The monsoon trough passes through the coastal sections of Liberia near 07N11W near the border with Sierra Leone, to 05N14W, and to 04N16W. The ITCZ continues from 04N16W, to 03N18W, 01N20W, 01N23W, and to 01N32W. Precipitation: scattered moderate to strong is from 01N southward between 43W and 49W, to the coast of Brazil. Isolated moderate to locally strong is elsewhere from 05N southward from French Guiana eastward. GULF OF MEXICO... Broad surface anticyclonic wind flow spans the Gulf of Mexico. A surface ridge extends from an Atlantic Ocean 1020 mb high pressure center that is near 29N72W, to central Florida, into the east central Gulf of Mexico, into the central sections of the Gulf of Mexico, and to the coast of Mexico near 21N97W. Broad upper level anticyclonic wind flow covers the Gulf of Mexico. The sky conditions range from fair skies to broken ceilings, and some visibilities range from 2 miles to 3 miles. These are some observations for the offshore oil platforms, that are in the north central sections and northwestern sections of the Gulf of Mexico. A surface ridge will remain in the northern Gulf of Mexico through the weekend. A cold front will reach the NW Gulf of Mexico on Saturday evening. The cold front will stall in the NW and N Gulf from Sunday into Monday. Fresh SE winds are expected in advance of this front. A second and stronger cold front will enter the Gulf of Mexico on Tuesday. CARIBBEAN SEA... An upper level trough passes across Hispaniola, into the central Caribbean Sea, and curving to Nicaragua. Comparatively drier air in subsidence is apparent in water vapor imagery. Precipitation: Rainshowers are possible, in broken low level clouds, mostly from 84W eastward. The current 1020 mb Atlantic Ocean high pressure center, that is near 29N72W, will maintain fresh to strong trade winds in the south central Caribbean Sea. Gale-force winds will pulse along the coast of Colombia each night through Monday night. Fresh to strong winds also will pulse each night in the Gulf of Honduras. ATLANTIC OCEAN... An upper level trough passes through 32N53W to 24N56W to 15N56W. The trough is supporting the cold front that passes through 32N52W to 25N60W, to 22N65W, and to the eastern part of the Dominican Republic near 18.5N69W. Another part of a separate upper level trough cuts across Hispaniola, and it continues into the central Caribbean Sea. Precipitation: isolated moderate to locally strong is within 120 nm to 180 nm on either side of the line that runs from 14N57W to 23N55W to 29N51W, beyond 32N51W. A 1020 mb high pressure center is near 29N72W. Surface anticyclonic wind flow covers the Atlantic Ocean from 20N northward from the 32N52W-to-Dominican Republic cold front westward. A 1024 mb high pressure center is near 31N39W. Surface anticyclonic wind flow covers the Atlantic Ocean from 20N northward from 50W eastward. An upper level cyclonic circulation center is near 30N19W. The upper level cyclonic center is moving across the northernmost parts of the Canary Islands, and in the direction of the southern coast of Morocco. Upper level cyclonic wind flow covers the Atlantic Ocean from 24N northward from 23W eastward. Precipitation: rainshowers are possible from 21N northward from 30W eastward. The current cold front will move eastward, and dissipate by Saturday morning. High pressure is building across the northern waters in the wake of the front, and will remain there through Sunday. A second cold front will move off the SE U.S.A. coast early on Monday. Strong SW winds are expected N of 25N, from Tuesday night into Wednesday, in advance of the next cold front. Strong NW winds are expected behind the front, with the sea heights ranging from 8 feet to 11 feet. $$ MT
