--------------------------------------------------------------------------- TROPICAL WEATHER DISCUSSION (NORTH ATLANTIC AREA) MESSAGES T1T2: AX A1A2: NT Date: 2026-04-06 --------------------------------------------------------------------------- Message File: T_AXNT20KNHC060559_C_KWBC_20260406060042_9109880-652-TWDAT.txt ****0000004082**** AXNT20 KNHC 060559 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0615 UTC Mon Apr 6 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 0550 UTC. ...MONSOON TROUGH/ITCZ... The monsoon trough reaches the Atlantic through the coast of Sierra Leone near 09N13W and continues southwestward to 04N21W. The ITCZ extends from 04N21W to 01N36W to Brazil near 01S50W. Scattered moderate convection is from 06S to 04N W of 26W. ...GULF OF AMERICA... A cold front extends from near Apalachicola, Florida, to south of Tampico, Mexico. Recent scatterometer data show strong to near gale force N to NW winds W and NW of the front across the offshore waters N of Veracruz, Mexico and offshore Texas and Louisiana. The front is also supporting scattered heavy showers from the Florida Panhandle offshores to the NW Gulf offshore waters. Seas behind the front are 8 to 11 ft based on the latest altimeter data. Ahead of the front, winds are gentle to locally moderate from the NE and seas are slight. For the forecast, the cold front will move slowly SW and stretch from near Tampa Bay to the central Bay of Campeche by Mon night. The front will then stall Tue night into Thu from SW Florida into the SW basin. Scattered thunderstorms with locally gusty winds will accompany the front. Strong NE winds and rough seas will continue in the western Gulf behind the front through Mon, then strong NE winds will develop in the NE basin N of the boundary Tue through Thu. Conditions will improve some Fri and Fri night as high pressure from the eastern U.S builds southwestward toward the northern Gulf. ...CARIBBEAN SEA... The pressure gradient between subtropical Atlantic high pressure and the Colombian low continues to support moderate to fresh trades across the central and eastern basin where seas are moderate to 6 ft. Elsewhere, winds are mainly gentle from the NE and seas are slight. For the forecast, high pressure north of the basin will shift eastward into Mon allowing for pulsing strong winds and rough seas offshore Colombia to diminish. A trough just north of the Windward Passage will meander into mid-week, maintaining fresh trade winds across the eastern Carribbean, with mainly gentle winds to the west. Winds will likely increase again in the south- central Caribbean starting Wed night as a new high pressure builds southward from the western Atlantic. ...ATLANTIC OCEAN... A broad subtropical ridge covers the region and support moderate to fresh NE to E winds across the central subtropical waters along with moderate seas to 7 ft. Over the SW N Atlantic waters, winds are also moderate to fresh from the E to SE, and seas are moderate to rough in decaying NE swell E of the Bahamas. Otherwise, over the far E Atlantic, winds are moderate or weaker from the N to NE and seas are moderateb to 6 ft. For the forecast west of 55W, a cold front will move offshore the SE coast late tonight, then move slowly SE and reach 31N75W to near Melbourne, Florida, by Tuesday morning, and Bermuda to South Florida by Wed morning, before stalling. Low pressure is likely to form along the front NE of the Bahamas Tue night, then accelerate NE toward Bermuda into Wed. The gradient between this low and high pressure building into the SE U.S. in the wake of the front will lead to widespread near-gale-force NE to E winds behind the front, along with very rough seas. Mariners are advised to keep up with the latest forecast, and stay informed for the possibility of gale conditions developing as early as Tue. $$ Ramos ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXNT20KNHC061004_C_KWBC_20260406100547_9109880-663-TWDAT.txt ****0000004578**** AXNT20 KNHC 061004 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1215 UTC Mon Apr 6 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. ...SPECIAL FEATURES... Atlantic Gale Warning: A cold front will move offshore the SE U.S. coast today, then move slowly SE and reach from 31N72W to South Florida by Tue, then stall from Bermuda to the Florida Straits Wed. Low pressure is forecast to form along the front in the vicinity of the Bahamas on Tue, then accelerate NE along the boundary and out of the basin toward Bermuda by Wed. As the pressure gradient increases behind this low and strong high pressure building into the SE U.S., already strong NE winds N and W of the front will increase further, with gales developing Tue afternoon offshore NE Florida, then spreading east between the Bahamas and Bermuda Tue night into Wed. Very rough seas in excess of 15 kt are likely in the area of gales. With the frontal boundary remaining nearly stationary late this week, conditions will be slow to improve. Please read the latest High Seas Forecast issued by the National Hurricane Center at website: https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml ...MONSOON TROUGH/ITCZ... The monsoon trough reaches the Atlantic through the coast of Sierra Leone near 09N13W and continues southwestward to 04N21W. The ITCZ extends from 04N21W to 01N45W. Only isolated convection exists within about 150 nm of both of these features. ...GULF OF AMERICA... A cold front extends from Apalachicola Bay to just north of Veracruz, Mexico. Strong to near gale force N winds are N of the front within 150 nm of the Mexican coast as well as with 180 nm of the Texas and Louisiana coasts. Scattered moderate convection is noted ahead of the front from the Bay of Campeche northward to around 27N between 91W and 96W. Seas where the strong winds exist are 8 to 11 ft. S and E of the front, gentle winds and slight seas prevail. For the forecast, the cold front will move slowly SE and reach from SW Florida to the eastern Bay of Campeche tonight, then drift slowly SE of the basin Tue and Tue night. Thunderstorms with locally gusty winds will accompany the front. Strong NE winds and rough seas will continue in the western Gulf behind the front through tonight, then strong NE winds will develop in the NE basin, as low pressure develops in the Atlantic after the front exits the Gulf of America. Conditions will improve some Fri and Fri night as high pressure from the eastern U.S builds southwestward toward the northern Gulf. ...CARIBBEAN SEA... A benign trade wind dominant weather pattern prevails through the basin, with moderate to fresh E winds through the central and eastern basin, and gentle NE winds in the west. Moderate seas are present, except for slight in the NW basin. For the forecast, a trough oriented north of Haiti will meander into mid-week, disrupting the typical pressure gradient through the basin and leading to mainly gentle winds over the western basin, with moderate to fresh winds over the eastern Caribbean. By Wed night, strong high pressure building south toward the region will replace the trough and winds in the south-central Caribbean will increase to fresh to strong. ...ATLANTIC OCEAN... See Special Features section above for information on a Gale Warning that has been issued for portions of the SW Atlantic starting Tuesday. A broad subtropical ridge covers the region and support moderate to fresh NE to E winds across the central subtropical waters along with seas to 7 ft. Over the SW N Atlantic waters, rough seas in decaying NE to E swell exist E of the Bahamas. A weak trough along 70W is inducing scattered moderate convection N of the Antilles to 24N between 62W and 77W. For the forecast west of 55W, hazardous marine conditions are expected this week NW of a line from 31N60W to the SE Bahamas, as very rough seas and gale conditions will impact some areas. Details can be found in the Special Features section above. $$ Konarik ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXNT20KNHC061752_C_KWBC_20260406175214_38666572-641-TWDAT.txt ****0000006304**** AXNT20 KNHC 061752 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1815 UTC Mon Apr 6 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.

This front will gradually move southeastward and strengthen for through Wed, then stall from 31N65W to near the northwest Bahamas Wed evening through Thu night. A strong 1030 mb high pressure behind the front will cause NE fresh to strong winds currently off northeastern and central Florida to near 70W, to increase to between near-gale to gale-force by Tue morning. Seas under these winds will also build and reach 14 to 17 ft. As the stalled front weakens, winds behind it should decrease to between strong and near-gale by late Wed night. Seas will also steadily subside Thu through Thu night. Please read the latest High Seas and Offshore Waters Forecasts issued by the National Hurricane Center at website: https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml and https://www.nhc.noaa.gov/marine/offshores.php for more information. ...MONSOON TROUGH/ITCZ... A monsoon trough enters the Atlantic along the coast of Guinea near Conakry, then reaches westward to 09N19W. Farther south, an ITCZ extends westward from 01N20W to near the Amazon River Delta area. No significant convection is seen near the monsoon trough. Widely scattered moderate convection is evident up to 155 nm along either side of the ITCZ. ...GULF OF AMERICA... A stationary front extends southwestward from just off Tampa, Florida to a 1013 mb low near 24N94W, then curves southward as a cold front to beyond Veracruz, Mexico. Scattered showers and isolated thunderstorms are occurring north of the stationary front across the entier northern Gulf. Scattered showers are found near and west of the cold across the west-central and southwestern Gulf, including the western Bay of Campeche. Fresh to strong NW to NE winds with seas of 7 to 10 ft exist behind the stationary and cold front. In addition, winds near Tampico and Veracruz, Mexico are peaking at near gale-force. South and east of the fronts, gentle NE to E winds with 3 to 6 ft seas prevail. For the forecast, the stationary front will start moving southeastward as a cold front and reach from SW Florida to the eastern Bay of Campeche tonight, then drift slowly southeast of the basin Tue and Tue night. Scattered thunderstorms with locally gusty winds will accompany the front. Strong NE winds and rough seas will continue in the western Gulf behind the front tonight, then strong NE winds will develop in the northeastern basin, as low pressure develops in the Atlantic after the front exits the Gulf of America. Conditions will improve on as high pressure from the eastern U.S builds southwestward toward the northern Gulf. ...CARIBBEAN SEA... A fair and modest trade-wind regime continues across the entire Caribbean Sea. Moderate to fresh E to SE trades with seas of 5 to 7 ft are present at the central and eastern basin. Gentle to moderate NNE to ENE winds and 2 to 4 ft seas prevail for the rest of the Caribbean Sea. For the forecast, the pressure gradient between high pressure to the north and low pressure north of Colombia will maintain moderate to fresh winds at the central and eastern through Wed. By Wed night, stronger high pressure building south toward the region will increase winds to between fresh and strong mainly east of 72W. ...ATLANTIC OCEAN... See Special Features section at the very beginning about an upcoming Gale Warning. An upper-level trough extends southwestward from northeast of Bermuda across 31N61W to the central Bahamas. A cold front stretches southwestward from off the Carolinas coast across 31N78W to beyond central Florida. Scattered showers and isolated thunderstorms are noted behind this front. Coupling with convergent southeasterly trade winds, scattered moderate convection is found from 21N to 25N between 60W and 70W. In the east Atlantic, another cold front reaches southwestward from northwest of Medeira across 30N30W to near 29N43W. Scattered showers are seen up to 50 nm along either side of the front. Refer to the Monsoon Trough/ITCZ section for additional convection in the Atlantic Basin. Fresh to strong NW to NE winds and seas of 5 to 7 ft are seen off Georgia and northeastern Florida behind the first cold front. Fresh NE to ENE winds with 10 to 14 ft seas in large N swell exist behind the second cold front in the east Atlantic. Gentle winds and seas at 6 to 8 ft are seen north of 29N between 43W and the first cold front. For the remainder of the Atlantic west of 35W, moderate to fresh NE to E trades and 6 to 8 ft seas in moderate to large N to NE swell exist. For the forecast west of 55W, the first cold front will move slowly southeastward and reach from 31N72W to South Florida by Tue, then stall from Bermuda to the Florida Straits Wed. Low pressure is forecast to form along the front in the vicinity of the Bahamas on Tue, then accelerate northeastward along the boundary and out of the basin toward Bermuda by Wed. As the pressure gradient increases behind this low and strong high pressure building into the southeastern U.S., already strong NE winds north and west of the front will increase further, with gales developing Tue afternoon offshore NE Florida, then spreading east between the Bahamas and Bermuda Tue night into Wed. Very rough seas in excess of 15 kt are likely in the area of gales. With the frontal boundary remaining nearly stationary late this week, conditions will be slow to improve. $$ Chan ########################### END OF MESSAGE SET ############################ --------------------------------------------------------------------------- Message File: T_AXNT20KNHC062109_C_KWBC_20260406211015_38666572-650-TWDAT.txt ****0000007066**** AXNT20 KNHC 062109 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0015 UTC Tue Apr 7 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.
