A cold front from the Florida Big Bend to 21N94.5W to the central Bay of Campeche will move eastward across the entire Gulf through tonight, with reinforcing cold air supporting strong NW winds and building seas over the northeast and north central Gulf tonight through Sat. High pressure will build in the wake of the front and support generally tranquil marine conditions across the basin Sun into Mon. The high pressure will shift east of the area early next week, allowing winds and seas to increase over the northwest Gulf Mon and Tue between the high pressure and lower pressure farther west over Texas. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W...

The front will stall from eastern Cuba to the Gulf of Honduras Sat night, then dissipate through Mon. High pressure building in the wake of the front north of the region will support the expansion of fresh to strong trade winds and building seas from off Colombia to cover most of the south-central and southwest Caribbean from Sun through Wed night.
