Synopsis for Caribbean Sea and Tropical N ATLC from 07N to 19N between 55W and 64W .SYNOPSIS...Fresh to strong trade winds will continue over the S central Caribbean Sea through Wednesday night and increase to near gale or gale force along the immediate coast of Colombia each night through Thu night. Moderate to locally fresh trade winds will prevail elsewhere. A strong cold front will enter the NW Caribbean Sea later this morning, then move SE and extend from central Cuba to the Gulf of Honduras tonight. The front will weaken but still extend from SE Cuba to the NW and N central coast of Honduras on Monday night, and then start to weaken and drift N from Cuba westward from Tuesday morning until Tuesday night. Fresh to strong NW to N winds and seas to 8 ft are expected W of the front, from Sunday morning until Monday night. Strong high pres building over the western Atlc will increase the pressure gradient over the basin Tue through Thu. As a result, strong winds will affect almost all of the eastern and central Caribbean during this time frame. NW Caribbean W of 85W .TODAY...NW winds 15 to 25 kt.
