Synopsis for Caribbean Sea and Tropical N ATLC from 07N to 19N between 55W and 64W .SYNOPSIS...A weakening stationary front extends from SE Cuba near 21N78W to 20N82.5W to the coast of Belize near 17.5N88W. The front is forecast to dissipate on Thursday. Strong high pressure, building across the waters behind the front, will tighten the pressure gradient in the Caribbean Sea. Trade winds in the central Caribbean Sea will be enhanced through early next week. The resultant strong pressure gradient will bring gale-force NE to E winds along the coast of Colombia during the nighttime hours, beginning on Thursday and expected to continue into early next week. No large long-period swell will impact the tropical N Atlantic Ocean during the next several days. NW Caribbean W of 85W .TODAY...NE winds 10 to 20 kt.
