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

.SYNOPSIS...Fresh to strong trade winds are expected to pulse
across the central and west-central Caribbean through the middle
of next week as a strong pressure gradient prevails between high
pressure to the north and low pressure in the south-central
Caribbean. Rough seas in E swell are likely in this region.
Fresh to strong E to SE winds will also occur each night and
morning in the Gulf of Honduras, and these winds will expand
through much of the northwestern Caribbean early next week after
the passage of a tropical wave. Elsewhere, locally rough seas in
E swell will occur east of the Lesser Antilles and through the
passages into the eastern Caribbean into Sun. Otherwise, mainly
moderate winds and seas are expected across the rest of the
basin.
