Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N W of 55W .SYNOPSIS...High pressure N of the area will support fresh to strong NE winds in the NW Caribbean and Windward Passage through this evening. Similar wind speeds are also expected in the central Caribbean, and parts of the eastern Caribbean, including the Mona Passage, through at least Mon. These winds will diminish Mon night into Tue as the high pressure shifts eastward ahead of the next cold front forecast to enter the NW Caribbean early on Tue. The front is forecast to reach from central Cuba to Belize by Tue evening, and from the Windward Passage to the Gulf of Honduras by Wed morning before dissipating Wed night. Moderate to fresh N to NE winds and moderate seas are expected behind the front.
