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. ...SPECIAL FEATURE... Meteo-France has issued Gale warnings for the marine zones of Agadir from 12/09Z through 13/00Z, and Tarfaya from 12/15Z through 13/00Z. Please refer to the Meteo-France High Seas Forecast product, listed on the website at https://wwmiws.wmo.int. for more information. ...MONSOON TROUGH/ITCZ... A monsoon trough enters the Atlantic near the coastal border Gambia and southern Senegal, then extends southwestward to 02N25W. An ITCZ continues from 02N25W across 00N30W to near Sao Luis, Brazil. Scattered moderate to isolated strong convection is found near the ITCZ from 10N to 13N near the Africa coast from Guinea-Bissau northward to Gambia, and from 02S to 04N between 20W and 25W. Similar convection is also seen up to 230 nm along either side of the ITCZ. ...GULF OF AMERICA... A surface ridge reaches southwestward from a 1025 mb high near the Florida Panhandle to near Veracruz, Mexico. Fresh with locally strong NE to SE winds and seas of 4 to 6 ft are present at the northwestern Gulf, north of the Yucatan Peninsula and across the Florida Straits. Gentle winds and 1 to 3 ft seas are noted at the northeastern Gulf and the western Bay of Campeche. Gentle to moderate NE to SE winds and seas at 3 to 5 ft prevail for the rest of the Gulf. For the forecast, the aforementioned high will maintain mostly moderate to fresh E winds across the Gulf through tonight. It is expected to strengthen some through late Sun night, then weaken into midweek next week, while shifting southward over the western Atlantic. The ridge will persist across the Gulf through this period. A tightening pressure gradient between the ridge and lower pressure to its southeast associated with a frontal boundary will funnel pulsing fresh to strong E winds through the Florida Straits and into the southeastern Gulf starting on Sun. Seas across the Gulf will mostly be moderate, except reaching rough at times in the Florida Straits beginning on Mon. ...CARIBBEAN SEA... A robust trade-wind pattern continues across much of the Caribbean Sea. Convergent trades are causing scattered heavy showers and isolated thunderstorms off the coast of Costa Rica. Latest ASCAT satellite scatterometer and earlier altimetery data reveal fresh to strong NE winds and seas of 5 to 8 ft at the south-central basin, lee of Cuba and near the Windward Passage. Gentle to moderate NE to E winds and 2 to 4 ft seas exist at the north-central and northeastern basin. Moderate to fresh NE to E winds and seas at 4 to 6 ft prevail elsewhere in the Caribbean Sea, including the Gulf of Venezuela. For the forecast, building high pressure over the western Atlantic will increase winds across the Caribbean Sea, leading to strong winds and rough seas to 10 ft over the south-central basin into early next week. Fresh to strong NE winds and rising seas will prevail south of Cuba, in the Windward Passage, and south of Hispaniola starting tonight. Winds and seas will diminish late next week. ...ATLANTIC OCEAN... A nearly stationary front extends southwestward from east of Bermuda across 31N60W to the northern coast of the Dominican Republic. Convergent southerly winds are producing scattered moderate convection north of 24N between 56W and the front itself. Similar convection is also occurring over northern Hispaniola. Refer to the Monsoon Trough/ITCZ section at the beginning for additional convection in the Atlantic Basin. Moderate to fresh with locally strong NE winds and seas of 6 to 9 ft are evident behind the nearly stationary front, except seas are 4 to 6 ft in the Great Bahama Bank. Farther southeast, gentle winds and 5 to 7 ft seas in moderate mixed swells are noted north of 20N between 60W and the front. To the east, a broad Atlantic Ridge associated with a 1033 mb Azores High is supporting gentle to moderate E to SSE winds with seas at 6 to 8 ft in large NE to E swell dominate north of 20N between 35W and 60W. Moderate with locally fresh ENE to ESE winds and 6 to 8 ft seas prevail for the remainder of the Atlantic Basin west of 35W. For the forecast west of 55W, the fresh to locally strong NE winds will expand in coverage from Sun through Mon night as the northern portion of the frontal boundary transitions back to a cold front reaching waters near 55W by late Mon. The winds will then diminish to mostly fresh starting Tue south of 28N as the high pressure weakens, with an associated ridge near 31N. Rough seas from large NE swell will linger through Tue between Bermuda and the Bahamas. $$ Chan ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXNT20KNHC120954_C_KWBC_20260412095521_9109880-1027-TWDAT.txt ****0000005985**** AXNT20 KNHC 120954 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1215 UTC Sun Apr 12 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.

Please refer to the Meteo- France High Seas Forecast product, listed on the website at https://wwmiws.wmo.int. for more information. ...MONSOON TROUGH/ITCZ... The monsoon trough axis enters the Atlantic near the coastal border Gambia and southern Senegal, then extends southwestward to 03N25W, where it transitions to the ITCZ to the Equator at 30W and continues to 03S38W and to near Sao Luis, Brazil. Scattered moderate to isolated strong convection is from the Equator to 04N between 23W and 27W. Scattered moderate convection is within 120 nm northwest of the ITCZ between 25W and 34W, and within 90 nm north of the ITCZ between 34W and 39W. ...GULF OF AMERICA... A broad ridge extends from a 1025 mb high center that is offshore the Carolinas southwestward to the western Gulf. The related gradient is generally allowing for mostly fresh easterly winds across the basin. Both buoy observations indicate seas of 4 to 6 ft over the basin. Higher seas of 7 to 10 ft are in the Straits of Florida, where strong northeast to east winds are present. Much lower seas of 1 to 3 ft are in the far northeast Gulf, where light to gentle east winds exist. For the forecast, the high pressure center of the Carolinas will begin to slide eastward into the western Atlantic starting this evening. A ridge will extend southwestward from the high to the north-central Gulf through the forecast period. The related gradient will maintain moderate to fresh east winds across the basin through Wed. Afterward, the high pressure will be weakening allowing for winds over the area to diminish to gentle to moderate speeds. Pulsing fresh to strong east winds will surge through the Straits of Florida and into the southeastern Gulf starting today. Seas across the basin will be at a mostly moderate state, except reaching a rough state, at times, in the Straits of Florida beginning on Mon. Seas subside around midweek. ...CARIBBEAN SEA... Overnight scatterometer satellite data shows fresh to strong northeast winds south of about 15N between 72W and 79W and in the Gulf of Venezuela. Seas are to 8 ft with these winds. The scatterometer satellite data also shows a swath of fresh to strong northeast winds in the lee of Cuba and through the Windward Passage. Moderate to fresh trades are elsewhere south of 16N east of 75W and also west of 80W. Seas are 4 to 6 ft with these winds. Lighter trades of gentle speeds are north of 16N east of 75W winds and just south of Jamaica. Gentle to moderate trades are in the Gulf of Honduras. Seas are 3 to 5 ft in the Gulf of Honduras. Convergent trades are helping to sustain scattered showers and thunderstorms along and offshore the coast of Costa Rica. For the forecast, high pressure over the western Atlantic will maintain fresh to strong east winds and rough seas over the south- central portion of the basin and near Colombia through the early part of the week. Fresh to strong northeast winds and building seas will prevail south of Cuba, in the Windward Passage, and south of Hispaniola through most of the upcoming week. Winds and seas will diminish late in the week. ...ATLANTIC OCEAN... A nearly stationary front extends southwestward from 31N59W to 26N63W, and to the north-central portion of the Dominican Republic. Convergent southerly winds are producing scattered moderate convection within 240 nm east of the front north of 26N, and within 150 nm east of the front south of 26N. Scattered showers and isolated thunderstorms are evident along and just inland the coast of Hispaniola. A trough is analyzed over the western Atlantic from near 29N73W to 25N72.5W. Isolated showers have recently developed from 25N to 27N between 72W and 74W. Overnight scatterometer satellite data reveals fresh to locally strong northeast winds behind the front. Seas with these winds are in the range of 7 to 10 ft between the front and the Bahamas. Lower seas of 5 to 7 ft are west of the Bahamas, but occasionally to 9 ft in the Straits of Florida. To the east of the front, the basin is dominated by a broad area of high pressure that is associated to a strong Azores high center of 1032 mb. The pressure gradient between the high pressure and relatively lower pressure to its south is generally supporting moderate to fresh trades east of 60W, where seas are 7 to 9 ft in long-period northeast swell. An area of light to gentle winds is between the front and 60W. Seas are 5 to 7 ft mixed north and east swell within this area. For the forecast west of 55W, the fresh to locally strong northeast winds behind the aforementioned front will expand in coverage through Mon night as the northern portion of the frontal boundary transitions back to a cold front as it reaches the northeast forecast late on Mon. The winds then diminish to mostly fresh speeds starting Tue south of 28N as the high pressure weakens, with an associated ridge near 31N. Rough seas from large northeast swell will linger into the start of next week between Bermuda and the Bahamas. $$ Aguirre ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXNT20KNHC121030_C_KWBC_20260412103122_9109880-1030-TWDAT.txt ****0000006018**** AXNT20 KNHC 121030 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1215 UTC Sun Apr 12 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.

Surface ridging prevails across the basin, extending from a 1034 mb high pressure system centered near 41N68W. Moderate to fresh easterly winds and moderate seas prevail across the basin. Generally dry conditions are occurring over the Gulf waters. For the forecast, high pressure centered over the western Atlantic will maintain moderate to fresh E to SE winds and mostly moderate seas through Fri. Expect stronger winds to pulse across the Florida Straits through the early part of the week, and off the Yucatan Peninsula mainly night through mid week. ...CARIBBEAN SEA... The tight pressure gradient between the strong ridge north of the Caribbean and lower pressures in NW South America results in fresh to strong NE-E winds and rough seas in the south-central Caribbean. Moderate to fresh NE winds and moderate seas are found in the NW Caribbean and Windward Passage. Elsewhere, moderate or weaker winds and moderate seas are prevalent. No significant weather are occurring in the basin. For the forecast, high pressure over the western Atlantic will maintain fresh to strong east winds and rough seas over the south-central portion of the basin and near Colombia through the early part of the week. Fresh to strong northeast winds and building seas will prevail south of Cuba, in the Windward Passage, and south of Hispaniola through most of the upcoming week. Winds and seas will diminish late in the week. ...ATLANTIC OCEAN... Please read the Special Features section for details on the Gale Warning off Morocco. A cold front enters the basin near 31N57W and continues southwestward to a 1016 mb low pres near 26N62W, then a stationary front follows to northern Hispaniola. Scattered showers and isolated thunderstorms are present near these boundaries. A tight pressure gradient between the strong ridge over NE England and the aforementioned fronts sustains fresh to strong NE winds and rough seas across much of the waters behind these boundaries. The remainder of the tropical Atlantic is dominated by a broad subtropical ridge near the Azores. Fresh to strong NE-E winds and rough seas to 10 ft are observed north of 10N and east of 40W. The strongest winds and highest seas are found in the far NE Atlantic. Moderate to fresh easterly trade winds and seas of 7-9 ft are noted south of 20N and west of 40W. Elsewhere, moderate or weaker winds and moderate seas prevail. For the forecast west of 55W, the front will dissipate through the early part of the week. Fresh to strong NE winds and rough seas persist west of the front mainly south of 27N through mid week, then diminishing through Fri. $$ ERA ########################### END OF MESSAGE SET ############################
