The following information is based on satellite imagery, weather observations, radar and meteorological analysis. Based on 0600 UTC surface analysis and satellite imagery through 0720 UTC. ...SPECIAL FEATURES... Hurricane Beryl is centered near 14.6N 66.9W at 02/0900 UTC or 320 nm SE of Isla Beata Dominican Republic, moving WNW at 19 kt. Estimated minimum central pressure is 935 mb. Maximum sustained wind speed is 145 kt with gusts to 175 kt. Peak seas are currently around 43 ft. Numerous strong convection is noted within 90 nm of the center. Numerous moderate to strong convection is noted in a band between 90 nm and 240 nm in the E semicircle. Scattered to numerous moderate convection is elsewhere within 150 nm in the W semicircle. Beryl is forecast to continue moving rapidly west-northwestward during the next couple of days and turn westward by Thursday. On the forecast track, the center of Beryl will move quickly across the southeastern and central Caribbean Sea today and is forecast to pass near Jamaica on Wednesday and the Cayman Islands on Thursday. Interests in Belize, the Yucatan Peninsula, Cuba, and the southwestern Gulf of Mexico should monitor the progress of Beryl. Additional watches and warnings will likely be required later today or Wednesday. Beryl is a category 5 hurricane on the Saffir-Simpson Hurricane Wind Scale. Weakening should begin later today, but Beryl is still expected to be near major hurricane intensity as its moves into the central Caribbean and passes near Jamaica on Wednesday and the Cayman Islands on Thursday. Additional weakening is expected thereafter, though Beryl is forecast to remain a hurricane in the northwestern Caribbean. Heavy rainfall and flash flooding are likely over much of Jamaica on Wednesday. Large swells generated by Beryl will continue across the Windward and southern Leeward Islands during the next couple of days. Swells are also expected to reach the southern coasts of Puerto Rico and Hispaniola later today. These swells are expected to cause life-threatening surf and rip current conditions.

A tropical wave is in the eastern Atlantic along 20W, south of 18N, and moving westward at around 10 kt. Scattered moderate isolated strong convection is noted from 05N to 14N between the coast of Africa and 30W. A central Atlantic tropical wave (Invest 96L) is along 44.5W, south of 17N, moving westward at 15 to 20 kt. Isolated to widely scattered moderate convection is noted from 09N to 12N between 44.5W and 48.5W. Associated winds are currently 20 to 25 kt with seas of 7 to 10 ft. Environmental conditions are only marginally conducive for additional development of this system while it moves generally westward at 15 to 20 kt across the central and western tropical Atlantic. Interests in the Lesser Antilles should still monitor the progress of this system, with heavy rainfall possible midweek. This system has a low chance of development in the next 48 hours and 7 days. Please refer to the latest NHC Tropical Weather Outlook at www.hurricanes.gov for more details. A western Caribbean tropical wave is along 81W, south of 20N, moving westward at around 10 kt. Scattered moderate to isolated strong convection is present in the SW Caribbean from 09N to 13N between 76W and 83.5W, and from 13N to 20N between the tropical wave axis and 87W. ...MONSOON TROUGH/ITCZ... The monsoon trough reaches the Atlantic through the coast of Mauritania near 18N16W and continues southwestward to 09N35W to 11N44W to 06N55W. For details on convection, please read the Tropical Waves section. ...GULF OF MEXICO... Please read the Special Features section on the latest details on Major Hurricane Beryl over the Eastern Caribbean which may impact the Gulf of Mexico by the end of the week and weekend. An expansive subtropical ridge centered west of the Azores extends southwestward to the Gulf of Mexico. The weak pressure gradient across the basin result in moderate or weaker winds and slight to moderate seas. A few storms currently in the southern Bay of Campeche developed yesterday evening over the western Yucatan. Elsewhere, fairly tranquil weather conditions prevail. For the forecast, a ridge across the northern Gulf will linger through Thu in advance of Hurricane Beryl now in the eastern Caribbean. Major Hurricane Beryl is near 14.6N 66.9W at 5 AM EDT, and is moving west-northwest at 19 kt. Maximum sustained winds are 145 kt with gusts to 175 kt, and the minimum central pressure is 935 mb. Beryl will move to 15.5N 69.6W this afternoon, 16.5N 73.4W Wed morning, 17.4N 76.8W Wed afternoon, 18.2N 80.2W Thu morning, 18.7N 83.6W Thu afternoon, and 19.3N 86.7W Fri morning. Beryl will weaken to a tropical storm over 21.2N 91.8W early Sat. Meanwhile, moderate seas in the western Gulf due to dissipated Chris will subside through early today. ...CARIBBEAN SEA... Please read the Special Features section on the latest details on Major Hurricane Beryl over the Eastern Caribbean. Please read the Tropical Waves section for details on associated convection. Outside of the influence of Beryl, fresh to strong easterly trade winds are evident in the central Caribbean Sea, with the strongest winds occurring off NW Colombia and south of Hispaniola. Seas in these waters are 6 to 8 ft. Moderate or weaker winds and slight to moderate seas are prevalent. For the forecast, Major Hurricane Beryl is south of the area near 14.6N 66.9W at 5 AM EDT, and is moving west-northwest at 19 kt. Maximum sustained winds are 145 kt with gusts to 175 kt, and the minimum central pressure is 935 mb. Beryl will continue to move WNW and across the Caribbean through late Thu, and inland across the Yucatan Peninsula Thu night, remaining south of the area. Otherwise, central Atlantic high pressure will extend a ridge southwestward to N Florida to support gentle to moderate winds and slight to moderate seas north of 25N, with moderate to fresh trades and mainly moderate seas south of 25N. Winds and seas will be locally strong north of Puerto Rico and Hispaniola through the next several days as Beryl moves through the Caribbean. A decaying cold front may drop south of 31N tonight through Wed night, potentially stalling and lingering near 30N through the end of the week. ...ATLANTIC OCEAN... Please read the Special Features section on the latest details on Major Hurricane Beryl over the Eastern Caribbean. Please read the Tropical Waves section for details on Invest 96L. An expansive 1033 mb high pressure system centered west of the Azores near 39.5N38W dominates the tropical Atlantic. An upper level low near 32N56W supports scattered moderate convection north of 29N between 53W and 58W. Similar convection is noted near the central Bahamas and northeast of the NW Bahamas, as well as NE of the Leeward Islands. Moderate to fresh trades and 6 to 9 ft seas are south of 22N and west of 40W outside of the influence of Invest 96L. Gentle to moderate winds and slight to moderate seas are north of 22N and west of 30W. Fresh to strong NE winds are between the coast of Africa and the Canary Islands, continuing southwestward to the Cabo Verde Islands. Seas are 6 to 9 ft in this area. Gentle to moderate wins and 5 to 7 ft seas prevail across the remainder of the waters. For the forecast west of 55W, Major Hurricane Beryl is south of the area near 14.6N 66.9W at 5 AM EDT, and is moving west- northwest at 19 kt.
