####018004086#### AXNT20 KNHC 222229 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0015 UTC Tue Apr 22 2025 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 1800 UTC surface analysis and satellite imagery through 2200 UTC. ...SPECIAL FEATURES... East Atlantic Gale Warning: Meteo-France has issued a Gale Warning along with rough to very rough seas for their AGADIR Marine Zone through 23/0600 UTC. Please see the latest HIGH SEAS FORECAST and WARNING issued by Meteo-France at website: https://wwmiws.wmo.int for more information. ...MONSOON TROUGH/ITCZ... The monsoon trough axis enters the Atlantic along the coast of Guinea near 10N15W, and continues southwestward to 04N20W, where it transitions to the ITCZ south of the Equator reaching to near the coast of Brazil at 02S43W. Scattered moderate to isolated strong convection is seen from 00N-03N between 21W-24W. ...GULF OF AMERICA... High pressure ridging extends along the N Gulf promoting gentle to moderate SE winds this afternoon with seas 3-5 ft. No significant deep convection is occurring today. For the forecast, the high pressure centered NE of the area will bring mainly moderate SE winds and relatively tranquil marine conditions to the northern half of the basin through the week. The southern Gulf will experience fresh east to southeast winds, pulsing to strong off the NW Yucatan Peninsula each night as a diurnal trough affects the waters. A similar pattern should prevail over the weekend. ...CARIBBEAN SEA... The pressure gradient between the Bermuda High north of the area to a 1010 mb Colombian low is forcing fresh to strong trades over the S Central Caribbean and over the Windward Passage. A surface trough just east of the Lesser Antilles is causing the trades to only be gentle over the E Caribbean. Seas are 7-9 ft over the SW Caribbean and 4-6 ft elsewhere. No significant deep convection is occurring this afternoon over the Caribbean. For the forecast, the high pressure north of the basin will support pulsing fresh to strong NE winds across the central and western Caribbean through tonight. The high will then shift eastward which will loosen the pressure gradient and diminish winds Wed afternoon through late week. Moderate northerly swell impacting the Mona passage will gradually subside through tonight. Moderate winds and slight to moderate seas will then prevail over the weekend. ...ATLANTIC OCEAN... Please see the Special Features section above for information on a Gale Warning issued in the far eastern Atlantic. A 1010 mb surface low near 24N60W is situated along a north- south oriented surface trough along 60W. Additionally, a dissipating stationary front is situation north of the low from 27N69W to 31N54W. A tight pressure gradient between the low and a 1025 mb Bermuda High centered near 37N60W is causing fresh to strong winds and seas 8-10 ft from 25N-31N between 55W-67W. Scattered moderate convection is located from 25N-28N between 53W-60W. Elsewhere west of 20W, the trades are gentle to moderate. The seas from 18N-25N east of 32N are 8-9 ft in mixed NE wind waves and N swell. Elsewhere seas are 5-7 ft in mixed swell. For the forecast west of 55W, a pressure gradient between the surface trough and the subtropical ridge along 35N will continue to support fresh to strong E to NE winds and rough seas over Atlantic waters E of 70W and N of 23N through Wed. The trough will gradually weaken later this week as it moves slowly westward, loosening the pressure gradient and leading to improving marine conditions for the end of the week. $$ Landsea/Hagen
