{"msg": "557\nAXNT20 KNHC 092302\nTWDAT \nTropical Weather Discussion\nNWS National Hurricane Center Miami FL\n0015 UTC Tue Nov 10 2026\nTropical Weather Discussion for North America, Central America\nGulf of America, Caribbean Sea, northern sections of South\nAmerica, and Atlantic Ocean to the African coast from the\nEquator to 31N. The following information is based on satellite\nimagery, weather observations, radar and meteorological analysis.\nBased on 1800 UTC surface analysis and satellite imagery through \n2230 UTC.\n...SPECIAL FEATURES...\nWestern Atlantic Gale Warning: A 997 mb low pressure is centered \nnear 30N44W, moving eastward near 20 kt. A warm front is north of\nthe low from 30N47W to 31.5N42W to 27N32W. Recent satellite \nscatterometer data showed a long fetch of gale force SW to S winds\noccurring in the S and SE quadrant of the low, from 23N to 31N\nbetween 40W and 47W, where buoy and altimeter data suggest seas \nof 12 to 19 ft in mixed swell. Also shown in the scatterometer\ndata north of the warm front, a broad zone of strong to gale \nforce NE to E winds extends northward to 34N between 38W and 47W,\nwhere seas are 9 to 14 ft. Across the remaining quadrants of the \nlow, strong winds and rough seas to 10 ft cover the area N of 20N\nto 34N between 35W and 55W. Scattered to numerous moderate to \nstrong convection is occurring mostly to east of this deep- \nlayered low pressure system, N of 28N between 34W and 39W. The \nlow has begun to accelerate to the east-northeast and will move  \neast of 35W by midday Tue. The broad zone of strong to gale force\nSW winds occurring with the low will shift in sync with the low \nthrough Tue, generating very rough to high seas to around 20 ft \ntonight before exiting the forecast area Tue. \nPlease read the latest High Seas Forecast issued by the National \nHurricane Center at website: \nhttps://nhc.noaa.gov/text/HSFAT2.html\n...MONSOON TROUGH/ITCZ...\nThe monsoon trough enters the Atlantic waters near 11N15W to \n09N20W. The ITCZ extends from that point to 05.5N34W to 07.5N51W\nto 06.5N57W. Scattered moderate convection is noted from 05N to\n09N between 15W and 22W, from 03N to 07N between 30W and 39W.\nScattered moderate isolated strong convection is noted from 05N to\n12.5N between 47W and 57W.\nGULF OF AMERICA...\nA surface trough extends along coastal Deep South Texas to the \nMexican offshore waters near 20N95W, and is generating scattered \nshowers and isolated thunderstorms N of 22N and W of 92W.  \nModerate to fresh E-SE winds and moderate seas in the 4 to 6 ft \nrange are N of 24N and W of 94W, while light to gentle winds and \nslight seas are elsewhere E of 90W.\nFor the forecast, broad high pressure across the area supports \ngentle to moderate winds except locally fresh in the NW Gulf. \nSlight seas dominate the NE half of the basin with moderate seas \nelsewhere. Winds will diminish to light to gentle across the basin\nby midweek. The next cold front will move into the NW Gulf on Thu\nand rapidly shift across the Gulf basin, moving SE of the area \nFri. The front will be followed by fresh to locally strong winds \nand building seas. High pressure will settle across the basin in \nthe wake of the front during the weekend with moderate to fresh \nreturn flow. \n...CARIBBEAN SEA...\nWeak high pressure has moved into the western Atlantic near\n24N69W, bringing a return to easterly trade winds to much of the\nCaribbean this afternoon. Gentle to moderate trade winds prevail \nacross the NW basin with seas of 2-4 ft. Recent scatterometer \ndata indicated moderate to fresh trades S of 15N from the SE basin\nto offshore NE Colombia. Seas are 4 to 6 ft in this area. A \nsurface trough extending from the Gulf of Honduras to the SW \nCaribbean is generating scattered moderate isolated strong \nconvection from 16N to 21N west of 81W. \nFor the forecast, the weak pressure gradient across the basin \nhas begun to tighten slightly this afternoon, bringing a return to\neasterly trade winds. By Tue morning, fresh to strong winds will\nprevail across south central portions, with  moderate to locally \nfresh winds elsewhere, except weaker near Central America. Expect\nrough seas with the fresh to strong winds and mainly slight to \nmoderate seas elsewhere. Winds will weaken over the western \nportion of the basin toward the end of the week as a cold front \napproaches from the NW. The front may enter the NW Caribbean Fri \nand gradually wash out into the weekend, with moderate to fresh \nwinds and building seas behind it.\n...ATLANTIC OCEAN...\nPlease see the Special Features section for information on a Gale\nWarning and associated conditions across the NE zones.\nA cold front extends from the central Atlantic through 31N59W to\n1015 mb low pressure near 27.5N69W then through the central Bahamas\nalong 24N. North of the front, gentle to moderate northerly winds\nprevail east of 76W, where seas are 5 to 8 ft in E swell generated\nby the gale system. Elsewhere west of 60W, winds are light to gentle\nwith seas of 5 to 7 ft in NE swell. East of 35W, a weakening cold\nfront has moved SE of the Canary Islands, with moderate to fresh \nW winds and seas of 8-12 ft behind the front to 20W and N of 28N.\nNW swell across this region is producing seas of 7 to 9 ft N of\n17N and east of 35W. Gentle to moderate or weaker winds and \nmoderate seas prevail across the remaining Atlantic.\nFor the forecast west of 55W, fresh to locally strong SW winds \nnorth of 20N and east of 58W will gradually diminish through the \nevening as parent gale force low pressure moves farther away from\nthe area. Associated rough to very rough seas in NE swell north \nof 20N and east of 60W will subside by early Tue. Meanwhile, a \ncold front extends from 31N59W through a 1015 mb low at 27.5N69W \nto the Central Bahamas. The front and low will move eastward over \nthe waters north of 25N through midweek. Another, stronger cold \nfront will enter the NW waters toward the end of the week, \nushering in fresh to strong winds and building seas on both sides \nof it. The front should reach from 31N67W to the SE Bahamas by \nearly Sat, continuing eastward while gradually weakening by the \nend of the weekend.\n", "title": "Atlantic Tropical Weather Discussion", "id": "1226161949446045699", "issued": "2026-11-09T00:15:00Z", "wmo": "AXNT20", "source": "NOAA/NWS National Hurricane Center, received via the National Weather Wire Service", "page": "https://hurricane.terrapin.com/text/1226161949446045699"}
