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

.SYNOPSIS...High pressure north of the area will support
moderate to fresh trade winds over the south-central and SE
Caribbean through the weekend, with some increasing winds
possible early next week. Meanwhile, expect pulses of fresh to
locally strong E winds at night across the Gulf of Honduras into
the start of next week due to the pressure gradient between the
high pressure and lower pressure over the western Gulf. Gentle
to moderate winds and moderate seas will persist elsewhere.
