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

.SYNOPSIS...A broad inverted trough from near 16N71W across
central Hispaniola and N-NE into the Atlantic is accompanied by
very active weather. The trough will shift W and into the SE
Bahamas and eastern Cuba while weakening through Sun night. 
Atlantic high pressure will build modestly across the basin
behind the trough and allow for fresh to strong winds in the
S-central Caribbean to pulse at night through the next several
days. Winds and seas in the eastern Caribbean and Tropical N
Atlc E of the trough will gradually diminish through Sun. Weak
high pressure will then prevail N of the area Mon through Wed
ahead of a strong cold front that will move across the NW
Atlantic.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A broad inverted trough accompanied by very active
weather extends from near 29N67W to central Hispaniola, and will
continue to shift W and weaken through Sun night, while reaching
the central Bahamas. Atlantic high pres is drapped across the 
waters N of the trough, and is producing fresh winds and seas to
10 ft E of the trough. Winds and seas across the region will 
gradually diminish through Sun as the high pres weakens. A 
strong cold front is expected to move offshore of the SE U.S. 
and NE Florida today through early Sun, and sink SE across NW 
portions, reaching from near Bermuda to central Florida Sun 
evening, and from 31N60W to SE Florida by Mon evening. A large 
area of strong to gale-force N to NE winds, storm-force just N 
of 31N, and significant NE swell will build into the area behind
the front, spreading across the waters N of 26N and W of 65W by 
Tue. The front may stall along 25N/26N by the middle of next 
week.
