****0000006595**** AXNT20 KNHC 261633 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1815 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 1200 UTC surface analysis and satellite imagery through 1633 UTC. ...SPECIAL FEATURES... Caribbean Gale Warning: The pressure gradient between strong high pressure of 1032 mb centered over 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 along the coast of Colombia tonight through 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 01N19W. The ITCZ extends from 01N19W to near 01S44W. Widely scattered moderate convection can be found from 00N to 05N east 29W. ...GULF OF MEXICO... High pressure of 1032 mb located over Savannah, Georgia extends a ridge across the SE of the United States into the Gulf region while low pressure of 1022 mb is located over 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 93W, 4 to 6 ft in the central Gulf between 86W and 93W, 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 today. A weak front will move into the NW Gulf late tonight into early Mon. It will stall and dissipate over the NW Gulf coastal waters through Mon night. Mostly gentle to moderate winds will continue over the basin through Tue before increasing to moderate to fresh speeds at mid-week as the pressure gradient tightens, then increasing further to fresh to locally strong speeds by the end of the week. Slight to moderate seas are expected throughout the basin into midweek, thereafter, seas will build over the western Gulf under increasing southerly flow. ...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 NE Caribbean. Seas are 7 to 12 ft in the south-central Caribbean spreading into the SW Caribbean in NE to E swell, with 5 to 7 ft elsewhere. A weak surface trough is analyzed over the Gulf of Honduras. Isolated showers are depicted along this trough. Patches of low level clouds, embedded in the trade wind flow, are moving across the eastern Caribbean, producing isolated to scattered passing showers. For the forecast, fresh to strong trade winds over the majority of the basin will change little today and tonight, then begin to decrease in coverage on Mon, being more confined to the central Caribbean waters by midweek. Winds will pulse to minimal gale- force just offshore northern Colombia tonight into early Mon morning. 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 extends from 31N48W to 28N58W is stalling to eastern Cuba near 21.5N77W. The front is followed by fresh to strong northeast winds and rough seas immediately behind it, with gentle to moderate winds and subsiding seas offshore northern Florida and NE of the Bahamas. 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 1029 mb high pressure situated near 28N34W 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 22N. Seas are 8 to 10 ft within these winds. Gentle to moderate anticyclonic winds prevail across the waters north of 22N 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 7 to 9 ft in long period NW swell east of about 30W to the Canary and Madeira Islands. For the forecast west of 55W, fresh to strong east winds south of 25N west of 73W, and also south of 23N east of 73W will begin to diminish this afternoon. Seas over these waters will subside through Mon. A stationary front extending from near 29N55W to 26N66W and to eastern Cuba will start to weaken today. Otherwise, fairly tranquil marine conditions will prevail 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 31N68W to the NW Bahamas Thu. $$ KRV
