Upper level cyclonic wind flow, with an inverted trough, covers the western one-third of the Gulf of Mexico. Upper level anticyclonic wind flow, with a ridge, covers the rest of the Gulf of Mexico. Scattered moderate to isolated strong showers and thunderstorms are in the Gulf waters in the area of cyclonic wind flow. Showers and thunderstorms that are in the NE corner of the area, from 27N northward between 84W and 90W, are associated with T.D. GORDON, well inland over the southern United States. These showers and thunderstorms should diminish through tonight. Weak ridging will build from the Carolinas to the coast of Texas in the wake of Gordon, supporting gentle to moderate easterly winds and modest seas into early next week. The exception will be fresh winds pulsing off the west of coast of the Yucatan peninsula, mainly during the late evening, due to a daily trough that sets up over the southwest Gulf. ...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN 55W AND 64W... Upper level cyclonic wind flow covers the Caribbean Sea to the west of the line that runs from Puerto Rico to La Peninsula de la Guajira of northern Colombia.
