Subj : TROPDISC: Gale Warnings To : All From : Dumas Walker Date : Tue Mar 04 2025 06:54 pm 343 AXNT20 KNHC 042043 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL Issued by NWS Ocean Prediction Center Washington DC 0015 UTC Wed Mar 5 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 1800 UTC surface analysis and satellite imagery through 2040 UTC. ....SPECIAL FEATURES... Gulf of Mexico Gale Warning: A cold front has entered the NW Gulf. Fresh to strong southerly winds, with frequent gusts to gale force, and rough seas are noted ahead of the front, mainly N of 24N and W of 90W. The front will reach from the Florida Big Bend to the central Bay of Campeche by Wed morning, and move SE of area by Wed night. Frequent gusts to gale force may also occur in the SW Gulf, near the Veracruz area, late tonight into Wed morning. Atlantic Gale Warning: Widespread strong to near-gale force S winds and rough seas will be possible north of 27N and west of 75W tonight through Wed ahead of a cold front that is forecast to move off the southeastern coast of the United States on Wed. Localized gale force winds and very rough seas will be possible N of 29N on either side of the front through Thu. N swell behind the front will propagate southeastward through late week, with very rough seas spreading to north of 25N through Thu, and north of 22N through Fri. ....MONSOON TROUGH/ITCZ... The monsoon trough enters the Atlantic near 05N09W and extends to 01N17W. The ITCZ continues from 01N17W to 03S38W. Scattered moderate to isolated strong convection is observed from 05S to 03N between 12W and 39W. GULF OF MEXICO... Please see the Special Features section for information on an ongoing Gale Warning. A cold front is over the far NW Gulf. A 1029 mb high is centered near 36N70W, with associated ridge extending southwestward into the eastern Gulf. Aside from the gale force gusts, the pressure gradient between these features is supporting fresh to strong winds winds across much of the Gulf, reaching near gale force W of 90W. Seas of 8 to 11 ft are noted over the NW Gulf, with seas in the 5-7 ft range elsewhere. For the forecast, the front will reach from the Florida Big Bend to the central Bay of Campeche by Wed morning, and move SE of area by Wed night. Fresh to strong northerly winds and moderate to rough seas will occur in the wake of the front, mainly offshore of the US Gulf coast, and offshore of Veracruz. Frequent gusts to gale force may also occur in the SW Gulf, near the Veracruz area, late tonight into Wed morning. Then, fresh to strong NW winds will persist over the NE Gulf Wed through Thu morning. On Thu, high pressure will be in control of the weather pattern across the Gulf region supporting moderate to locally fresh E to SE winds across the basin. The high pressure will move eastward toward N Florida on Fri producing moderate to fresh SE to S winds over the western Gulf. Another cold front is forecast to enter the NW Gulf by Sat night. Gale conditions are possible offshore Veracruz on Sun. CARIBBEAN SEA... A 1029 mb high is centered near 36N70W. The pressure gradient between this area of high pressure and the Colombian low is supporting fresh to locally strong winds, and seas of 4-7 ft, over the south central Caribbean. Gentle to moderate winds, and seas of 3-5 ft, prevail elsewhere. For the forecast, high pressure north of area combined with the Colombian low will lead to pulsing fresh to locally strong NE to E winds through the Gulf of Venezuela and offshore of Colombia this week, with the strongest winds occurring each night and morning. Moderate to fresh NE winds are expected through early Wed across the Windward Passage and downwind of Cuba as the pressure gradient strengthens between a cold front in the central Atlantic, high pressure offshore of the eastern United States, and the Colombian low. Fresh to locally strong SE winds will be possible this evening into Wed in the Gulf of Honduras. Otherwise, moderate trade winds and slight to moderate seas are expected across the central and eastern Caribbean this week. A cold front will reach the NW Caribbean by Wed night, and extends from central Cuba to near Chetumal, Mexico by Thu morning, and from eastern Cuba to northern Belize by Thu night while weakening. ATLANTIC OCEAN... Please see the Special Features section for information on a Gale Warning off the coast of NE Florida. A stationary front extends from 27N55W to 22N70W. The pressure gradient between the front and high pressure just offshore of the eastern United States supports a belt of fresh to strong NE to E winds N of the front to about 27N, including the NW and central Bahamas. Seas over these waters are in the 7-10 ft range. Farther east, a 1025 mb high is centered near 35N31W, with associated ridge extending SW to near 25N50W. Gentle to locally moderate winds are in the vicinity of the ridge, with moderate to fresh winds, and seas of 5-8 ft, prevailing elsewhere. For the forecast W of 55W, the next cold front is forecast to move off the southeastern coast of the United States on Wed. Gale force winds and very rough seas are expected on either side of the front and N of 29N through Thu. The front will reach from 31N74W to western Cuba by Wed night, and from 31N63W to eastern Cuba Thu night. N swell behind the front will propagate southeastward through late week, building seas to 18 or or 19 ft north of 25N through Thu, and north of 22N through Fri. Otherwise, moderate to fresh trades and rough seas will prevail south of 25N this week. $$ AL --- SBBSecho 3.20-Linux * Origin: capitolcityonline.net * Telnet/SSH:2022/HTTP (21:1/175) .
