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

.SYNOPSIS...A late season cold front passing over the Bahamas is
reducing the N-S pressure gradient and forcing only moderate to
locally fresh trades over the Caribbean through tonight. As high
pressure builds in behind the front, the trades will strengthen
to fresh to locally strong just north of Colombia, through the
Windward Passage, and in the lee of Cuba Wed and Thu. Looking
ahead, further building of the high on Fri and Sat will also
force fresh to strong trades in the Gulf of Honduras and just
south of Hispaniola.
