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

.SYNOPSIS...A cold front moving through the Gulf of Mexico will
move through the Yucatan Channel tonight, then weaken as it
moves across the northwest Caribbean Sat. The front will stall
from eastern Cuba to the Gulf of Honduras Sat night, then
dissipate through Mon. High pressure building in the wake of the
front north of the region will support expansion of fresh to
strong trade winds and building seas from off Colombia to cover
most of the south- central and southwest Caribbean from Sun
through Tue night. This pattern will also support fresh to
strong NE winds in the lee of Cuba by Tue. Trade winds across
the central Caribbean will gradually diminish through Fri as
high pressure north of the region shifts eastward. A weak cold
front will enter the NW Caribbean Fri night, then gradually
stall and dissipate from eastern Cuba to the Gulf of Honduras
Sun. High pressure will build north of the region Mon night
through Tue and strengthen winds across the entire basin, with
gale force winds possible along the Colombian coast Mon night
and and Tue night.
