DISCUSSION AND OUTLOOK ---------------------- At 1100 AM AST (1500 UTC), the eye of Hurricane Beryl was located near latitude 12.4 North, longitude 61.3 West. Beryl is moving toward the west-northwest near 20 mph (31 km/h). The eyewall of Beryl is moving across the southern Windward Islands. This is an extremely dangerous and life-threatening situation. Take action now to protect your life! Residents in Grenada, the Grenadine Islands, and Carriacou Island should not leave their shelter as winds will rapidly increase within the eyewall of Beryl. Remain in place through the passage of these life-threatening conditions and do not venture out in the eye of the storm. Beryl is expected to move quickly westward to west-northwestward during the next few days. On the forecast track, the center of Beryl is currently moving across the southern Windward Islands and will move across the southeastern and central Caribbean Sea late today through Wednesday. Maximum sustained winds are near 140 mph (220 km/h) with higher gusts. Beryl is a category 4 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 40 miles (65 km) from the center and tropical-storm-force winds extend outward up to 125 miles (205 km). A weather station in Crown Point, Tobago recently reported sustained winds of 46 mph (74 km/h) with a gust to 54 mph (87 km/h). There have been multiple reports of downed trees, flooded streets, power outages and storm surge flooding in the Grenandines, Grenada, Barbados, and Tobago. The minimum central pressure based on aircraft data is 956 mb (28.23 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 occurring in the hurricane warning area. Potentially catastrophic wind damage is expected where the core of Beryl is moving through portions of the southern Windward Islands, including Carriacou Island, Grenada, and the Grenadine Islands. 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. Hurricane conditions are possible in Jamaica by Wednesday. Tropical storm conditions are occurring or imminent in the tropical storm warning area. Tropical storm conditions are possible within the watch area 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, Tobago, 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 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 in the next day or so. These swells are expected to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 200 PM AST. Next complete advisory at 500 PM AST. $$ Forecaster Reinhart
