368 AXNT20 KNHC 271754 TWDAT Tropical Weather Discussion NWS National Hurricane Center Miami FL 205 PM EDT Fri Jul 26 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 1200 UTC surface analysis and satellite imagery through 1740 UTC. ...TROPICAL WAVES... An Atlantic Ocean tropical wave is along 28W/29W from 20N southward. Scattered moderate to strong rainshowers are from 08N to 10N between 28W and 30W. Isolated moderate to locally strong rainshowers cover the rest of the area that is from 05N to 12N between 23W and 33W. An Atlantic Ocean tropical wave is along 38W/39W from 20N southward. A 1012 mb low pressure center is along the wave near 14N. Isolated moderate rainshowers are from 05N to 15N between 36W and 43W. An Atlantic Ocean tropical wave is along 54W/55W from 20N southward. Scattered moderate to isolated strong rainshowers cover the area that is from 09N to 15N between 52W and 60W. A Caribbean Sea tropical wave is along 84W/85W from 20N southward. Widely scattered moderate to isolated strong rainshowers are in the coastal plains/coastal waters of Central America from eastern Honduras to Panama along 80W. ...MONSOON TROUGH/ITCZ... The monsoon trough passes through the coastal area of Guinea- Bissau near 12N16W, to 11N20W 10N30W, to the 1012 mb low pressure center near 14N that is along the 38W/39W tropical wave. The ITCZ continues from the low pressure center, to 13N50W 11N55W and 09N60W. Scattered moderate to strong rainshowers are from 07N to 11N between Africa and 16W. Isolated moderate to locally strong rainshowers are elsewhere from 02N to 12N between 07W and 21W. Isolated moderate rainshowers are from 05N to 12N between 44W and 53W. GULF OF MEXICO... An upper level trough passes through Lousiana, and it reaches the SW corner of the Gulf of Mexico. Broad surface low pressure is in the coastal plains of Louisiana and Texas. A stationary front passes through 32N74W to 30N78W, to the Florida east coast near 28N81W, and to 28N84W in the NE corner of the Gulf of Mexico. A separate surface trough is along 93W/94W from 21N southward, in the SW corner of the Gulf of Mexico. Isolated moderate to locally strong rainshowers are to the north of the line that passes through the Florida west coast near 27N, to 23N90W, and into the SW corner of the Gulf of Mexico near 22N87W. Isolated moderate rainshowers are in the Yucatan Channel. The remnants of the current eastern Gulf of Mexico stationary front continue to generate scattered rainshowers and thunderstorms in the northern half of the basin. The current SW Gulf of Mexico surface trough is supporting similar conditions in the SE Mexico adjacent waters. This trough will form in the Yucatan Peninsula each day, and then move into the SW corner of the Gulf of Mexico at night, with fresh to strong winds. A surface ridge will prevail elsewhere across the remainder of the basin during the entire period. CARIBBEAN SEA... A middle level to upper level trough cuts across the Caribbean Sea, from the northeastern corner of the area into the southwestern corner of the area. Comparatively drier air in subsidence covers the NE corner, from 14N northward from 73W eastward. Scattered moderate to isolated strong rainshowers are in the coastal plains and coastal waters of Nicaragua from 11N to 13N between 81W and 85W. A tropical wave also is along 84W/85W from 20N southward. The monsoon trough extends from 10N72W in NW Venezuela, across Colombia, beyond 08N78W near Panama, and beyond 07N81W in the eastern Pacific Ocean. Other rainshowers are in the waters that are from 16N southward from 76W westward. Rainshowers are possible, elsewhere, from 80W eastward, in areas of broken low level clouds. The pressure gradient, between high pressure to the north and lower pressure in northern Colombia, will maintain fresh to strong trade winds in most of the central and southwest Caribbean Sea through Monday, and resuming on Wednesday evening. The wind speeds are forecast to pulse to near gale-force at night, along the coast of Colombia and in the Gulf of Venezuela, from tonight through Sunday night. A tropical wave will move into the tropical Atlantic Ocean waters today, and across the Lesser Antilles on Sunday. Fresh to strong winds, and rainshowers associated with this tropical wave, will be affecting mainly the Windward Islands. ATLANTIC OCEAN... A stationary front passes through 32N74W to 30N78W, to the Florida east coast near 28N81W, and to 28N84W in the NE corner of the Gulf of Mexico. Widely scattered moderate to isolated strong rainshowers are to the NW of the line that passes through 32N69W, to the coast of Cuba near 22N77W. Broad upper level cyclonic wind flow covers the Atlantic Ocean from 20N northward between 60W and 76W. Isolated moderate rainshowers are in the area of broad upper level cyclonic wind flow. The current stationary front, that is in the NW waters, will continue to weaken through Sunday, and dissipate on Monday. Moderate to fresh NE winds will prevail N of the front through early Sunday. Light to gentle winds will dominate the region, except for the SE forecast waters, where a tighter pressure gradient will support moderate to fresh E to SE winds.
