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

.SYNOPSIS...A frontal boundary will move into the far northeast
Caribbean and stall through Sat, then dissipate. High pressure
will build in the wake of the front across the western Atlantic
into Sat. Large, long-period northerly swell will also accompany
the front, impacting the Atlantic passages into the northeast
Caribbean Sat, the Atlantic waters east off the Leeward Islands
starting Sat night, and the waters east of the Windward Islands
by early Sun before subsiding into Mon. The pattern will also
support moderate to fresh trade winds over the eastern and
south- central Caribbean, with stronger winds pulsing off
Colombia through early next week.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A mostly stationary front extending from 25N55W to
northeast Hispaniola will move little today, ahead of a
reinforcing front from 31N55W to central Cuba. Winds to gale
force are both ahead and behind the reinforcing front N of 28N,
with rough to very rough seas. These winds and seas will move
southeast of Bermuda today. The fronts will merge late today and
shift east of the area by early Sat. Farther west, expect SW
gales and rough seas off northwest Florida late tonight into
early Sat, ahead of another cold front that will move off the
coast Sat. This front will shift across the forecast waters and
exit east of the area through Mon. As with the earlier front,
gale force winds and rough seas are possible over the northern
waters in the vicinity of the front through Sun. Winds and seas
will diminish as high pressure builds over the basin Sun into
Mon.
