****0000006966**** AXNT20 KNHC 260835 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1215 UTC Sun Jan 26 2025 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 0600 UTC surface analysis and satellite imagery through 0800 UTC. ...SPECIAL FEATURES... Caribbean Gale Warning: The pressure gradient between strong high pressure of 1031 mb centered near Savannah, Georgia and low pressure across NW Colombian will continue to support fresh to strong trades and rough seas across the south-central Caribbean early this week. Winds are expected to pulse to gale-force early this morning along the coast of Colombia, and then again tonight through into early Mon morning. Seas are forecast to build to 12 or 13 ft during these periods of strongest winds. Please refer to the latest NWS High Seas Forecast issued by the National Hurricane Center at the website: www.nhc.noaa.gov/text/MIAHSFAT2.shtml ...MONSOON TROUGH/ITCZ... The monsoon trough enters the Atlantic through the coast of Liberia near 06N10.5W and continues SW to near 03N19W. The ITCZ extends from 03N19W to near the coast of Brazil at 00N50W. Widely scattered moderate convection can be found from 01N to 05N between 10W and 30W. ...GULF OF MEXICO... High pressure of 1031 mb located near Savannah, Georgia extends a ridge across the SE of the United States into the Gulf region while low pressure of 1022 mb is located near the Texas Hill Country along a slow moving front. This pattern supports fresh to strong return flow in the western Gulf with moderate to locally fresh NE to E winds in the SE and south-central Gulf, including the Straits of Florida. Winds are gentle to moderate in the NE and north-central Gulf. Seas are 5 to 8 ft over the western Gulf west of 94W, 4 to 7 ft in the central Gulf between 85W and 94W, and 3 to 5 ft elsewhere, except 3 ft or less in the NE coastal waters. Lingering cold air stratocumulus clouds are noted over the central Gulf. Low level clouds, with patches of light rain are noted over the NW Gulf. For the forecast, low pressure over the Texas Hill Country and high pressure extending from near Savannah, Georgia to southern Louisiana will support fresh to strong return flow in the western Gulf with moderate to locally fresh winds in the eastern Gulf through today. A weak front will move into the NW Gulf late tonight into early Mon, stalling and dissipating over the NW Gulf coastal waters through Mon night. Mainly gentle to moderate winds will prevail across the basin for the end of the weekend through early next week, increasing to moderate to fresh mid-week as the pressure gradient tightens, then fresh to locally strong by the end of the week. Meanwhile, moderate to locally fresh seas in the SW half of the Gulf will subside by Mon, with slight to moderate seas elsewhere into the early part of the week. Seas may build back late in the week with the increasing winds. ...CARIBBEAN SEA... A Gale Warning remains in effect for the waters near the coast of Colombia through early Mon morning. Please refer to the Special Features section for more details. Aside from the strong to gale-force winds in the south-central Caribbean, fresh to strong winds dominate the majority of the remainder of the basin, including the Windward Passage, the Lee of Cuba, south of Hispaniola, and the offshore waters of Nicaragua. Seas are 7 to 11 ft in the south-central Caribbean spreading into the SW Caribbean in NE to E swell, 5 to 8 ft elsewhere west of 72W, and 4 to 6 ft east of 72W. Patches of low level clouds, embedded in the trade wind flow, are moving across the eastern Caribbean, and also extend from south of Jamaica to coastal Nicaragua, producing isolated to scattered passing showers. For the forecast, fresh to strong trade winds over the majority of the basin through the remainder of the weekend will decrease in coverage during the early part of the week, being more confined to the central part of the Caribbean basin by around midweek. Winds will pulse to minimal gale-force just offshore northern Colombia early today and again tonight. Meanwhile, long-period east swell will continue to produce rough seas through the Atlantic Passages of the Windward Islands into early part of the week. ...ATLANTIC OCEAN... A weakening cold front from 30N55W to 24.5N68W is stalling to eastern Cuba near 21.5N77W. The front is followed by fresh to strong north to northeast winds and rough seas immediately behind it, with gentle to moderate winds and subsiding seas offshore northern Florida and NE of the Bahamas under 1031 mb high pressure centered near Savannah, Georgia. A band of low level clouds, with areas of light to moderate rain, is associated with the front. Cold air stratocumulus clouds are seen behind the frontal boundary over the western Atlantic reaching parts of the E coast of Florida. East of the front, a 1027 mb high pressure situated near 28N38W dominates the remainder of the Atlantic forecast waters. A band of fresh to strong NE to E winds prevail across the southern periphery of the ridge over the Tropical Atlantic mainly south of 23N/24N. Seas are 8 to 11 ft within these winds per earlier observations. Gentle to moderate anticyclonic winds prevail across the waters north of 23N/24N under the influence of the ridge, with moderate to fresh winds across the remainder of the open Atlantic. Seas are mainly 5 to 7 ft north of 23N and east of the cold front, except 8 to 10 ft in long period NW swell east of about 37W to the Canary and Madeira Islands. For the forecast west of 55W, the front will completely stall and weaken from near 29N55W to 25N59W to the SE Bahamas later this morning. Fresh to strong northeast winds are expected at that time to be south of about 27N and west of the front. Meanwhile, fresh to strong trade winds and rough seas will remain in the open Tropical Atlantic waters south of 22N through the early part of the week with rough seas. Fairly tranquil marine conditions will prevail elsewhere for the early part of the week as weak high pressure settles in over the region. Moderate to fresh west winds along with building seas may be seen in the far northern forecast waters Tue through midweek in advance of a pair of cold fronts. The first front may remain north of the area, while the second front may reach from near 31N70W to the NW Bahamas Thu. $$ Lewitsky
