DISCUSSION AND OUTLOOK ---------------------- At 200 PM EDT (1800 UTC), the center of Hurricane Beryl was located near latitude 17.3 North, longitude 76.9 West. Beryl is moving toward the west-northwest near 18 mph (30 km/h), and this general motion should continue through today, followed by a turn more toward the west tonight or Thursday. On the forecast track, the center of Beryl will pass near or over Jamaica during the next several hours. After that, the center is expected to pass near or over the Cayman Islands tonight or early Thursday and move over the Yucatan Peninsula of Mexico Thursday night or early Friday. Maximum sustained winds are near 140 mph (225 km/h) with higher gusts. Beryl is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some weakening is forecast during the next day or two. However, Beryl is forecast to be at or near major hurricane intensity while it passes near Jamaica during the next several hours and the Cayman Islands tonight or early Thursday. Additional weakening is expected thereafter, though Beryl is forecast to remain a hurricane in the northwestern Caribbean. Hurricane-force winds extend outward up to 45 miles (75 km) from the center and tropical-storm-force winds extend outward up to 185 miles (295 km). The latest minimum central pressure estimated from Air Force Reserve Hurricane Hunter aircraft data is 959 mb (28.32 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 about to spread into Jamaica, especially along the southern coast and in the mountainous areas. Tropical storm conditions are spreading across Jamaica at this time, making outside preparations difficult or dangerous. 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 expected to reach the Cayman Islands tonight or early Thursday. Winds are expected to first reach tropical storm strength late this afternoon, making outside preparations difficult or dangerous. Hurricane conditions are expected in the hurricane warning area on the Yucatan Peninsula Thursday night or early Friday morning. Winds are expected to first reach tropical storm strength by late Thursday, making outside preparations difficult or dangerous. Hurricane conditions are possible in the hurricane watch area along the east coast of the Yucatan Peninsula as early as late Thursday. Tropical storm conditions are expected in the tropical storm warning area along the southwestern peninsula of Haiti today, and in the tropical storm warning area of the Yucatan Peninsula by late Thursday. Tropical storm conditions are possible in the tropical storm watch area along portions of the coast of Belize by late Thursday or early Friday, and in the tropical storm watch area along the coast of the Yucatan Peninsula by Friday or Friday night. STORM SURGE: Storm surge could raise water levels by as much as 6 to 9 feet above normal tide levels in areas of onshore winds along the immediate coast of Jamaica. Storm surge could raise water levels by as much as 2 to 4 feet above normal tide levels in areas of onshore winds along the immediate coast of the Cayman Islands. Storm surge could raise water levels by as much as 1 to 3 feet above ground level in areas of onshore winds along the southern coast of Hispaniola. Storm surge could raise water levels by as much as 3 to 5 feet above ground level in areas of onshore winds along the east coast of the Yucatan Peninsula within the hurricane warning area. Near the coast, the surge will be accompanied by large and destructive waves. RAINFALL: Beryl is expected to produce rainfall totals of 4 to 8 inches with localized amounts of 12 inches across Jamaica through this evening, along with additional rainfall of 4 to 6 inches over the Tiburon Peninsula of Haiti. This heavy rainfall is expected to cause life-threatening flash flooding and mudslides. Beryl is also expected to bring rainfall totals of 4 to 6 inches over the Cayman Islands tonight into Thursday. Over the Yucatan Peninsula into northern Belize, Beryl is expected to produce rainfall totals of 4 to 6 inches with localized amounts of 8 inches late Thursday through Friday. Scattered instances of flash flooding are anticipated.

Swells will also spread toward portions of western Cuba, the Yucatan Peninsula, and the coast of Belize during 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.
