DISCUSSION AND OUTLOOK ---------------------- At 500 AM AST (0900 UTC), the eye of Hurricane Beryl was located near latitude 11.7 North, longitude 59.9 West. Beryl is moving toward the west near 20 mph (31 km/h). A continued quick westward to west-northwestward motion is expected during the next few days. On the forecast track, the center of Beryl is expected to move across the Windward Islands this morning and across the southeastern and central Caribbean Sea late today through Wednesday. Maximum sustained winds remain near 120 mph (195 km/h) with higher gusts. Beryl is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Fluctuations in strength are likely during the next day or so, but Beryl is expected to remain an extremely dangerous major hurricane as its core moves through the Windward Islands into the eastern Caribbean. Some weakening is expected in the central Caribbean by midweek, though Beryl is forecast to remain a hurricane. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 125 miles (205 km). Grantley Adams International Airport on Barbados recently reported sustained winds of 45 mph (72 km/h) with a gust to 60 mph (96 km/h). The estimated minimum central pressure is 965 mb (28.50 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Beryl can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC. WIND: Hurricane conditions are expected in the hurricane warning area beginning early this morning. Potentially catastrophic wind damage is expected where the core of Beryl moves through portions of the Windward Islands, with the highest risk of the core in St. Vincent and the Grenadines, and Grenada. Wind speeds atop and on the windward sides of hills and mountains are often up to 30 percent stronger than the near-surface winds indicated in this advisory, and in some elevated locations could be even greater. Tropical storm conditions are expected in the tropical storm warning area starting soon, making outside preparations difficult or dangerous. Tropical storm conditions are possible within the watch area starting this morning for Dominica, and by Tuesday afternoon for parts of the southern coast of Hispaniola. STORM SURGE: A life-threatening storm surge will raise water levels by as much as 6 to 9 feet above normal tide levels in areas of onshore winds near where the eye makes landfall in the hurricane warning area. Near the coast, the surge will be accompanied by large and destructive waves. RAINFALL: Hurricane Beryl is expected to produce rainfall totals of 3 to 6 inches across Barbados and the Windward Islands through this afternoon. Localized maxima of 10 inches are possible, especially in the Grenadines and Grenada. This rainfall may cause flash flooding in vulnerable areas. For a complete depiction of forecast rainfall and flash flooding associated with Hurricane Beryl, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at2.shtml?rainqpf SURF: Large swells generated by Beryl are expected across 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 in the next day or so. These swells are expected to cause life-threatening surf and rip current conditions.
