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

.SYNOPSIS...High pressure N of area will continue to support
fresh to strong NE winds in the NW Caribbean and Windward
Passage through Sun evening. Similar wind speeds are also
expected in the central Caribbean, and parts of the eastern
Caribbean, including the Mona Passage, through at least Mon.
These winds will diminish Mon night into Tue as the high
pressure shifts eastward ahead of the next cold front forecast
to enter the NW Caribbean early on Tue. Moderate to fresh N to
NE winds and moderate seas are expected behind the front
forecast to reach from central Cuba to Belize by Tue evening,
and from the Windward Passage to the Gulf of Honduras by Wed
morning before dissipating Wed night. High pressure in the wake
of the front will support moderate to locally fresh NE winds in
the NW Caribbean through Thu.
