000 AXNT20 KNHC 070000 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0005 UTC Sun May 7 2023 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 2350 UTC. ...SPECIAL FEATURES... East Atlantic Gale Warning: The marine forecast from the Meteo-France consists of a warning for northerly gale-force winds, in the marine zone AGADIR, from 06/1500 UTC until 07/1200 UTC. Please, refer to the Meteo-France High Seas Forecast, that is on the website, https://wwmiws.wmo.int, for details. ...MONSOON TROUGH/ITCZ... The monsoon trough passes extends from the coast of Guinea to 05N18W. The ITCZ continues from 05N18W to 05N30W to 02N50W. Scattered moderate convection is from 01N to 08N between 20W and 46W. ...GULF OF MEXICO... High pressure of 1025 mb anchored over South Carolina extends a ridge SW across the Gulf of Mexico and provides gentle to moderate E to SE winds N of 23N. Fresh to strong NE to E winds are along the coast and adjacent waters of the Yucatan Peninsula being supported by a thermal trough. Winds are moderate to locally fresh from the E across the remainder SW Gulf. Seas are 1 to 3 ft basin-wide. Otherwise, upper level diffluent flow support scattered showers and thunderstorms in the offshore waters between SE Louisiana and the Florida Panhandle. For the forecast, fresh to locally strong winds will pulse near and to the NW of the Yucatan Peninsula each night into the early morning hours through Thu night due to local effects related to a thermal trough. Otherwise, high pressure will dominate the Gulf waters through the forecast period producing gentle to moderate winds and slight to moderate seas, with the exception of moderate to fresh SE to S winds over the western Gulf. ...CARIBBEAN SEA... Surface ridging N of the area extends into the northern half of the Caribbean and along low pressure in NW Colombia continue to support fresh to strong trade winds across the SE, south-central and portions of the SW basin. Seas within this area of strong winds range between 7 to 9 ft. Fresh NE winds are in the Gulf of Honduras with seas to 3 ft while the remainder NW basin enjoys a light breeze. Moderate trade winds dominate the remainder Caribbean with seas in the 3 to 6 ft range. For the forecast, the pressure difference between high pressure N of the area and lower pressure in NW Colombian will support fresh to strong trade winds in the south-central Caribbean, including the Gulf of Venezuela, through early next week. Moderate to fresh E winds are expected in the Gulf of Honduras through Wed. These winds will begin to pulse to fresh to strong at night starting Wed night. Elsewhere, gentle to moderate winds will prevail. ...ATLANTIC OCEAN... See the Special Features above for information on an ongoing Gale Warning for the region of Agadir, Africa. A surface trough extends across the north-central Bahamas and support an area of fresh to strong E winds to the N and NE of the trough. A cold front extends from 31N45W SW to near 26N55W where it stalls and continue to near the Turks and Caicos Islands. NW swell associated with this front is producing seas to 9 ft N of 27N between 38W and 58W. The remainder central and eastern subtropical Atlantic is under the influence of the ridge of the Azores High. Latest scatterometter data show fresh to strong N to NE winds between the coast of NW Africa and both the Canary and Cape verde Islands. Altimeter data show seas of 8 to 10 ft in the aforementioned region. Otherwise, moderate to fresh NE to E winds and seas to 8 ft dominate the tropical Atlantic waters. For the forecast W of 55W, the surface trough across the north- central Bahamas will drift west-southward through Sun. The area of fresh to strong E winds to the N and NE of the trough will shift southward from the Bahamas to waters adjacent South Florida tonight through late Sun. The stationary front will transition to a cold front tonight into Sun while weakening. The NW swell over the far NE part of the area will shift out of the region by late tonight. High pressure will build over the western Atlantic in the wake of the front through the early part of the upcoming week allowing for winds to diminish to gentle to moderate speeds. A backdoor cold front may approach the waters offshore NE Florida Wed through Thu night, followed by moderate E winds. $$ Ramos
