving across
the Gulf of Mexico, while the trades over the tropical N
Atlantic will remain at a fresh breeze. The weakening cold front
should reach the NW Caribbean on Fri with fresh NE winds and
building seas Fri night and Sat.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A stationary surface ridge between Bermuda and the N
Bahamas will promote gentle or weaker winds north of 25N for the
next two days. As the ridge strengthens on Wed and Thu, it will 
force fresh to strong tradewinds south of 25N including the 
Windward Passage. Fresh to strong SW winds ahead of a cold front
are anticipated to occur north of the Bahamas on Wed and Thu. 
After emerging from the SE United States coast Thu night, the 
cold front should extend from Bermuda to the central Bahamas Sat
morning with moderate to fresh NW to N winds in its wake.
