782 AXNT20 KNHC 071031 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1215 UTC Sun Sep 7 2025 Tropical Weather Discussion for North America, Central America Gulf of America, Caribbean Sea, northern sections of South America, and Atlantic Ocean to the African coast from the Equator to 31N. The following information is based on satellite imagery, weather observations, radar and meteorological analysis. Based on 0600 UTC surface analysis and satellite imagery through 0930 UTC. ...TROPICAL WAVES... A central Atlantic tropical wave is near 44W from 17N southward, and moving west at 10 to 15 kt. Scattered moderate convection is noted from 11N to 15N between 39W and 46W. A western Caribbean tropical wave is near 78W from eastern Cuba to around 10N, moving W at 15 to 20 kt. Scattered moderate convection is noted from Jamaica southward into Colombia, from about 75W to 81W. ...MONSOON TROUGH/ITCZ... A monsoon trough enters the Atlantic along the coast of Mauritian near 19N16W and curves southwest to 10N30W, then continues westward to 09N49W. An ITCZ continues from 09N49W to 10N59W. Scattered moderate convection is noted from 05N to 08N between 18W and 34W and from 09N to 12N between 49W and 52W. ...GULF OF AMERICA... A weak and slow moving cold front extends from near Apalachicola, Florida to near Corpus Christi, Texas. Scattered moderate convection is noted ahead of this front within about 90 nm of the western Louisiana and upper Texas coasts. To the southeast, a surface trough stretches from just north of Tampa Bay to a 1012 mb low near 27N85W to 26N92W. Scattered moderate convection is occurring between the low and the southwest coast of Florida. Winds across the basin are mainly light to gentle, with seas of 2 ft or less, except for 2 to 3 ft in the Bay of Campeche, where winds earlier in the night were stronger. For the forecast, a cold front will move into the northern Gulf today, then stall and replace the aforementioned trough through early week. North of the stalled front, some showers and thunderstorms as well as moderate to locally fresh NE winds can be expected. Otherwise, gentle winds and slight seas will prevail. ...CARIBBEAN SEA... Refer to the Tropical Waves section for information on convection in the western basin. Moderate to locally fresh E winds and seas of 4 to 6 ft are noted in the south-central basin. Gentle to moderate trades and seas of 3 to 5 ft dominate elsewhere, except for waters N of 20N and S of 11N, where winds are light to gentle are seas are 3 ft or less. For the forecast, a relatively weak pressure gradient between the Atlantic ridge and Colombian low this week will support moderate to locally fresh trade winds across the central Caribbean, with gentle winds elsewhere. Slight to moderate seas will also prevail. A tropical wave is likely to move into the eastern Caribbean Tue into Wed, bringing some showers and thunderstorms to the waters. ...ATLANTIC OCEAN... Converging low-level winds and a mid to upper level trough offshore Florida are leading to scattered moderate convection N of the Bahamas and W of 76W. To the southeast, another trough is leading to scattered moderate to isolated strong convection from 22N to 28N between 66W and 72W. The remaining convection in the basin is being caused by a tropical wave or the monsoon trough and ITCZ, and is described in the above sections. East of 70W, widespread moderate to locally fresh E winds dominate as the basin remains south of an expansive north Atlantic high pressure. Seas are 4 to 7 ft, highest in a zone from 15N to 25N between 40W and 50W. To the west of 70W, gentle southerly winds and seas of 2 to 4 ft prevail. For the forecast west of 55W, a weak cold front will move off NE Florida tonight then stall over the far NW waters Mon into mid- week. This will keep showers and thunderstorms along with locally hazardous winds and seas in place offshore Florida and north of the Bahamas during this time. Elsewhere, the Bermuda ridge will dominate weather through the forecast period, bringing gentle to moderate winds and slight to moderate seas. $$ Konarik
