000 AXNT20 KNHC 301803 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1805 UTC Wed Mar 30 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 1200 UTC surface analysis and satellite imagery through 1630 UTC. ...SPECIAL FEATURES... Atlantic Gale Warning: Strong southerly winds with frequent gusts to gale force are expected off NE Florida early Thu morning through evening, ahead of the next cold front forecast to enter the western Atlantic on Fri. Wave heights of 9-11 ft are expected with these winds by Thu morning. Gulf of Mexico Gale Warning: Strong southerly flow with frequent gusts to gale force over the central Gulf today, will spread to the eastern Gulf this evening. Seas are expected to peak at 10 to 14 ft. Conditions should start to improve by late Thu morning. For more information on both warnings, please see the latest NWS High Seas Forecast issued by the National Hurricane Center at website https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml for more details. ...MONSOON TROUGH/ITCZ... A monsoon trough remains confined primarily to the African Continent. An ITCZ extends from near 02N18W through EQ30W to NW of Sao Luis, Brazil near 01N46W. Scattered moderate to isolated strong convection is noted from 04S to 03N between 24W and the NW Brazilian coast. ...GULF OF MEXICO... Refer to the Special Features section for information on a Gale Warning. A strong ridge of high pressure extends from N Florida to the N Bay of Campeche. Latest satellite scatterometer and altimetery data reveal strong to near-gale southerly winds, and seas of 8 to 12 ft across the central Gulf. Moderate to fresh S winds with seas at 8 to 10 ft are found across the W Gulf. Moderate to fresh SE winds and seas of 5 to 7 ft prevail over the E Gulf. Areas of smoke could be reducing visibilities within 90 nm of the coast of Mexico between Veracruz and the Mouth of the Rio Grande River, due to agricultural fires in Mexico. For the forecast, strong southerly flow, with frequent gusts to gale force, are expected across much of the basin north of 22N, with these hazardous marine conditions gradually diminishing and improving from W to E through tonight. A strong pressure gradient between high pressure over the western Atlantic and a deepening low pressure over Texas and NE Mexico supports these wind speeds. A cold front will approach the coast of Texas this evening, and extend from the Florida Big Bend to near Tuxpan, Mexico by Thu evening. Then, the front will become stationary while drifting northward through Sat. Southerly return flow will dominate by the end of the weekend into early next week. ...CARIBBEAN SEA... A large 1025 mb high pressure S of the Azores will continue to channel NE to ENE trade winds across the basin through early next week. Convergent trades are triggering scattered showers near the Windward Islands. A 1009 mb low is producing scattered showers and thunderstorms near the Panama-Colombia border and adjacent Caribbean waters. Fresh to strong trades and seas at 8 to 10 ft are present for the central and S central basin, N of Colombia. Moderate to fresh trades with seas at 6 to 8 ft are found over the N central and NW basin. Gentle to moderate trades with seas at 4 to 6 ft prevail for the rest of the basin. For the forecast, high pressure near the Azores will continue to promote fresh to strong winds in the south-central Caribbean near the coast of Colombia, across the Windward Passage to south of Jamaica, south of the Dominican Republic, in the lee of Cuba, and in the Gulf of Honduras through the week, diminishing in the Lee of Cuba and across the Windward passage by late tonight. Moderate to fresh winds will prevail elsewhere. Moderate to fresh trade winds along with larger trade-wind swell will persist east of the Lesser Antilles through Fri. Winds will diminish somewhat across the basin for the upcoming weekend as the high pressure weakens. ...ATLANTIC OCEAN... Refer to the Special Features section for information on a Gale Warning. A nearly stationary front extends from 31N49W across 24N60W to Hispaniola. Scattered showers are found near and up to 80nm SE, and 30nm NW of this front. Refer to the Monsoon Trough/ITCZ section for additional convection in the Atlantic Basin. Residual northerly swell with seas at 6 to 8 ft, and moderate to fresh NE winds are evident from the SE Bahamas northward, between 60W and 75W. Moderate with locally fresh NE trades and seas of 6 to 8 ft are seen from the Equator to 22N between 20W and 60W/Lesser Antilles, and also near the Canary Islands N of 22N between the NW African coast and 30W. Gentle to moderate winds with seas at 5 to 6 ft prevail for the rest of the basin. For the forecast, the aforementioned nearly stationary front will continue to support scattered showers and isolated thunderstorms as well as some gusty winds over Hispaniola and the adjacent waters likely through tonight. Fresh to strong easterly winds are forecast across the waters south of 23N to 24N through Thu. Strong southerly winds, with frequent gusts to gale force are expected off NE Florida Thu and Thu night ahead of the next cold front forecast to enter the western Atlantic on Fri. The front will move across the N waters on Sat, then stall and begin to drift northward on Sun while weakening. Fairly tranquil marine conditions are forecast for the start of next week. $$ Chan
