WXTLIST WMO=AXNT20 AXNT20 KNHC 060009 2025096 0010 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0015 UTC Sun Apr 06 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 1800 UTC surface analysis and satellite imagery through 2345 UTC. ...SPECIAL FEATURES... Central Atlantic Gale Warning/Swell Event: A central Atlantic cold front extending from near 31N53W to 32N64W will enter the far northern central Atlantic forecast waters this evening. SW winds to gale-force are expected within around 90 nm ahead of the front north of 28N tonight. Winds will diminish below gale- force Sun morning as the front shifts southeastward. Meanwhile, a related large N swell will start impacting the waters east of 62W tonight and will subside by mid-week. This swell will produce seas 12 ft and up to around 20 ft south of 31N through Mon, then gradually subside afterward. Seas of 12 ft or greater will reach to 18N Mon night. Caribbean Gale Warning: The pressure gradient between high pressure of 1025 mb analyzed southwest of Bermuda near 30N71W and a 1010 mb Colombian Low will continue to support strong to near-gale force trades across the south-central Caribbean through tonight. Winds will peak at gale-force again tonight with seas reaching to 12 ft with the strongest winds. Gulf of America Gale Warning: A strong late-season cold front will emerge off of the Texas this evening, and and reach from central Louisiana to the western Bay of Campeche by Sun morning. Fresh to near gale N winds and rapidly building seas to around 11 ft will follow the front over the western Gulf Sun through Mon, with northerly gales expected briefly offshore of Tampico Sun morning, and off of Veracruz Sun afternoon. The cold front will reach from the Florida Panhandle to the eastern Bay of Campeche Mon morning, followed by fresh to strong N winds, Please refer to the latest NWS High Seas and Offshore Waters Forecasts issued by the National Hurricane Center, at website: https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml for more details on all three Gale Warnings. ...MONSOON TROUGH/INTERTROPICAL CONVERGENCE ZONE... The monsoon trough enters the Atlantic Ocean through the coast of Africa near 10N15W and continues southwestward to 02N18W, where it transitions to the ITCZ to below the Equator at 28W and continues to 02S34W to near the coast of Brazil near 02S47W. Scattered moderate to isolated strong convection is seen from 03N to 07N between 12W-19W. Scattered moderate convection is within 30 nm of 03N25W and of 02N31W. ...GULF OF AMERICA... A Gale Warning is in effect for the western Gulf of America. Please refer to the Special Features section for more details. Fresh to near gale-force southerly winds are across most of the basin, generated by a tight gradient between high pressure of 1025 mb over the western Atlantic near 30N71W and low pressure of 1006 mb analyzed in NE Mexico. This sustained southerly flow is producing seas of 8 ft and higher across most of the waters W of 85W and N of 21N, with peak seas around 11 ft. Seas are 5 to 8 ft are over the rest of the basin. Otherwise, a cold front has recently moved off the Texas coast, and extends from near Galveston/Houston to 27N97W, where it transitions to a warm front to inland NE Mexico. It curves to the northwest to near far northern Mexico. Significant deep convection associated with this frontal system is inland NE Texas, and stretching well northeastward to the central U.S. Latest satellite imagery and observations continue to reveal sea fog over most of the NW Gulf waters producing low visibility. For the forecast, a strong pressure gradient between the Bermuda High and low pressure extending from NE Mexico to the south- central U.S. will continue to force fresh to near-gale southerly winds across most of the Gulf basin through this evening. A strong late- season cold front will emerge off of the Texas coast this evening, and reach from central Louisiana to the western Bay of Campeche by Sun morning. Fresh to near gale N winds and rapidly building seas will follow the front over the western Gulf Sun through Mon, with northerly gales expected briefly offshore of Tampico Sun morning, and off of Veracruz Sun afternoon. The cold front will reach from the Florida Panhandle to the eastern Bay of Campeche Mon morning, followed by fresh to strong N winds, then weaken as it moves southeast of the area Tue. Weak high pressure will move eastward across the northern Gulf behind the front Tue night through Thu. ...CARIBBEAN SEA... A Gale Warning is in effect for the waters near the coast of Colombia. Please refer to the Special Features section for more details. Scatterometer satellite data passes from today highlighted a broad area of fresh to strong trades across most of the basin east of about 82W. This is due to a tight pressure gradient between high pressure north of the area and the Colombian low. Moderate to fresh east to southeast trades are west of 82W. Seas are 6 to 10 ft across the majority of the basin, with localized seas up to 12 ft offshore of northern Colombia. Isolated showers are possible east of 70W. For the forecast, a tight pressure gradient between western Atlantic high pressure and the Colombian Low will continue to produce strong trade winds across the central Caribbean, the Atlantic Passages and the Gulf of Honduras through Sun morning, with another pulse of gale-force winds expected offshore of Colombia tonight. Rough to very rough seas will accompany these winds. The Bermuda high will weaken and shift eastward late Sun through mid-week, leading to diminishing trades across the Caribbean. A cold front is expected to reach the northwest Caribbean Tue morning, with fresh to locally strong northerly winds filling in behind it. The front will move eastward and stall from central Cuba to NE Honduras and through Thu before dissipating. ...ATLANTIC OCEAN... A Gale Warning is in effect for the far NE Atlantic waters east of 40W. Please refer to the Special Features section for more details. In addition to the Special Features description of a central Atlantic cold front, a weakening cold front enters the eastern Atlantic waters through 31N19W, and continues southwestward to 26N30W to 24N40W and to near 22N50W. No significant convection is present this front. Moderate to fresh N to NE winds and 8 to 10 ft seas follow the front. The subtropical ridge is anchored by 1025 mb high pressure SW of Bermuda near 28N69W. This pattern is supporting fresh to strong E to SE winds and 8 to 10 ft seas from offshore of the northern portion of the Greater Antilles through the Bahamas. Mostly moderate winds and seas are noted elsewhere across the basin, except moderate to fresh S of 20N, where seas are 6 to 9 ft. For the forecast west of 55W, a broad ridge along 30N associated with the Bermuda High will continue to force fresh to strong trades and rough seas from offshore of the Lesser Antilles through the Bahamas and Straits of Florida through tonight. A frontal trough will rotate through the NE waters tonight, bringing fresh to strong winds there through tonight. Large N swell generated behind the front will start impacting the waters east of 65W tonight, then subside late Wed through Thu. Fresh to strong S winds will develop off the coast of northeast Florida tonight through Mon, ahead of a cold front moving through the southeastern United States. The front is forecast to move off of the east coast Mon night, and reach from Bermuda to central Cuba by mid-week, where it will stall and weaken. This front will be followed by fresh to strong NE winds and moderate to rough seas. $$ Aguirre WXTLIST: done
