000 AXNT20 KNHC 020604 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 0605 UTC Wed Dec 02 2020 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 32N. The following information is based on satellite imagery, weather observations, radar and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0520 UTC. ...MONSOON TROUGH/ITCZ... The monsoon trough passes through the northern coastal sections of Sierra Leone near 08N13W, to 07N17W. The ITCZ continues from 07N17W, to 05N22W, 07N32W, and to 06N48W. Precipitation: widely scattered moderate to isolated strong is within 420 nm to the north of the ITCZ between 20W and 40W. Isolated moderate is elsewhere from 15N southward from 43W eastward. GULF OF MEXICO... Broad upper level SW wind flow spans the Gulf of Mexico. Broad surface anticyclonic wind flow covers the Gulf of Mexico. As high pressure slides east, strong SE return flow will set up Wed morning in the NW Gulf and continue through Wed night as a cold front moves off the TX coast. This front will move into the central Gulf Thu, bringing gale conditions to the extreme SW Gulf offshore Veracruz, Mexico. The cold front will move into the eastern Gulf Fri, and move SE of the Gulf by late Sat. CARIBBEAN SEA... Broad upper level anticyclonic wind flow covers the Caribbean Sea. A cold front passes through SE Cuba to 19N79W. The front becomes stationary, from 19N79W, and curving southwestward to the central coast of Honduras. Broken to overcast multilayered clouds and possible rainshowers are to the north and nortwest of the frontal boundary, and within 210 nm to the south and southeast of the frontal boundary. The monsoon trough is along 09N/11N from 73W in N Colombia, beyond Costa Rica. Precipitation: widely scattered moderate to isolated strong is to the south of the line that runs from the central coast of southern Hispaniola to the NE coast of Nicaragua, from 70W westward. Moderate to fresh tradewinds will continue across much of the basin nto Wed night. A cold front has stalled this evening from eastern Cuba to the eastern Gulf of Honduras and will gradually dissipate through late Thu. Fresh to strong winds and building seas will prevail NW of this front through Thu. Winds will increase to fresh to strong across central portions late Wed into Thu night as high pres behind the front shifts into the W Atlc. Looking ahead, another cold front may enter the Yucatan Channel by late Sat. ATLANTIC OCEAN... A cold front passes through 32N, about 180 nm to the west of Bermuda, to 27N70W, to the Bahamas from 22N to 23N, cutting across SE Cuba, to 19N79W. Broken to overcast multilayered clouds, and possible rainshowers, are within 300 nm to the east and southeast of the cold front, and within 200 nm to the west and northwest of the cold front. Broad upper level cyclonic wind flow covers the Atlantic Ocean from 20N northward between 40W and 60W. One surface trough is along 23N52W 19N55W. A second surface trough is along 34N51W 24N48W. A third surface trough is from 360 nm to 480 nm to the west of the second surface trough. Precipitation: widely scattered moderate to isolated strong is from 19N northward between 40W and 53W. Rainshowers are possible also from 18N northward between 53W and 66W. A 1005 mb low pressure center is near 34N22W. Gale-force winds are in the METEO-FRANCE area that is called ACORES. Precipitation: isolated moderate is within 400 nm of the center in the southern semicircle. The non-tropical low pressure center is between the Madeira Islands and the Azores. This system has become less organized during the past 24 hours. Environmental conditions are expected to become less conducive for development, as the system moves southwestward during the next day or two. Development into a subtropical cyclone now is unlikely. Expect strong winds and locally heavy rains in the Madeira Islands and the Azores, through Wednesday. Please, read the METEO-FRANCE high seas forecast, at the following webpage: http://www.gmdss.org/II.html, for more details. The current Atlantic Ocean cold front stretches from just E of Bermuda to the Turks and Caicos islands to eastern Cuba. This front will drift SE and stall through late week. Strong NW winds and building seas will prevail behind the front, mainly N of 28N and W of 70W tonight, with strong winds developing over waters adjacent to Cuba and the SE Bahamas Wed into Thu. Looking ahead, another cold front will move off the coast of northeast Florida Sat. $$ mt/sk
