Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N between 55W and 64W .SYNOPSIS...A stationary front extends from Haiti to near eastern Panama. Fresh to strong N to NE winds and seas to 11 ft follow the front. High pressure will build SE across the western Atlantic through Fri. This will force the N portion of the front to drift SE across Hispaniola through early Thu while gradually dissipating. Fresh to strong N to NE winds behind the front will veer NE tonight through early Fri, with strongest winds in the lee of Cuba and through the Windward Passage. At the same time, fresh trades are expected in the south-central Caribbean, including the Gulf of Venezuela, pulsing to strong each night. High pressure will move N of the region Sat through Sun to bring a return to more typical E trade winds. NW Caribbean W of 85W .TODAY...NE winds 10 to 15 kt.
