Disorganized cloudiness and showers over the NE Gulf of Mexico are associated with a weak surface trough. Some of this activity may contain gusty winds causing rough seas. Moderate to fresh southwest winds are expected over the NE Gulf ahead of the trough through Sun evening. Fresh to strong winds will pulse over the western Yucatan Peninsula adjacent waters through Mon. The northern portion of a tropical wave will move from the western Caribbean Sea to the far-south central Gulf on Wed accompanied by ample deep moisture. Otherwise, high pressure will build westward across the area through Wed night. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... A tropical wave with axis near 83W will move across the rest of the western Caribbean through this evening. The passage of the wave along with high pressure north of the area will continue to support fresh to strong winds over the southwest Caribbean through tonight, and over the NW Caribbean through Sun. A recent scatterometer pass confirmed the presence of fresh to strong winds over the NW Caribbean. Fresh to strong winds will resume over the south- central Caribbean on Sun evening being supported by the passage of a new tropical wave currently located across the Lesser Antilles. ...SW N ATLANTIC INCLUDING THE BAHAMAS... The Atlantic ridge dominates the forecast area. The ridge axis is forecast to lift northward by Mon night. A trough, approaching from the E will track westward across the eastern and central forecast waters this weekend and over the western part of the area Mon before moving inland across Florida on Tue. The gradient between the high pressure and the tough will maintain mainly gentle to moderate east to southeast winds north of 22N, and moderate to fresh east winds south of 22N through most of the forecast period.
