991 AXNT20 KNHC 141053 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1215 UTC Fri Feb 14 2025 Tropical Weather Discussion for North America, Central America Gulf of Mexico, 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 1030 UTC. ...SPECIAL FEATURES... Caribbean Gale Warning: Widespread fresh E trade winds and rough seas will occur across the southwestern, central and eastern Caribbean through this weekend as a strong pressure gradient prevails between low pressure over northwestern Colombia and high pressure in the central Atlantic. Winds will pulse to gale force early this morning offshore of NW Colombia, with winds reaching near-gale force each night and early morning thereafter into Sun. Very rough seas will occur near and to the west of the highest winds. Gulf of Mexico Gale Warning: A mixed cold and stationary front extending from central Florida to 24N95W to the western Bay of Campeche will stall today. Strong to near-gale force winds will occur to the north and west of this front early this morning, and winds will briefly reach gale force offshore of Veracruz. Very rough seas up to 15 ft will occur near the gale force winds. Winds and seas in this region will diminish from north to south this morning. ...MONSOON TROUGH/ITCZ... The monsoon trough enters the Atlantic near 05N09W and extends to 01S18W. The ITCZ continues from 01S18W to 01S37W. Scattered moderate convection is occurring south of 06N and east of 15W, and south of 04N and west of 30W. ...GULF of Mexico... Please refer to the special features section for information regarding a Gale Warning in the southwestern Gulf of Mexico this morning. A cold front has been analyzed from Tampa Bay to 27N86W, and a stationary front continues to 24N95W to the western Bay of Campeche. Fresh to strong NE to E winds and rough seas are occurring to the north of these fronts in the northern Gulf of Mexico. Strong to near-gale force N winds are occurring in the far southwestern Gulf, with gale force winds noted just offshore of Veracruz. Rough seas are occurring to the west of the stationary front, with locally very rough seas of 12 to 15 ft noted near the gale force winds. Elsewhere, a trough has been analyzed in the eastern Bay of Campeche, and moderate to locally fresh SE to NE winds are noted surrounding this feature. Otherwise, moderate to locally fresh N winds prevail in the southeastern Gulf. For the forecast, the aforementioned cold and stationary fronts will stall today. Strong to near-gale force winds will occur to the north and west of this front early this morning, and winds will briefly reach gale force offshore of Veracruz. Very rough seas up to 15 ft will occur near the gale force winds. Winds and seas in this region will diminish from north to south this morning. The aforementioned front will lift northward this afternoon into Sat, supporting moderate to fresh S to SE winds across much of the basin. Winds will increase to strong speeds across the northwestern and north-central Gulf of Mexico by Sat morning as a tightening pressure gradient develops between the front and strengthening low pressure in the central United States. Looking ahead, the next cold front will enter the northwestern basin late Sat into Sun, promoting fresh to strong N winds and rough seas west of 90W. Gale force winds will be possible offshore of Veracruz on Sun behind the front. ...CARIBBEAN SEA... Please refer to the special features section for information regarding a Gale Warning in the south-central Caribbean offshore of Colombia this morning. A tight pressure gradient prevails between high pressure in the central Atlantic and the eastern extent of the Pacific monsoon trough in the south-central Caribbean. This pattern is supporting widespread fresh E winds through much of the basin, with strong winds occurring in the central Caribbean, through the Windward Passage, in the Gulf of Honduras and through the Atlantic Passages into the northeastern Caribbean. Gale force winds are noted just offshore of Colombia. Rough seas cover the southwestern, central and eastern basin, with locally very rough seas occurring near and to the west of the gale force winds. For the forecast, widespread fresh E trade winds and rough seas will occur across the southwestern, central and eastern Caribbean through this weekend. Winds will pulse to gale force early this morning offshore of NW Colombia, with winds reaching near-gale force each night and early morning thereafter into Sun. Very rough seas will occur near and to the west of the highest winds. Pulsing strong winds are expected across the central Caribbean through this weekend, as well as in the Gulf of Venezuela, through the Atlantic Passages, in the lee of Cuba and Hispaniola, and in the Gulf of Honduras. Otherwise, moderate to fresh winds will occur in the northwestern Caribbean through this weekend. Looking ahead, a decreasing pressure gradient between the Colombian low and high pressure in the western and central Atlantic will support moderate to fresh trade winds and locally rough seas across the basin into early next week, with locally strong winds occurring offshore of Colombia. ...ATLANTIC OCEAN... A cold front extends from 31N21W to 25.5N33W in the eastern Atlantic. Rough seas are occurring along and to the north of this front, and seas of 12 to 15 ft are noted north of 27.5N. Elsewhere, a cold front is pushing off the southeastern coast of the United States, extending from 31N77W to central Florida. Moderate N winds are occurring north of this front. Otherwise, the remainder of the basin is dominated by a 1030 mb high centered near 29N57W. Moderate to fresh E trade winds and rough are occurring south of 25N, with locally strong winds noted south of 20N and west of 40W. Locally very rough seas are occurring near the strongest winds. For the forecast, fresh to strong E trade winds are expected south of 25N, including through the Atlantic Passages into the Caribbean through late tonight, with fresh to pulsing strong E winds expected into early next week. A long-period E swell will support rough seas in this region, with locally very rough seas possible east of the Windward Islands through Sat. A strong cold front extending from 31N77W to central Florida will progress southeastward today, leading to fresh to strong NE to E winds behind the front, generally north of 28.5N and west of 60W. Rough seas will occur in tandem with these winds. The cold front will stall along 28N on Sat, and moderate to fresh NE to E winds will prevail north of this boundary. Looking ahead, fresh to strong S to SW winds and rough seas will develop west of 70W off the coast of Florida on Sun ahead of a very strong storm system moving through the eastern United States. A cold front associated with this system will exit the SE United States late Sun and reach from Bermuda to the Florida Straits by Mon afternoon, then drift SE and weaken considerably through Tue. $$ ADAMS --- SBBSecho 3.20-Linux * Origin: capitolcityonline.net * Telnet/SSH:2022/HTTP (618:250/1) |
