Synopsis for Caribbean Sea and Tropical N Atlantic from

.SYNOPSIS...Expect fresh to strong E to SE winds to persist
through Tue over the northwest Caribbean, between high pressure
well north of the Bahamas and a trough extending from Haiti to
Jamaica to northeast Nicaragua. A cold frontal system entering
the Gulf of Mexico tonight will move through the Yucatan Channel
and into the NW Caribbean Thu night then dissipate. Large N
swell will reach the Atlantic Passages of the NE and E Caribbean
late Tue and persist through early Thu before subsiding. Looking
ahead, fresh to strong NE winds will develop across the Windward
Passage Fri into Sat as high pressure builds north of the region
behind the next Atlantic cold front.
