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

.SYNOPSIS...Moderate to fresh SW winds, moderate seas and
scattered thunderstorms are active south of central Cuba this
morning ahead of a trough over the northwest Caribbean.
Scattered thunderstorms are also active across the south-central
Caribbean following a tropical wave moving into the southwestern
Caribbean, and across Puerto Rico and the Virgin Islands near an
upper trough. High pressure over the central Atlantic will
support moderate to fresh trade winds across the eastern
Caribbean through mid week, but a weak pressure pattern will
maintain gentle breezes and slight seas elsewhere.
