Winds over the most of the central Caribbean will then diminish to fresh, although strong winds will continue to pulse nightly near the coast of Colombia through the week. A cold front extends from the western tip of Cuba to Tulum, Mexico with moderate N winds north of it, over the Yucatan Channel. The front should dissipate late this afternoon as it drifts SE. SE winds will increase to fresh to strong from the Gulf of Honduras to the Yucatan Channel Thu night and early Fri as the next cold front traverses the Gulf of Mexico.
