An Atlantic Ocean tropical wave is along 40W from 18N southward, moving W 10 to 15 knots. Scattered moderate convection is W of the wave from 05N-13N between 40W-43W. ...MONSOON TROUGH/ITCZ... The monsoon trough passes through the coastal sections of Guinea near 10N13W to 08N28W. Isolated moderate convection is south of the monsoon trough from 05N-07N between 14W-24W. GULF OF MEXICO... A cold front extends southward from now Post-Tropical Cyclone Beta from 30N94W to 26N95W. A stationary front continues to drape across the central and eastern Gulf from the southeast Louisiana coast near 29N90W to the NW coast of Cuba near 23N84W. Scattered moderate convection is in the eastern Gulf from 22N-30N between 84W-89W. Moderate to fresh winds are seen across the Gulf with light winds in the Bay of Campeche. Seas are 3-6 ft with up to 7 ft in the north-central Gulf. A stationary front extending from SE Louisiana to western Cuba will gradually dissipate. Remnants of the front, as a surface trough, will lift northward across the eastern Gulf over the next couple of days. A weak low may develop along the trough axis. CARIBBEAN SEA... A weakening stationary front is giving way to scattered moderate convection across Cuba into the Mona Passage, N of 18N between 67W-83W. The monsoon trough extends across the SW Caribbean from the coast of Colombia near 11N75W to the coast of Costa Rica near 10N83W. Scattered moderate convection is noted S of 14N between 74W-83W. Moderate to fresh trades prevail across most of the basin with light winds in the western Caribbean. Seas 2-4 ft. Northerly swell previously generated by Hurricane Teddy and an early season cold front in the western Atlantic has arrived in Atlantic passages and will continue into Thu night. Mainly gentle to moderate trade winds will dominate the basin through the forecast period, with the exception of moderate to fresh winds near the coast of Colombia and in the Gulf of Venezuela. ATLANTIC OCEAN... A stationary front extends from 30N57W to 24N64W to the coast of Cuba near 21N76W. Scattered moderate convection is within 200 nm east of the front. A trough is analyzed in the central Atlantic from 22N48W to 16N55W. Isolated showers are along the trough. Moderate to fresh winds are on either side of the front between 42W-75W N of 24N with gentle to moderate winds south of 24N. Seas in the central Atlantic are up to 8 ft with seas 9-15 ft in the western Atlantic.
