Seas given as significant wave height, which is the average height of the highest 1/3 of the waves. Individual waves may be more than twice the significant wave height. AMZ001-202030- Synopsis for Caribbean Sea, and Tropical N Atlantic from 07N to 19N W of 55W 429 AM EDT Thu Aug 20 2026 .SYNOPSIS...High pressure north of the Caribbean will force fresh to locally near gale-force trades, along with rough seas, across the south-central Caribbean through much of the forecast period. Moderate to fresh trades and moderate seas will prevail over the north-central and eastern Caribbean through the weekend and into early next week, perhaps increase in coverage over the tropical Atlantic and eastern Caribbean starting Sun night as a tropical wave moves across those waters. Elsewhere, moderate or lighter winds and slight to moderate seas are expected. $$ AMZ040-202030- Caribbean N of 18N W of 85W including Yucatan Basin- 429 AM EDT Thu Aug 20 2026 .TODAY...E winds 10 to 15 kt.
