000 AXNT20 KNHC 141045 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 1205 UTC Fri Jan 14 2022 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 1030 UTC. ...SPECIAL FEATURES... Atlantic Gale Warning: A broad area of low pressure located to the NE of the Bahamas will combine with low pressure moving off the Mid-Atlantic coast tonight. Explosive cyclogenesis is then expected through today as the system moves northeast toward the Canadian Maritimes. A cold front extending from the low pressure center will cross the subtropical waters of the SW N Atlantic today. Near gale-force westerly winds and rough seas will build today covering the area north of 27N between 58W and the coast of Florida, with areas of sustained gale force winds expected near and ahead of the frontal boundary. Winds will quickly decrease Sat while seas gradually abate through the weekend. A second strong cold front is forecast to emerge off the coast of Florida on Sun. Strong to gale-force winds are expected on either side of the front on Sun and Sun night north of 27N. Please read the latest NWS High Seas Forecast issued by the National Hurricane Center at website https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml for more details. Gulf of Mexico Gale Warning: A strong cold front associated with a very potent area of low pressure is forecast to move across the far NW Gulf Sat morning, then across the rest of the basin through Sun afternoon. A Gale Warning is now in effect for most of the western and northern Gulf waters for Sat and Sat night. Gale conditions are possible over some areas of the north-central and NE Gulf late Sat night into early Sun. Strong to near gale force winds will follow this front with gale force winds developing along the E Mexico offshore waters Sat and Sat night. Please read the latest NWS High Seas Forecast issued by the National Hurricane Center at website https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml for more details. Gale Warning E of 35W: A low pressure of 1009 mb is centered near 29N26W with an occlusion wrapping around to the east. An earlier scatterometer pass revealed an area of gale force winds behind the occlusion near 28N24W. This low has been cut off from the jet stream and is expected to remain in the east Atlantic for several days with strong winds possible throughout the weekend.

The monsoon trough extends from the coast of Guinea to 04N21W where the ITCZ continues through 04N33W to 02N42W. Scattered moderate convection is noted within 105 nm either side of the monsoon trough/ITCZ. GULF OF MEXICO... A Gale Warning is in effect for the Gulf of Mexico. Please see the Special Features section above for details. High pressure dominates the western half of the Gulf with light to gentle variable winds. The pressure gradient tightens in the eastern basin with winds increasing to moderate northerly in the central Gulf and fresh northwesterly in the eastern Gulf. Seas are mainly slight, building to moderate in the eastern Gulf. For the forecast, moderate to fresh NW winds over the eastern half of the Gulf will continue through this morning. Southerly moderate to fresh winds are forecast to begin tonight across the western half of the basin ahead of a strong cold front forecast to enter the Gulf region by Sat morning. Strong to near gale force northerly winds will follow the front, increasing to gale-force along the eastern Mexico offshore waters Sat and Sat night. Gale force winds are briefly forecast for the NW and north-central Gulf Sat night. The front will move E of the area early Sun afternoon. CARIBBEAN SEA... A low pressure and associated cold front extending to the southern Bahamas is supporting NW moderate winds in the NW Caribbean with 3-5 ft seas. Due to the weaker pressure gradient, trade winds are gentle to locally moderate elsewhere with seas in the 1-3 ft range. For the forecast, moderate NW winds in the NW Caribbean will diminish this evening. Gentle to moderate trade winds elsewhere will increase to moderate to fresh Sat night and prevail through Tue night. Fresh winds in the south-central Caribbean will increase to locally strong at night along Colombia and in the Gulf of Venezuela through Mon. Otherwise, a cold front is forecast to enter the NW Caribbean on Sun morning followed by NW fresh to strong winds and building seas. The front will extend from central Cuba to NE Honduras by Mon morning where it will start to weaken before dissipating Mon night. ATLANTIC OCEAN... A Gale Warning is in effect for the Atlantic waters north of 27N between 58W-65W. Please see the Special Features section above for details. A cold front extends from a 1000 mb low located near 29N67W SW to the southern Bahamas. Gale force winds are ongoing east of the low and over the north-central offshore waters associated with a reinforcing cold front entering the region. For the forecast west of 65W, near gale to gale force winds and building seas across the waters N of 27N will continue today and diminish tonight. Marine conditions will briefly improve on Sat ahead of a cold front forecast to emerge off the coast of Florida on Sun. Strong winds will start affecting the NW offshore waters Sat night, rapidly increasing to gale force winds Sun morning. Near gale to gale force winds will affect the waters N of 27N through Mon morning. In the central Atlantic, a stationary boundary extends from 31N40W to 27N54W. North of this feature, fresh to strong easterly winds and seas of 9-12 ft persist. In the eastern Atlantic, a low pressure system near 29N26W is causing gale force winds. Refer to the Gale Warning East of 35W in the special features section above for details. Elsewhere, winds are gentle to moderate with moderate seas. $$ Ramos
