000 AXNT20 KNHC 030004 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 804 PM EDT Fri Nov 2 2018 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 1800 UTC surface analysis and satellite imagery through 2345 UTC. ...TROPICAL WAVES... A tropical wave was repositioned on this map. Its axis extends along 25W from 01N-12N. This wave is noted in model guidance at 700 mb and TPW imagery shows high moisture content associated with it. Scattered moderate convection is present south of 10N. A tropical wave was added to this analysis, with axis along 45W from 03N-13N. This wave is also noted in model guidance at 700 mb and TPW imagery shows high moisture content associated with it. Scattered showers are noted along the wave's axis. A tropical wave extends its axis along 62W from 03N-13N, moving west at around 10-15 kts. This wave is noted in model guidance at 700 mb. TPW imagery depicts moderate to high moisture content near and east of the wave axis. Scattered showers are noted south of 10N affecting Venezuela. ...MONSOON TROUGH/ITCZ... The monsoon trough is analyzed from 09N13W to 06N20W to 07N28W. The ITCZ extends from 07N33W to 09N56W. Aside from the showers related to the two tropical waves, scattered showers are within 120 nm on the northern side of the boundary. Scattered moderate convection are noted 210 nm on either side of the monsoon trough between 10W-27W. GULF OF MEXICO... A cold front extends from 30N83W to 19N92W. An upper level trough entering the Southeast Plains is enhancing this feature. Scattered moderate to strong convection extends 210 nm southeast of the front. The front will stall from southern Florida to Cancun, Mexico tonight, then gradually dissipate on Sat as E to SE return flow develops across the basin. CARIBBEAN SEA... A broad area of high pressure centered over the west Atlantic extends across most of the basin. To the south, scattered moderate convection is observed over SW Caribbean south of 12N between 73W-84W, to the coast of Nicaragua. This convection is due to the eastern extent of the Eastern Pacific monsoon trough. The western Atlantic surface high will continue to shift eastward through the weekend and produce fresh tradewinds east of 80W, especially the south-central Caribbean through Saturday evening. These winds will be strongest at night close to the coast of Colombia. A Gulf of Mexico cold front will stall and weaken near the Yucatan Channel Sat morning. Trades will diminish Sun and Mon. ATLANTIC OCEAN... A western Atlantic 1029 mb high is centered near 35N54W. A cold front enters the central Atlantic near 31N37W and extends to 20N49W to 20N67W. Scattered showers are within 130 nm on either side of the front mainly north of 22N. An eastern Atlantic 1030 mb high is centered near 38N17W producing fair weather. The front will dissipate this weekend. Another front will enter the western Atlantic this weekend. This front is expected to weaken and stall from near 31N74W to southern Florida Sat evening then gradually shift northward on Sun.
