000 AXNT20 KNHC 022301 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0005 UTC Sun Apr 3 2022 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 1800 UTC surface analysis and satellite imagery through 2255 UTC. ...SPECIAL FEATURES... East Atlantic Gale Warning: A 1001 mb low pressure SW of the Azores near 36N28W and associated cold front extending from the low center to 27N36W will move eastward through early next week. Strong to near gale-force winds are occurring N of 27N and between 24W and 38W. Meteo-France expects near gale to gale force NW winds in the IRVING region through 03/1200 UTC. Winds will diminish late Sun as the system weakens. Seas will build to 20 ft in NW swell in the area of highest winds. Seas 8 ft and greater are currently found north of a line from 31N24W to 23N35W to 31N45W. Seas will diminish late Mon. Please read the latest High Seas Forecast issued by Meteo-France at the website: http://weather.gmdss.org/II.html, for more details. ...MONSOON TROUGH/ITCZ... The monsoon trough extends from the coast of Sierra Leone near 08N13W to 04N22W. The ITCZ then continues from 04N22W to 02S33W to 00N40W to 01S49W. Scattered moderate to isolated strong convection is noted from 00N to 10N and E of 24W. Satellite- derived wind data suggest that the heaviest storm may be capable of producing strong to near gale-force wind gusts. Scattered moderate convection is found S of 05N and between 27W and 40W. GULF OF MEXICO... A stationary front extends from the Space Coast of Florida to a low pressure of 1013 mb near 28N87W to northern Tamaulipas near 26N97W. Strong thunderstorms, gusty winds and frequent lightning are occurring N of 26N and E of 89W. Elsewhere in the Gulf, clear to mostly sunny skies prevail. South of the frontal system in the eastern Gulf, moderate to locally fresh SW winds are prevalent along the periphery of the subtropical ridge. South of the frontal boundary in the western Gulf, including the Bay of Campeche, winds are light. North of the frontal boundaries, NE winds are gentle to moderate, increasing to fresh in the northeast Gulf. Seas are 3-5 ft across the basin, except 1-3 ft in the Bay of Campeche. For the forecast, the aforementioned stationary front will meander over the basin for the remainder of the weekend before dissipating early next week. Southerly flow will return through the basin after the boundary dissipates. CARIBBEAN SEA... High pressure dominates the Caribbean Sea maintaining fairly tranquil weather conditions. Moderate to fresh trades are found in the central Caribbean and Gulf of Honduras, while moderate or weaker easterly breezes are present elsewhere. Seas are 5-8 ft across the eastern and central Caribbean, peaking at 8 ft in the offshore waters of NW Colombia. Seas are 2-5 ft in the western Caribbean. For the forecast, high pressure north of the area will support fresh to strong winds in the south-central Caribbean near the coast of Colombia into Sun. Fresh to strong winds in the Gulf of Honduras will diminish tonight. Moderate to fresh winds will prevail elsewhere. ATLANTIC OCEAN... Please read the SPECIAL FEATURES section above for details on an East Atlantic Gale Warning. A cold front enters the tropical Atlantic near 31N67W to 29N77W, where it transitions into a stationary front to the Space Coast of Florida. Scattered moderate to strong convection is noted N of 27N and W of 70W. Heavy downpours, gusty winds and frequent lightning is associated with the thunderstorms near the coast of NE Florida. Elsewhere W of 60W, the weather conditions are fairly tranquil with moderate to locally fresh anticyclonic winds and seas across the region at 3-6 ft. The rest of the tropical Atlantic is dominated by a subtropical ridge of 1022 mb located near 28N48W allowing for tranquil weather conditions outside of the deep tropics. A dissipating cold front extends from 31N22W to 19N53W. No significant convection is noted with these features at this time. Moderate to occasionally fresh NE-E breezes are present behind the frontal boundary, along with seas of 8-10 ft. Just south of the dissipating front, moderate to fresh trades are present S of 20N and W of 37W due to the pressure gradient between the high pressure and lower pressures in the deep tropics. Seas are 6-8 ft. Elsewhere, moderate or weaker winds and seas of 4-7 ft prevail. For the forecast W of 65W, a cold front from near 31N68W to northern Florida will slowly dissipate this weekend. A second cold front will move across the northern waters Sun through early next week. $$ DELGADO
