000 AXNT20 KNHC 080549 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 205 AM EDT Mon Jul 8 2019 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. ...TROPICAL WAVES... An Atlantic Ocean tropical wave is along 24W/25W from 16N southward. The tropical wave is moving through the Cabo Verde Islands. Widely scattered moderate to isolated strong rainshowers are from 06N to 08N between 22W and 26W. Broken to overcast multilayered clouds and other possible rainshowers cover the area that is from 08N to 19N between 20w and 30W. An Atlantic Ocean tropical wave is along 34W from 13N southward. Isolated moderate to locally strong rainshowers are from 13N southward between 30W and 42W. An Atlantic Ocean tropical wave is along 53W/54W from 15N southward. Isolated moderate to locally strong rainshowers are from 06N to 11N between 50W and 56W. A Caribbean Sea tropical wave is along 61W/62W from 20N southward. Isolated moderate to locally strong rainshowers are from 20N southward between 60W and 63w. A Caribbean Sea tropical wave is along 83W/84W, from 17N southward. The tropical wave is passing through Honduras, Nicaragua, and Costa Rica. Broad upper level cyclonic wind flow is along the western coast of Central America. Numerous strong rainshowers are in W and SW Honduras, and in the southern half of Costa Rica. The monsoon trough is along 09N/10N between 74W in Colombia and 86W in the eastern Pacific Ocean. Scattered moderate to isolated strong rainshowers are in the Gulf of Honduras, from 18N southward from 84W westward. ...MONSOON TROUGH/ITCZ... The monsoon trough passes through the coastal areas of Mauritania near 19N16W, to 11N20W, 08N30W, and 06N36W. The ITCZ continues from 06N36W to 04N45W, to the NE coast of French Guiana. Scattered moderate to isolated strong rainshowers cover the coastal plains and coastal waters of Africa from Liberia to Senegal, from 06N to 15N between 10W and 16W. Rainshowers are possible elsewhere, from 13N southward from 60W eastward, not counting any precipitation that is related to the tropical waves. GULF OF MEXICO... Broad upper level anticyclonic wind flow spans the entire Gulf of Mexico. Upper level anticyclonic wind flow covers much of the Gulf of Mexico. The only area that does not have the upper level anticyclonic wind flow is in the westernmost part of the Gulf of Mexico. An upper level trough passes through the Deep South of Texas to the coastal waters of Mexico, toward southern Mexico between the Isthmus of Tehuantepec and 100W. Isolated moderate rainshowers are in the coastal waters of Florida, from the Florida Panhandle southward. Broad surface low pressure is inland, in the SE U.S.A. A surface trough reaches the NE corner of the Gulf waters. Rainshowers are possible elsewhere from 90W eastward. Weak high pressure will dominate the basin into mid week. Low pressure is expected to develop in the NE basin on Wednesday. The area of low pressure will intensify gradually through Thursday, and generate strong to near gale-force winds for the NE waters. More intensification is possible later on Thursday, along with gale-force winds and building seas. CARIBBEAN SEA... Broad upper level cyclonic wind flow covers the areas from the Yucatan Peninsula to Guatemala. An upper level trough passes through the Windward Passage, westward and northwestward, to the Caribbean Sea coastal waters of NW Cuba. Isolated moderate rainshowers are in the area of the upper level trough. Upper level anticyclonic wind flow covers much of the rest of the Caribbean Sea, except for an upper level trough that runs from Puerto Rico to the coast of Venezuela along 65W. Broad upper level cyclonic wind flow is along the western coast of Central America. Numerous strong rainshowers are in W and SW Honduras, and in the southern half of Costa Rica. The monsoon trough is along 09N/10N between 74W in Colombia and 86W in the eastern Pacific Ocean. The 83W/84W tropical wave also is in the area. High pressure to the north of the area will support fresh to strong trade winds in the south central Caribbean Sea during the entire period. A tropical wave will move across the Lesser Antilles on Tuesday, with strong winds affecting mainly the Windward Islands. Rainshowers and thunderstorms that are associated with this wave will affect the SE part of the basin through Wednesday. It is possible that a low pressure center may develop on Friday in the Costa Rica adjacent waters, generating strong winds off the coast of Nicaragua. ATLANTIC OCEAN... Broad surface low pressure in the SE U.S.A. is drawing moisture toward Florida and the Bahamas and the NW part of the Atlantic Ocean. Broken to overcast multilayered clouds and isolated moderate to locally strong rainshowers are from Cuba northward from 74W westward. A stationary front is along 32N38W 28N45W 28N53W. Isolated moderate rainshowers are within 60 nm on either side of the line that passes through 32N35W 29N42W 29N45W 27N52W 27N60W. High pressure across the region will support gentle to moderate breezes during the entire period, except for the NW waters where moderate to fresh southerly winds are expected.
