{"msg": "218\nAXNT20 KNHC 301057\nTWDAT \nTropical Weather Discussion\nNWS National Hurricane Center Miami FL\n1215 UTC Fri Oct 30 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 0600 UTC surface analysis and satellite imagery through \n1045 UTC.\n...MONSOON TROUGH/ITCZ...\nThe monsoon trough axis reaches the Atlantic through the coast of\nGuinea Bissau near 11N16W and continues southward to 08N25W,\nwhere it transitions to the ITCZ to 07N40W, where it is broken by\na surface trough. The ITCZ then resumes at 07N45W to 08N61W. \nScattered moderate convection is within 60 nm south of the trough\nbetween 19W-21W and within 30 nm south of the trough between\n25W-31W.\n...GULF OF AMERICA...\nA tight pressure gradient between high pressure over the eastern \nUnited States, low pressure over the Bahamas and a trough over \nthe central Gulf that extends southeastward across the northern \nYucatan Peninsula is supporting moderate to fresh northeast to \neast winds across the northeast and north-central Gulf. Moderate\nseas to around 7 ft are with these winds. Moderate, or weaker \nwinds are elsewhere as noted in overnight Ascat scatterometer \ndata passes.\nFor the forecast, the moderate to fresh northeast to east winds \nover the northeast and north-central Gulf waters will be supported \nby the gradient in place into early next week. Looking ahead, \nexpect fresh southeast to south winds over much of the northwest \nGulf by Tue night between high pressure over the western Atlantic \nand a cold front that will be moving through the Southern Plains. \n...CARIBBEAN SEA...\nA frontal boundary along with a couple of troughs that are over the \nwestern Atlantic generally maintain a weak pressure gradient over \nthe Caribbean waters west of about 76W, thus leading to light to \ngentle winds and slight seas there. Moderate to fresh trades and \nmoderate seas are elsewhere. A trough analyzed from just east of \nJamaica to just inland Colombia near 09N74W is supporting an area of \nscattered showers and thunderstorms over the waters from 15N to 19N \nbetween 72W and 77W. Similar activity is seen from 09N to 14N \nbetween 78W and 80W.\nFor the forecast, moderate to fresh trades over the central and \neastern Caribbean will continue through Mon night, then diminish \nto light to gentle. The exception is in the south-central \nCaribbean and in the Gulf of Venezuela, where fresh to strong \ntrades will begin Fri night and continue into Sun morning. Light \nto gentle breezes are forecast elsewhere into early next week. \n...ATLANTIC OCEAN...\nA cold front extends from low pressure of 1012 mb near 32.5N25W, \nsouth-southwestward to a warm front near 27N28W, and it connects to \na 1013 mb low pressure near 27N30W. A cold front extends from the \nlow pressure to 25N35W and to 27N46W, then becomes a stationary \nfront to 29N55W. It transitions to a warm front to 31N60W, to a 1011 \nmb low pressure near 31N69W. A cold front extends from the low \npressure to 28N75W, then becomes a stationary front to near South \nFlorida. A trough extends from near 30N67W to 23N68W. Overnight \nAscat scatterometer data passes depicted fresh to strong northeast \nto east winds north of the frontal boundary west of about 58W. \nRecent altimeter satellite data and buoy observations show seas of 9 \nto 11 ft with these winds. Fresh to strong northeast winds are also \nnorth of the frontal boundary portion east of 58W, with seas of 9 to \n10 ft.\nIn the far eastern Atlantic, fresh northeast winds are present \nfrom 15N to 22N between the coast of Africa and 21W, and from \n14N to 18N between 21W and 25W. Seas are 5 to 7 ft with these \nwinds. Moderate to fresh trades are south of 20N west of 50W, \nand from 10N to 19N between 35W and 50W. Seas are 4 to 6 ft with \nthese trades. Light to gentle winds are elsewhere as seen in the \novernight Ascat scatterometer data passes. Seas are 3 to 4 ft with\nthe light to gentle winds, except less than 3 ft southwest of the\nBahamas.\nFor the forecast west of 55W, fresh to strong northeast to east \nwinds along with rough seas to around 11 ft will persist north of \nthe front into next week as the low pressure moves northeastward \npast Bermuda, and the reinforced cold front moves southeastward \nand stalls near, or along 24N. \n", "title": "Atlantic Tropical Weather Discussion", "id": "1223188351102255106", "issued": "2026-10-30T12:15:00Z", "wmo": "AXNT20", "source": "NOAA/NWS National Hurricane Center, received via the National Weather Wire Service", "page": "https://hurricane.terrapin.com/text/1223188351102255106"}
