The following information is based on satellite imagery, weather observations, radar and meteorological analysis. Based on 0600 UTC surface analysis and satellite imagery through 0930 UTC. ...Special Features... ...Gulf of Mexico Gale Warning... A cold front will enter the NW Gulf this afternoon, with strong N winds and building seas expected as it moves SE through the Gulf. Gales are forecast to develop Thu afternoon and continuing through Thu evening for waters offshore Veracruz, Mexico. As high pressure settles into the Bay of Campeche Fri morning, conditions will improve. Seas of 8 to 11 ft are possible in the gale warning area. Please, read the latest NWS High Seas Forecast issued by the National Hurricane Center at the website... https://www.nhc.noaa.gov/text/MIAHSFAT2.shtml, for more details. ...MONSOON TROUGH/ITCZ... The monsoon trough passes through the coastal plains of Sierra Leone near 08N13W to 02N17W. The ITCZ then continues from 02N17W to 00N22W, extending along the Equator to near the coast of Brazil at 44W. Scattered moderate convection is noted from the equator to 04N between 26W and 50W. GULF OF MEXICO... Please see Special Features section above for information on a Gale Warning in effect for areas offshore Veracruz, Mexico. With a 1000 mb low pressure centered near Tampico, Mexico, fresh to strong S winds are being pulled northward through much of the Gulf, with the highest winds just N of the Yucatan Peninsula. Seas are generally 4 to 6 ft, locally higher just N of the Yucatan Peninsula, with some 2 to 4 ft seas in the SW Gulf. The southerly wind flow is bringing warm moist air northward, and when this environment reaches the cooler shelf waters of the northern Gulf, fog has developed. Dense fog, with visibility below 1 mile, is being reported within 60 to 90 miles of the Texas coast. No significant convection is occurring in the Gulf of Mexico this morning. Patchy fog will persist in the northern Gulf into tonight. Fresh to locally strong S winds in the south-central Gulf will diminish tonight. A cold front will move off the Texas coast this afternoon. Strong N winds and building seas will follow the front, which will reach from the Florida Big Bend to the central Bay of Campeche by Thu morning. Gales will develop Thu afternoon offshore Veracruz, Mexico, and continue through the evening. The cold front will move SE and exit the basin by Fri morning. High pressure will move E across the northern Gulf Fri through the weekend. CARIBBEAN SEA... The gradient between low pressure over Colombia and high pressure north of the area is maintaining moderate to fresh mainly SE winds across the basin. Strong winds are occurring offshore Colombia and in the Gulf of Honduras. Seas are 4 to 6 ft in the Caribbean, except 6 to 8 ft in the aforementioned areas of strong winds. With generally dry area aloft, no significant convection is occurring this morning. For the forecast, high pressure north of the area will support fresh to strong winds in the south-central Caribbean near the coast of Colombia into tonight. Fresh to strong winds in the Gulf of Honduras will continue into Thu. Moderate to fresh winds will prevail elsewhere. A cold front will reach the Yucatan Channel by Fri morning, then move through the NW Caribbean this weekend. ATLANTIC OCEAN... The overnight squall line offshore NE Florida has diminished early this morning, although numerous moderate to isolated strong convection remains N of 28N between 72W and 78W. Outside of thunderstorm activity in this zone, strong southerly winds prevail. Elsewhere for areas W of 70W, moderate to fresh S winds dominate. Seas W of 70W average 4 to 6 ft, although 6 to 8 ft seas are affecting the areas experiencing strong winds, and 1 to 3 ft seas are present in the shallow waters surrounding the Bahamas. To the E of 70W, for areas N of 23N, high pressure is the dominate weather features, although two high centered are separated by a weak cold front extending from W of the Azores to around 28N60W. Convection along this boundary is confined to areas N of 28N. Winds are gentle to moderate in the areas influenced by the high pressure. Farther S in the Tropical Atlantic, moderate to fresh trades prevail. Seas for most areas W of 70W are 5 to 7 ft, although a zone of 8 to 10 ft seas in decaying NE swell extends from 17N to 26N E of 40W. For the forecast west of 55W, fresh to strong S winds offshore N Florida should generally continue into Thu night, before a cold front moves offshore the SE U.S. This front will reach from 31N72W through the central Bahamas and central Cuba Fri night. Strong NW winds will develop offshore N Florida behind the front this weekend. $$ KONARIK
