000 AXNT20 KNHC 030552 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0605 UTC Wed Jan 3 2024 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 0000 UTC surface analysis and satellite imagery through 0500 UTC. ...SPECIAL FEATURES... A cold front curves southwestward from 31N63W to the Florida Straits. Scattered showers are occurring ahead of the front. Strong to gale force W to NW winds are behind the front north of 28N with seas in the 8 to 14 ft range. These winds and high seas will shift eastward along with the cold front across the western Atlantic through Wed afternoon. As the front starts to weaken at the central Atlantic Wed night, both winds and seas should gradually subside. Fresh to strong SW winds and seas to 11 ft will also continue to progress eastward with the front. Please refer to the High Seas issued by the National Hurricane Center at https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml1 more details. ...MONSOON TROUGH/ITCZ... The monsoon trough enters the Atlantic near 08N13W to 07N17W. The ITCZ runs from 07N17W to 04N30W to 05N35W. No significant convection is noted at this time. ...GULF OF MEXICO... A cold front extends from the Florida Straits to the central Gulf, where it meets a warm front extending from a 1013 mb low pressure center over the southern tip of Texas. A recent ASCAT pass found moderate to fresh southerly winds west of 90W, with locally strong winds noted offshore Texas near the low. Seas range from 4 to 6 ft in the NW Gulf north of 25N and west of 90W, and 2 to 4 ft elsewhere. A line of convection recently emerged off the south Texas coast. For the forecast, moderate to fresh NE winds will prevail north of the front. The area of low pressure will move off the coast of Texas tonight and track NE to E across the northern Gulf through Wed night. The associated warm front will shift north over the central Gulf into Wed while the low drags a cold front across the Gulf waters. Fresh to strong winds are expected with this low and cold front. Another cold front is forecast to move into the basin Fri night into the weekend, bringing similar fresh to strong winds. ...CARIBBEAN SEA... Gentle to moderate trades and seas to 3 ft are ongoing over the eastern half of the basin. A surface ridge over the Gulf of Mexico extends into the NW Caribbean, supporting moderate to fresh NE winds and seas in the 5-6 ft range over the western half of the basin, including offshore the coast of Colombia. There is no deep convection ongoing basin-wide. For the forecast, a tight pressure gradient between high pressure centered N of the basin and lower pressure over South America will support fresh to strong winds off Colombia into the weekend. S winds will increase to fresh to strong in the NW Caribbean Fri night as a cold front approaches from the Gulf of Mexico. ...ATLANTIC OCEAN... Please read the SPECIAL FEATURES section at the beginning about a Gale Warning. Outside of the gale force winds behind the cold front, moderate to fresh NW winds were captured in a recent ASCAT pass. Moderate to fresh southerly winds were captured ahead of the front, north of 27N and west of 55W. Seas are 6 to 9 ft in these areas. Elsewhere, surface ridging dominates the remainder of the central and eastern subtropical Atlantic waters. Winds are light to gentle, and seas are in the 5-6 ft over this region. Over the tropical Atlantic, winds are moderate to locally fresh, with seas to 6 ft. For the forecast W of 55W, another cold front will move off the Florida coast Wed night, extend from Bermuda to the SE Bahamas Thu night, then move over the SE waters for the end of the week. Strong winds and rough seas will again impact northern waters on both sides of this front. $$ Mora
