--------------------------------------------------------------------------- TROPICAL WEATHER DISCUSSION (NORTH ATLANTIC AREA) MESSAGES T1T2: AX A1A2: NT Date: 2026-04-27 --------------------------------------------------------------------------- Message File: T_AXNT20KNHC270503_C_KWBC_20260427050426_47448518-2069-TWDAT.txt ****0000004997**** AXNT20 KNHC 270503 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0615 UTC Mon Apr 27 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 0500 UTC. ...MONSOON TROUGH/ITCZ... The monsoon trough enters the Atlantic near 12N16W and continues southwestward to near 03N20W and then to 00S39W. The ITCZ then continues from that point to the coast of Brazil near 02S45W. Numerous moderate to strong convection is seen S of 09N and E of 20W. Scattered moderate convection is seen S of 05N between 20W and 40W. ...GULF OF AMERICA... Satellite imagery shows low clouds and fog forming in the W Gulf generally N of 23N and W of 92W, so low visibility may be a concern in this region. Surface ridging prevails with a weak 1013 mb high analyzed over the eastern Gulf. Moderate to fresh E winds prevail along the northern Yucatan Peninsula and W of 90W, with gentle to moderate of weaker winds elsewhere. Slight seas prevail basin- wide. For the forecast, a ridge across the E Gulf waters, combined with a surface trough along the coast of Mexico reaching offshore Veracruz will support moderate to fresh southeast winds and moderate seas over the western half of the Gulf, and gentle to moderate winds with slight to moderate seas over the eastern part of the basin through the middle of the week. In addition, a diurnal trough will pulse moderate to fresh winds off the Yucatan Peninsula during the evenings through Fri night. Looking ahead, a cold front will enter the northern Gulf Wed night into Thu. ...CARIBBEAN SEA... A surface trough analyzed from the Leeward Islands to the coast of Venezuela is supporting scattered showers and thunderstorms across much of the eastern Caribbean. A relatively weak pressure pattern exists across the basin, moderate to fresh trades occurring offshore NW Colombia and in the Gulf of Honduras, with gentle to moderate or weaker winds elsewhere. Slight seas prevail basin- wide. For the forecast, a surface trough meandering across the Atlantic waters north of the Greater Antilles will continue to contribute to a weaker than usual pressure gradient across the central and eastern Caribbean Sea into Mon resulting in mainly moderate or weaker winds and slight to moderate seas, except in the Gulf of Honduras where moderate to fresh east winds and moderate seas are expected. Winds are forecast to reach moderate to fresh speeds over the eastern and central Caribbean Mon night through Thu as high pressure again builds north of the area in the wake of a cold front that will be moving across the western Atlantic. ...ATLANTIC OCEAN... A warm front is analyzed from a 1012 mb low near 23N68W to near 23N54W. A frontal remnant trough is then analyzed from that point to near 31N39W. Widely scattered showers and thunderstorms are seen along and north of the warm front to about 27N. In the west Atlantic, a surface trough is analyzed along the eastern FL coast. Scattered moderate convection is developing along this trough as a frontal boundary lingers to the north. In the central Atlantic, another frontal remnant trough extends from 31N42W to 28N58W. Seas of 7-9 ft follow this feature. Away from these features, surface ridging prevails with moderate to fresh trades across much of the Atlantic S of 20N and E of 60W, as well as N of 20N and E of 30W. Moderate or weaker winds prevail elsewhere. Seas of 4-7 ft also prevail across much of the basin away from the enhanced seas behind a frontal remnant trough mentioned above, and W of 70W where slight seas prevail. For the forecast west of 55W, a remnant frontal trough lingering north of the Greater Antilles will gradually dissipate through Mon. Moderate to fresh east to southeast winds north of 25N east of 69W will gradually shift northeastward through Tue ahead of a cold front while increasing to fresh to strong speeds. A cold front over the waters east of northeast Florida will reach from near Bermuda to South Florida by Mon night, from near 31N59W to 25N64W and weakening to the central Bahamas late Tue before shifting east of 55W early on Wed. Moderate to fresh northerly winds, and moderate to rough seas are expected north of 27N in the wake of the front through Mon night. Looking ahead, another cold front is expected to move off the northeast Florida late Thu or Thu night, and weaken as it reaches from near Bermuda to 28N72W and stationary to South Florida late Fri. $$ Adams ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXNT20KNHC270947_C_KWBC_20260427094727_47448518-2083-TWDAT.txt ****0000006237**** AXNT20 KNHC 270947 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1215 UTC Mon Apr 27 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 0930 UTC. ...MONSOON TROUGH/ITCZ... The monsoon trough axis enters the Atlantic near 12N16W and continues southwestward to near 03N20W and to 00S39W, where it transitions to the ITCZ to the coast of Brazil near 02S45W. Numerous moderate to strong convection is within 60 nm of the trough between 16W-19W. Scattered moderate to isolated strong convection is within 60 nm of the trough between 20W-25W. Scattered moderate convection is from 06N to 09N between 14W-16W, within 60 nm south of the trough between 28W-34W and within 60 nm north of the trough between 31W-35W. ...GULF OF AMERICA... A weak 1015 mb high analyzed over the eastern Gulf at 27N86W maintains a weak pressure pattern over the eastern and central Gulf. A trough extends from Tampico, Mexico southeastward along the coast to Veracruz. The gradient in place is allowing for moderate to fresh east winds west of the Yucatan Peninsula and west of 90W, with light to gentle anticyclonic winds east of 90W. Seas of 3 to 5 ft are across the basin. Patches of low stratus-type clouds and fog producing visibility of 3 to 5 nm are seen over the far western Gulf and lifting to the northwest with the moderate to fresh southeasterly flow over that is occurring over that part of the Gulf. For the forecast, the interaction between weak high pressure over the eastern Gulf and a trough that extends from along the coast of Mexico from Tampico to Veracruz will produce moderate to fresh southeast winds and moderate seas over the western half of the Gulf, and gentle to moderate winds with slight to moderate seas over the eastern part of the basin through early Wed. Elsewhere, a diurnal trough will pulse moderate to fresh winds off the Yucatan Peninsula during the evenings through Fri night. Looking ahead, a cold front will enter the northern Gulf Wed night into Thu and reach from South Florida to central Texas by late Fri. ...CARIBBEAN SEA... A trough analyzed from the Leeward Islands to the coast of Venezuela in combination with a broad upper-level trough is supporting scattered showers and thunderstorms across much of the eastern Caribbean. A relatively weak pressure across the basin is keeping moderate to fresh trades offshore NW Colombia and in the Gulf of Honduras, and gentle to moderate or weaker winds elsewhere. Slight seas prevail basin-wide per latest altimeter satellite data passes and recent buoy observations. For the forecast, a surface trough meandering across the Atlantic waters north of the Greater Antilles will continue to contribute to a weaker than usual pressure gradient across the central and eastern Caribbean Sea today resulting in mostly moderate or weaker winds and slight to moderate seas, except in the Gulf of Honduras where moderate to fresh east winds and moderate seas are expected through the week. Winds are forecast to reach moderate to fresh speeds over the eastern and central Caribbean tonight through Thu as high pressure again builds north of the area in the wake of a cold front that will be moving across the western Atlantic. ...ATLANTIC OCEAN... A cold front extends from near 31N37W to 27N42W, where it becomes a trough to 22N50W and a dissipating warm front to 24N60W and to 24N65W. A trough extends from 24N65W to eastern Cuba. A trough is analyzed from near 31N40W to 27N50W and northwestward to 29N60W. Seas of 8 to 9 ft in long-period northwest swell follow the trough. Patches of rain along with isolated showers and thunderstorms are noted from 20N to 28N between 49W and 62W. Scattered showers and thunderstorms are from 24N to 29N between 64W and 68W. A cold front moved off the southeastern United States coast during the overnight hours, and is along a position from near 31N73W to inland to the extreme northeast part of northern Florida. A trough is to its south from 30N78W to just east of the upper Florida Keys. Scattered showers and thunderstorms are seen from 27N to 30N between 74W and 77W and north of 30N between 70W and 74W. Fresh to strong northeast winds are behind the front along with seas of up to around 7 ft. Otherwise, high pressure is the main feature over the eastern part of the basin as a 1020 mb high center is analyzed near 30N26W. The related gradient is keeping moderate to fresh trades over most of the basin south of about 20N and east of 60W, as well as north of 20N and east of 30W. Seas with these trades are 5 to 7 ft. Moderate or weaker winds prevail elsewhere, with seas 4 to 6 ft, except for slightly higher seas of 5 to 7 ft elsewhere north of 26N between 39W and 56W. For the forecast west of 55W, a weakening remnant frontal trough lingering north of the Greater Antilles will dissipate this morning. Moderate to fresh east to southeast winds north of 25N east of 69W will gradually shift northeastward through Tue ahead of a cold front while increasing to fresh to strong speeds. A cold front extending from 31N76W to northeast Florida will reach from near Bermuda to South Florida by tonight, then from near 31N59W to 25N64W and weakening to the central Bahamas late Tue before shifting east of 55W early on Wed. Moderate to fresh northerly winds, and moderate to rough seas are expected north of 27N in the wake of the front through tonight. Looking ahead, another cold front is expected to move offshore northeast Florida late Thu or Thu night, and weaken as it reaches from near Bermuda to 28N72W and stationary to South Florida late Fri. $$ Aguirre ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXNT20KNHC271001_C_KWBC_20260427100138_49676782-2065-TWDAT.txt ****0000006254**** AXNT20 KNHC 271001 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1215 UTC Mon Apr 27 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.

Slight seas prevail basin-wide per latest altimeter satellite data passes and recent buoy observations. For the forecast, high pressure will build north of the area, tightening the pressure gradient through today. The tighter pressure gradient will support moderate to fresh wind speeds over the eastern and central Caribbean tonight through Thu, reaching locally strong at times. In the Gulf of Honduras, moderate to fresh east winds and moderate seas are expected through Fri, increasing to fresh to strong speeds through Sat. ...ATLANTIC OCEAN... A low pres is analyzed near 30N36W, with cold front from the low to 24N43W. A surface trough continues from that point to 23N72W. Scattered showers are noted along these features. Seas to 8 ft in long-period northwest swell follow the front/trough. To the west, a cold front moved off the southeastern United States coast during the overnight hours, analyzed in our area from 31N75W to 29N81W. Scattered showers and thunderstorms are noted from 26N to 31N between 72W and 79W. Fresh to strong northeast winds are behind the front along with seas of up to around 8 ft. Otherwise, high pressure is the main feature over the eastern part of the basin. The related gradient is keeping moderate to fresh trades over most of the basin south of about 20N and east of 60W, as well as north of 20N and east of 30W. Seas with these trades are 5 to 7 ft. Moderate or weaker winds prevail elsewhere, with seas 4 to 6 ft, except for slightly higher seas of 5 to 7 ft elsewhere north of 26N between 39W and 56W. For the forecast west of 55W, the cold front will reach from near Bermuda to South Florida by tonight, then from near 31N59W to 25N64W and weakening to the central Bahamas late Tue before shifting east of 55W early on Wed. Moderate to fresh northerly winds, and moderate to rough seas are expected north of 27N in the wake of the front through tonight. Another cold front is expected to move offshore northeast Florida late Thu or Thu night, and weaken as it reaches from near Bermuda to 28N72W and stationary to South Florida late Fri. $$ ERA ########################### END OF MESSAGE SET ############################
