.SYNOPSIS...A surface trough extending from the Gulf of Honduras
to NW Honduras will drift W through Monday night. Scattered to
numerous showers and thunderstorms over much of the western
Caribbean will persist the next few days. This activity is
capable of producing strong gusty winds and rough seas. A cold
front is expected to move into the NW Caribbean on Wednesday,
reach from near E central Cuba to NE Honduras Wednesday night,
weaken as it reaches from eastern Cuba to NE Honduras Thursday
and become a dissipating trough from eastern Cuba to developing
low pressure over the Gulf of Honduras on Friday.
