510 AXNT20 KNHC 162222 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0015 UTC Fri Oct 16 2026 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 1800 UTC surface analysis and satellite imagery through 2200 UTC. ...SPECIAL FEATURES... Gulf of America Gale Warning: A cold front has entered the far NW Gulf and extends from 30N93W to 26N97W. Fresh to strong N winds and building seas follow the front, forecast to reach from near Tampa Bay, Florida to the central Bay of Campeche by early Sat morning, and from the Straits of Florida and the SE Gulf to the eastern Bay of Campeche by early Sun morning. The front will be just SE of the area on Mon where it will gradually dissipate. Strong gale force winds and rough to very rough seas are expected in the wake of the front over the west-central Gulf tonight, and over the southwest Gulf by Sat morning. Frequent gusts to gale- force are forecast elsewhere NW of the front tonight into Sat morning. Looking ahead, strong high pressure will build over the lower Mississippi Valley behind the wake of the front, promoting fresh to strong NE to E winds mainly over the eastern half of the Gulf likely through Tue. Please read the latest High Seas Forecast issued by the National Hurricane Center under AWIPS/WMO headers FZNT02 KNHC/HSFAT2 or at website https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml for further details. ...MONSOON TROUGH/ITCZ... The monsoon trough enters the Atlantic near 13N17W and extends SW to 09N34W. The ITCZ extends from 05N45W to 05N54W. Scattered moderate convection is occurring from 06N to 11N between 30W-40W. ...GULF OF AMERICA... See details above about a Gulf of America Gale Warning. An upper-level trough over the south-central US and a surface trough in the western Gulf are supporting numerous showers and thunderstorms across much of the interior Gulf. Another surface trough along the Mexican coast supports scattered moderate convection offshore Veracruz. A cold front has entered the far NW Gulf and extends from 30N93W to 26N97W. Fresh to strong N winds and building seas follow the front. For the forecast, cold front is forecast to reach from near Tampa Bay, Florida to the central Bay of Campeche by early Sat morning, and from the Straits of Florida and the SE Gulf to the eastern Bay of Campeche by early Sun morning. The front will be just SE of the area on Mon where it will gradually dissipate. Strong gale force winds and rough to very rough seas are expected in the wake of the front over the west-central Gulf tonight, and over the southwest Gulf by Sat morning. Frequent gusts to gale- force are forecast elsewhere NW of the front tonight into Sat morning. Looking ahead, strong high pressure will build over the lower Mississippi Valley behind the wake of the front, promoting fresh to strong NE to E winds mainly over the eastern half of the Gulf likely through Tue. ...CARIBBEAN SEA... Upper-level diffluence over the NW Caribbean is supporting numerous moderate to strong convection W of 80W. Otherwise, the seasonal pressure gradient is leading to moderate to fresh trades through the basin, with strong easterly winds offshore Colombia and in the Gulf of Venezuela. Moderate seas prevail across much of the Caribbean, with rough seas offshore Colombia. For the forecast, as a cold front moves across the Western Atlantic and the Gulf of America, the pressure gradient will relax across the basin. Under this weather pattern, expect moderate to fresh winds offshore Colombia and in the Gulf of Venezuela with moderate to locally rough seas near the coast of Colombia tonight and Sat. Moderate or weaker winds and slight to moderate seas are forecast elsewhere. An area of showers and thunderstorms associated with a surface trough will continue to affect the NW Caribbean tonight. Moisture associated with this feature will merge with the cold front moving across the Gulf this weekend. The front will likely reach western Cuba and the Yucatan Channel by Tue. ...ATLANTIC OCEAN... A cold front extends from 31N45W to 28N50W, and then is stationary to 25N70W. Moderate to fresh SW winds, 7-9 ft combined seas in NW swell, and scattered showers and thunderstorms are active along the front east of 51W. To the south, a surface trough is analyzed along 53W from 12N to 19N, with an upper level low nearby supporting scattered showers and isolated thunderstorms along 50W from 14N to 19N. To the northeast, a surface trough is analyzed from 27N37W to 20N39W with a 1011 mb low along the trough near 23N38W. These features are also driving fresh to strong SE winds E of the trough to about 30W and N of 20N. Diffluence aloft and east of this trough supports numerous showers and thunderstorms from 17N to 27N between 25W and 35W. Elsewhere across the Atlantic, moderate or weaker winds and seas are evident across the basin. For the forecast west of 55W, high pressure off the Carolinas will shift eastward ahead of a strong cold front that will move off the coast of northeast Florida by early Sat morning. The front will reach from 31N72W to the Straits of Florida by early Sun morning, and from near 31N71W to western Cuba by early Mon morning, then stall and dissipate through early next week. Strong to near-gale force winds and rough to very rough seas will follow the front affecting mainly the waters W of 65W through Tue. $$ Adams/Landsea
