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

.SYNOPSIS...Locally strong winds and rough seas are expected in
the south-central Caribbean through Tue. Rough seas in east
swell over the tropical Atlantic waters east of the Lesser
Antilles will gradually subside through tonight. A strong cold
front moving through the Yucatan Channel this afternoon will
stall Tue from eastern Cuba to eastern Honduras, then weaken and
gradually dissipate for the latter half of the week. Behind the
front, strong to near gale force N winds and rough to very rough
seas can be expected. Aside from the strong winds and seas, the
front will support the development of heavy rainfall and
thunderstorms over Central America and adjacent waters through
at least Thu.
