--------------------------------------------------------------------------- TROPICAL WEATHER DISCUSSION (NORTH ATLANTIC AREA) MESSAGES T1T2: AX A1A2: NT Date: 2026-04-24 --------------------------------------------------------------------------- Message File: T_AXNT20KNHC240359_C_KWBC_20260424035957_47448518-1821-TWDAT.txt ****0000005302**** AXNT20 KNHC 240359 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0615 UTC Fri Apr 24 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 0000 UTC surface analysis and satellite imagery through 0355 UTC. ...MONSOON TROUGH/ITCZ... A monsoon trough enters the Atlantic along the coast of Guinea near 11N15W, then curves southwestward to 00N35W. The ITCZ extends from 02N22W to 00N50W. Scattered moderate to isolated strong convection is observed south of 05N and east of 30W. ...GULF OF AMERICA... A few showers are seen over the SE Gulf waters, especially close to the coast of Cuba. Generally dry conditions are noted elsewhere. Moderate to fresh easterly winds and moderate seas are found in the eastern Bay of Campeche and SE Gulf. However, mariners may experience stronger gusts associated with the stronger convection. In the remainder of the basin, moderate or lighter winds and slight to moderate seas prevail. Satellite images indicate that smoke from agricultural fires in SE Mexico is affecting the SW Gulf waters. Mariners may experience diminished visibility in the area. For the forecast, high pressure will prevail across the Gulf region, with a relatively weak pressure gradient across the area. This will result in gentle to moderate SE winds and moderate seas basin-wide through the weekend into the early part of next week. The exception will be off the Yucatan Peninsula, where a diurnal trough will pulse moderate winds to fresh during the evenings. Meanwhile, gusty winds, frequent lightning, and higher seas are likely in an area of showers and thunderstorms currently located over the far SE Gulf and the Florida Straits, which is moving eastward tonight. ...CARIBBEAN SEA... A few showers and isolated thunderstorms are occurring north of 18N due to a stationary front draped across Hispaniola and between eastern Cuba and Jamaica and divergence aloft. Meanwhile, drier weather conditions evident in the rest of the basin. The pressure gradient between a weak ridge to the north of the islands and the frontal boundary supports fresh to locally strong NE-E winds and moderate seas in the Windward Passage. Moderate to locally fresh easterly winds and slight seas are found in the lee of Cuba. Elsewhere, moderate or lighter winds and slight to moderate seas are prevalent. For the forecast, high pressure located N of the basin will weaken over the next couple of days as the remnants of a frontal boundary, currently located north of Hispaniola and Puerto Rico, lifts northward as a trough during the upcoming weekend. This weather pattern will support a weaker than usual pressure gradient across the Caribbean Sea into the weekend, resulting in mainly gentle to moderate winds and slight to moderate seas across the entire basin. ...ATLANTIC OCEAN... A weak cold front extends from a low pressure near the Azores to 31N42W and to 26N51W, followed by a stationary front to Hispaniola. A few showers are noted near this boundary. Moderate to fresh southerly winds and seas of 5-8 ft are present ahead of the front to 31W and north of 27N. Rough seas are noted behind the front to 51W and north of 27N. Moderate to locally fresh easterly winds and moderate seas are evident south of 25N and west of 60W. The remainder of the SW North Atlantic, west of 55W, is dominated by a broad subtropical ridge. The central and eastern Atlantic are under the influence of a 1020 mb high pressure system near 27N30W. The pressure gradient between this ridge and lower pressures in western Africa support moderate to fresh northerly winds and seas of 6-8 ft from 08N to 27N and east of 23W. Elsewhere, moderate or weaker winds and moderate seas prevail. A cold front extends southwestward from a 1001 mb low north of the area near 38N40W south-southwestward to 31N45W and to 25N53W, where it transitions to a stationary front to 20N61W and to across north-central Hispaniola and to Haiti. A trough extends from the northern Leeward Islands to near 15N65W. Isolated showers are possible near the trough. For the forecast west of 55W, a cold front extends from near 31N41W to 25N50W where it becomes a stationary front to Hispaniola near 19N69W. The front will remain nearly stationary just N of Hispaniola and Puerto Rico on Fri. The remnant moisture associated with the frontal boundary will lift northward as a trough Sat through Sun. A weak low may develop along the trough axis E of the Bahamas on Sun. This will support gentle to moderate winds with slight to moderate seas across most of the forecast area through the weekend. The exception will be over the NE waters where fresh to locally strong westerly winds and rough seas are expected beginning on Fri as another cold front clips the region by late Sat into Sun. $$ Delgado ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXNT20KNHC241034_C_KWBC_20260424103503_49676782-1854-TWDAT.txt ****0000004601**** AXNT20 KNHC 241034 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1215 UTC Fri Apr 24 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 0600 UTC surface analysis and satellite imagery through 1020 UTC. ...MONSOON TROUGH/ITCZ... A monsoon trough enters the Atlantic along the coast of Guinea near 11N15W, then curves southwestward to 00N26W. The ITCZ extends from 00N26W to 02S40W to 00S50W. Scattered moderate to isolated strong convection is observed from 04S to 10N between 06W and 26W. Scattered moderate convection is from 08S to 04N between 25W and 38W, and from 02S to 12N W of 45W. ...GULF OF AMERICA... Scattered to isolated showers continue to move eastward away from the Florida Straits this morning while dense fog was repored over the NW Gulf offshore waters. A 1019 mb high NE of the northern Bahamas extends a ridge across Florida and into the western Gulf. A weak pressure gradient over the region is supporting gentle to moderate SE winds and slight to moderate seas. Otherwise, satellite images indicate that smoke from agricultural fires in SE Mexico is affecting the SW Gulf waters. Mariners may experience diminished visibility in the area. For the forecast, high pressure will prevail across the Gulf region, with a relatively weak pressure gradient across the area. This will result in gentle to moderate SE winds and moderate seas basin-wide through Mon. The exception will be off the Yucatan Peninsula, where a diurnal trough will pulse moderate winds to fresh during the evenings. Southeasterly winds are forecast to reach moderate to fresh speeds over the western half of Gulf Mon night into mid-week. ...CARIBBEAN SEA... A few showers and isolated thunderstorms are occurring in the lee side of central and eastern Cuba as well as the Windward Passage due to the tail of a dissipating stationary front that extends across Hispaniola to the offshore waters of southern Cuba. Otherwise, a 1019 mb high is NE of the northern Bahamas and is supporting moderate or lighter winds and slight to moderate seas basin-wide. For the forecast, high pressure located N of the basin will weaken over the next couple of days as the remnants of a frontal boundary, currently located north of Hispaniola and Puerto Rico, lifts northward as a trough during the upcoming weekend. This weather pattern will support a weaker than usual pressure gradient across the Caribbean Sea into Mon, resulting in mainly gentle to moderate winds and slight to moderate seas across the entire basin. Winds are forecast to reach moderate to fresh speeds over the central and eastern Caribbean Mon night through mid-week. ...ATLANTIC OCEAN... A cold front extends from near 31N39W to 26N47W where it becomes a dissipating stationary front to Hispaniola near 19N69W. The front is supporting scattered showers in the Great Bahama Bank while an area of showers continue to migrate from the Florida Straits to the northern Bahamas. Between the front and the areas of showers is a 1019 mb high NE of the northern Bahamas, which is supporting moderate or lighter E to SE winds and slight to moderate seas across the SW N Atlantic waters. Another 1019 mb high is E of the front over the E subtropical Atlantic waters, which is supporting moderate to fresh SW winds ahead of the front to 30W and N of 26N. Seas with these winds are 5 to 8 ft. Moderate to fresh NNE winds are between the Canary and Cape Verde Islands, and the coast of NW Africa with moderate seas. Otherwise, moderate or weaker winds and moderate seas are elsewhere. For the forecast west of 55W, the aforementioned front will dissipate today and the remnant moisture will lift northward as a trough Sat through Sun. A weak low may develop along the trough axis E of the Bahamas on Sun. This will support gentle to moderate winds with slight to moderate seas across most of the forecast area through the weekend. The exception will be over the NE waters where fresh to locally strong westerly winds and rough seas are expected beginning today as another cold front clips the region by late Sat into Sun. $$ Ramos ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXNT20KNHC241703_C_KWBC_20260424170406_49676782-1867-TWDAT.txt ****0000004367**** AXNT20 KNHC 241703 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1815 UTC Fri Apr 24 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 1200 UTC surface analysis and satellite imagery through 1700 UTC. ...MONSOON TROUGH/ITCZ... A monsoon trough enters the Atlantic near 08N13W, then curves southwestward to 02S23W. The ITCZ extends from 02S23W to 04S36W. Numerous moderate to isolated strong convection is observed from 02N to 07N and east of 15W. Numerous moderate convection is from 07S to 02S between 23W and 36W. ...GULF OF AMERICA... Scattered to isolated showers and thunderstorms continue to move eastward into the Florida Straits. A 1017 mb high NE of the northern Bahamas extends a ridge across Florida and into the central Gulf. A weak pressure gradient over the region is supporting gentle to moderate SE winds and slight to moderate seas. For the forecast, high pressure will prevail across the Gulf region, with a relatively weak pressure gradient across the area. This will result in gentle to moderate SE winds and moderate seas basin-wide through Mon. The exception will be off the Yucatan Peninsula, where a diurnal trough will pulse moderate winds to fresh during the evenings. Southeasterly winds are forecast to reach moderate to fresh speeds over the western half of Gulf Mon night into mid-week. ...CARIBBEAN SEA... Showers and thunderstorms are occurring in the lee side of central Cuba, and eastern Cuba as well as the Windward Passage due to a surface trough over the area. Otherwise, a 1017 mb high is NE of the northern Bahamas and is supporting mainly gentle E to SE winds and slight to moderate seas basin- wide. For the forecast, high pressure located N of the basin will weaken over the next couple of days as the remnants of a frontal boundary, currently located north of Puerto Rico, Hispaniola and eastern Cuba, lifts northward as a trough during the upcoming weekend. This weather pattern will support a weaker than usual pressure gradient across the Caribbean Sea into Mon, resulting in mainly gentle to moderate winds and slight to moderate seas across the entire basin. Winds are forecast to reach moderate to fresh speeds over the central and eastern Caribbean Mon night through mid-week. ...ATLANTIC OCEAN... A surface trough, remnants of a frontal boundary, is analyzed from 24N53W to 21N70W to 22N78W. The trough is supporting scattered showers in the Great Bahama Bank while an area of showers and thunderstorms continue to migrate from the Florida Straits to the northern Bahamas. Between the trough and the areas of showers is a 1017 mb high NE of the northern Bahamas, which is supporting moderate or lighter NE to E winds and slight to moderate seas across the SW N Atlantic waters. A weakening cold front extends from 31N39W and extends to 28.5N45W. East of this front, a 1021 mb high is centered near 27N26W. The pressure gradient between these features is supporting moderate to fresh SW winds ahead of the front to 40W and N of 25N. Seas with these winds are 5 to 9 ft. Moderate to fresh NE winds are between the Canary and Cape Verde Islands, and the coast of NW Africa with moderate seas. Otherwise, moderate or weaker winds and moderate seas are elsewhere. For the forecast west of 55W, the aforementioned trough will lift northward this weekend. A weak low may develop along the trough axis E of the Bahamas on Sun. This will support gentle to moderate winds with slight to moderate seas across most of the forecast area through the weekend. The exception will be over the NE waters where fresh to locally strong westerly winds and rough seas are expected beginning today as another cold front clips the region by late Sat into Sun. A third cold front will enter the waters off NE Florida by Sun night, and extend from 31N68W to South Florida by Mon night. $$ KRV ########################### END OF MESSAGE SET ############################
