759 AXNT20 KNHC 020956 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1215 UTC Sun Nov 2 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 0700 UTC. ...TROPICAL WAVES... A tropical wave has its axis along 70w/71W south of 22N, moving westward around 15 kt. Scattered moderate convection is noted from 15N to 28N between 67W and 73W, enhance somewhat by a stationary front located just to the NW-N of the tropical wave in the SW N Atlantic waters. ...MONSOON TROUGH/ITCZ... The monsoon trough enters the Atlantic near the border of Mauritania and Senegal at 16N16W and continues southwestward to near 10N23.5W. The ITCZ then is analyzed from 10N23.5W to just NE of the coast of Brazil and French Guiana at 05.5N51W. Scattered moderate convection is noted from 04N to 18N, and E of 46W. ...GULF OF AMERICA... A frontal boundary/trough extends from near S Louisiana to near Brownsville, Texas. Scattered moderate convection is noted across the NW and N-Central Gulf N of 24N and W of 89W as depicted on conventional satellite imagery. Fresh to strong NE winds are N of the boudary per earlier ASCAT scatterometer data and in-situ observations. Seas are 3-5 ft N of the boundary. Mainly gentle to moderate easterly winds and 1-3 ft seas are elsewhere in the basin and ahead of the boundary. For the forecast, the front will shift ESE today, reaching from the Florida Panhandle to Tampico, Mexico later this morning, then from near Fort Myers, Florida to the eastern Bay of Campeche early Mon, clearing the basin Mon night. Fresh to locally strong winds and moderate to locally rough will follow the front through Mon night. High pressure will then follow the front supporting a gentle to moderate anticyclonic flow by the middle of the week. ...CARIBBEAN SEA... Refer to the section above for details on a tropical wave over the central Caribbean at 70W/71W including associated active convection. A surface trough extends from near the Cayman Islands to offshore Nicaragua and Costa Rica. Scattered moderate convection is noted near the trough axis, particularly from 18N to 21.5N between 78W and 81W, and from 09N to 16.5N between 77.5W and 83.5W enhanced in the SW Caribbean due to the monsoon trough extending from the NE Pacific Ocean. Fresh to strong E-SE winds and 5-7 ft seas are noted over the Caribbean E of the wave axis, with moderate to fresh NE-E winds and 4-6 ft seas from 11N to 18N between the wave and 79W, and mainly gentle to moderate winds and 2-4 ft seas across the remainder of the basin. For the forecast, the surface trough will linger through this morning with moderate to locally fresh N to NE winds just W of it. Fresh to locally strong E to SE winds are in the wake of a tropical wave, currently moving across the eastern Caribbean, with axis near 71W. These winds will expand to the central Caribbean today as the wave continues to move westward through Mon. Moderate to locally rough seas will be associated with the wave. A cold front will to move across the NW Caribbean by Mon night into early Tue while the above mentioned tropical wave is expected to merge with the frontal boundary or dissipate. ...ATLANTIC OCEAN... A stationary front extends from 29N55W to the Central Bahamas. Scattered showers and isolated thunderstorms are possible near the boundary as described with the tropical wave discussed above. Moderate to locally fresh NE winds are just W of the boundary, with moderate to fresh SE winds S of 24N and E of the front to 60W. A weak ridge is to the ESE from 31N41W to 27N63W with gentle anticyclonic winds underneath it. A 1012 mb low pressure area is noted near 31N28.5W with a cold front arcing around it from 31N26W to 19N38W. Scattered moderate convection is present within 510 nm in the SE semicircle of the low as depicted on METEOSAT-10 infrared satellite imagery. Fresh to strong N winds are N of 29N and W of the low to 33W, with fresh to strong S-SW winds N of 23N within 180-240 nm ahead of the front. Associated 8-14 ft seas are found N of 23N between 20W and 45W. Moderate to fresh trades are S of 23N/24N and W of 48W with 6-8 ft seas. Mainly moderate or weaker winds and 5-7 ft seas prevail elsewhere, except lower 3-5 ft seas N of 26N and W of 70W. For the forecast west of 55W, the stationary front will dissipate to a remnant trough and shift westward through Mon. Rough seas N of 29N and E of 60W will shift E through early Mon. A cold front is forecast to impact the region early next week, slowly shifting SE and reaching from near Bermuda to the SE Bahamas Tue. Fresh to strong winds will follow the front through late Tue, while rough seas persist in its wake through midweek. The front will then weaken and wash out through midweek with improving marine conditions. $$ Lewitsky
