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

.SYNOPSIS...High pressure ridging extends from the central
Atlantic westward to central Florida. It will slowly shift
eastward through the weekend. The associated gradient will
support moderate to fresh trade winds over the south-central and
southeastern Caribbean through the weekend. Winds may increase
some early next week. Meanwhile, fresh to locally strong east
winds will pulse primarily at night across the Gulf of Honduras
through Sun. Looking ahead, expect fresh to strong southeast
winds over the northwestern Caribbean and south-central
Caribbean off Colombia early next week, between the high
pressure over the western Atlantic and lowering pressure across
the southwestern Gulf of Mexico and over Colombia. These winds
may pulse to near- gale over the Gulf of Honduras by Tue night.
Gentle to moderate winds and moderate seas will persist
elsewhere.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...High pressure ridging extending westward from the 
central Atlantic to central Florida will shift slowly eastward 
through Sat, ahead of a cold front that will approach from the 
northwest. Expect fresh to strong south to southwest winds ahead
of the front tonight through late Fri between the northern
Bahamas and Bermuda. The front is expected to move off the
northeast Florida coast Fri night, then weaken as it moves east
reaching from near Bermuda to the central Bahamas by late Sat
night. Winds and seas will diminish into Mon as the dissipating
front continues to drift east of the area, and high pressure
builds between the Carolinas and Bermuda in the wake of front.
Looking ahead, southeast winds will increase and seas will build
late Mon through Tue night off northeast Florida and north of
the Bahamas, as the high pressure shifts eastward ahead of the 
next weak front that is expected to move across the southeastern 
United States.
