000 AXNT20 KNHC 140547 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 147 AM EDT FRI OCT 14 2016 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 0530 UTC. ...SPECIAL FEATURES... Hurricane Nicole is centered near 34.4N 61.2W at 14/0300 UTC or 222 nm northeast of Bermuda moving east-northeast at 18 kt. Estimated minimum central pressure is 967 mb. Maximum sustained wind speed is 85 kt with gusts to 105 kt. Scattered moderate convection is north of 32N between 55W-64W. See the latest NHC Intermediate Public Advisory under AWIPS/WMO headers MIATCPAT5/WTNT35 KNHC and the full NHC Forecast/Advisory under AWIPS/WMO headers MIATCMAT5/WTNT25 KNHC for more details. ...TROPICAL WAVES... A tropical wave is in the Tropical Atlantic extends its axis from 17N42W to 09N42W, moving west near 15 kt over the past 24 hours. The wave coincides with a well defined 700 mb trough between 37W-45W and is embedded within a surge of moisture. No significant convection is related to this wave at this time. A tropical wave is in the eastern Caribbean with axis extending from 16N69W to 09N69W, moving west 10 to 15 kt over the past 24 hours. The wave coincides with a broad 700 mb trough between 68W-73W and is embedded within an area of abundant moisture. However, no associated deep convection is noted with this wave at this time. ...ITCZ/MONSOON TROUGH... The Monsoon Trough extends across Africa into the east Tropical Atlantic near 12N16W to 07N21W to 07N32W. Scattered moderate convection is from 04N-09N between 20W-30W. ...DISCUSSION... ...GULF OF MEXICO... A surface ridge extends across the basin anchored by a 1020 mb high centered near 30N88W. A surface trough extends over the Bay of Campeche from 21N96W to 19N96W with isolated showers. To the south; an upper level trough extends from the west Atlantic across the southern Gulf waters supporting cloudiness and isolated showers south of 24N. Scatterometer data depicts moderate to fresh easterly winds across the basin. The surface trough will meander across the west and southwest Gulf as the surface ridge persists through the weekend. ...CARIBBEAN SEA... A tropical wave is moving across the southeast Caribbean waters. Please refer to the section above for details. A surface trough extends from southern Cuba near 20N77W to 11N80W. This feature combined with the Monsoon Trough that extends from 76W-83W and a diffluent flow aloft support cloudiness and isolated convection between 71W-84W. Scatterometer data depicts gentle to moderate trades across the basin. The surface trough and the tropical wave will continue moving westward and merge into a broad area of low pressure in the southwest Caribbean this weekend. ...HISPANIOLA... A diffluent flow aloft is supporting isolated convection across the island. This activity will dissipate overnight. Similar activity is expected to develop each afternoon through the weekend. ...ATLANTIC OCEAN... The primary concern this evening continues to be Hurricane Nicole which is moving east-northeast away from Bermuda. See the Special Features above for details. A tropical wave is moving across the central Atlantic. Please refer to the section above for details. A surface trough extends across the west Atlantic from 22N78W to 25N69W. Isolated convection is observed in the vicinity of this boundary. A 1018 mb surface high is centered near 28N50W. A surface trough extends east of the Lesser Antilles from 18N54W to 11N56W with isolated convection. To the east, a 1014 mb surface low is centered near 30N40W, with surface trough extending from the low to 27N46W. A 1021 surface high is centered over the eastern Atlantic near 27N27W. Hurricane Nicole is expected to continue moving east-northeast with an increase in forward speed through the next 24 hours. Little change is expected elsewhere.
