Based on 0000 UTC surface analysis and satellite imagery through 0500 UTC. ...TROPICAL WAVES... An eastern Atlantic tropical wave is east of the Cabo Verde Islands near 20W from 23N southward, and moving west at 5 to 10 kt. Scattered moderate convection is seen from 11N to 13N between 18W and 22W. A central Atlantic tropical wave is near 36W from 20N southward, and moving west at 10 to 15 kt. Scattered moderate convection is present from 07N to 09N between 30W and 37W. A western Atlantic tropical wave is near 53W from 20N southward to near the Suriname-French Guiana border, and moving west around 10 kt. Scattered moderate convection is occurring from 07N to 12N between 50W and 57W. ...MONSOON TROUGH/ITCZ... A monsoon trough enters the Atlantic near the Western Sahara- Mauritania border across the Cabo Verde Islands to 08N37W. Scattered showers are noted south of the trough near the coast of Guinea-Bissau, Guinea and Sierra Leone. An ITCZ continues from 08N37W to 09N51W, then resumes from 09N55W to the coast of northeastern Venezuela near 09N61W. Scattered moderate convection is seen up to 80 nm along either side of the ITCZ fragments. The eastern end of the East Pacific monsoon trough is triggering scattered showers and isolated thunderstorms over the Caribbean waters near Panama and northwestern Colombia. ...GULF OF MEXICO... An upper-level trough is triggering scattered showers and thunderstorms over the central and southeastern Gulf, and near the coast of central Florida. A broad surface ridge extends southwestward from a 1018 mb high over the northeastern Gulf to near Tampico, Mexico. It is supporting light to gentle winds and 1 to 2 ft seas for the north-central and northeastern Gulf. Moderate to locally fresh ENE to SE winds and seas of 3 to 4 ft exist along the western Gulf and eastern Bay of Campeche. Gentle to moderate ENE to SE winds and seas at 2 to 3 ft prevail for the rest of Gulf. For the forecast, the surface ridging will support gentle to moderate winds and slight seas across most of the Gulf into early next week. Fresh E winds will briefly pulse west of the Yucatan Peninsula during the evening hours through mid week due to a diurnal trough. ...CARIBBEAN SEA... An upper-level low near the Island of Youth is causing isolated thunderstorms near the southern coast of Cuba and east coast of the Yucatan Peninsula. Convergent trades are producing similar conditions over the southeastern basin near the ABC Islands. Refer to the Monsoon Trough/ITCZ section for additional weather in the basin. Fresh to strong ENE trades and 6 to 8 ft seas are evident at the south-central basin, north of Colombia. Gentle ENE to E trades and seas at 3 to 4 ft are noted for the northwestern basin. Moderate to locally fresh easterly trades and seas of 5 to 7 ft prevail for the remainder of the basin. For the forecast, winds will pulse to fresh to strong over the central Caribbean, while freshen over the eastern Caribbean through Sun. Gentle to moderate winds and slight seas will persist over the northwestern Caribbean into early next week. ...ATLANTIC OCEAN... A broad upper-level low north of Pareto Rico near 26N64W is generating isolated thunderstorms from north of 25N between 62W and 70W. Refer to the Monsoon Trough/ITCZ and Tropical Waves sections for additional weather in the Atlantic Basin. The Bermuda High is sustaining light to gentle winds and seas of 2 to 4 ft north of 23N between 50W and the George-Florida coast. Gentle to moderate NE trades and 4 to 6 ft seas are found farther south from 10N to 23N between 35W and the Lesser Antilles, and farther east north of 18N between 25W and 50W. Near the Canary Islands, Moderate to fresh NNE trades are present north of 23N between the northwest African coast and 25W. Gentle to moderate monsoonal and southeasterly winds with 4 to 6 ft prevail for the rest of the Atlantic Basin. For the forecast west of 55W, a ridge related to the Bermuda High along 30N will lift north of the area through Fri. Gentle to moderate E to SE winds and slight to moderate seas will remain over most of the area through early next week. Fresh to occasionally strong winds will pulse north of Hispaniola and in the approaches to the Windward Passage during the late afternoons and overnight hours through late Mon. $$ Chan
