DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 800 AM EDT (1200 UTC), the center of Hurricane Matthew was located near latitude 14.1 North, longitude 74.3 West. Matthew is moving toward the northwest near 5 mph (7 km/h). This general motion is expected to continue today, followed by a turn toward the north tonight. On the forecast track, the center of Matthew will approach southwestern Haiti and Jamaica on Monday. Maximum sustained winds are near 150 mph (240 km/h) with higher gusts. Matthew is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some fluctuations in intensity are possible during the next couple of days, but Matthew is expected to remain a powerful hurricane through Monday night. Hurricane-force winds extend outward up to 25 miles (35 km) from the center, and tropical-storm-force winds extend outward up to 205 miles (335 km). The minimum central pressure reported by an Air Force Reserve Hurricane Hunter aircraft is 947 mb (27.96 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are expected to reach Jamaica and Haiti on Monday, and eastern Cuba Monday night. Tropical storm conditions are expected to first reach Jamaica and Haiti this evening, and eastern Cuba early Monday, making outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion. Tropical storm conditions are expected along the southern coast of the Dominican Republic within the warning area by tonight. Hurricane conditions are possible in the hurricane watch areas by late Tuesday with tropical storm conditions possible by early Tuesday. Tropical storm conditions are also possible in the tropical storm watch area in the Dominican Republic by late Monday. RAINFALL: Matthew is expected to produce total rain accumulations of 15 to 25 inches over southern Haiti, with possible isolated maximum amounts of 40 inches. Matthew is expected to produce total rain accumulations of 10 to 20 inches over eastern Jamaica, the Dominican Republic and eastern Cuba, with possible isolated maximum amounts of 25 inches. This rainfall will produce life-threatening flash floods and mud slides. Matthew is expected to produce additional rain accumulations of 1 to 2 inches over Aruba, Curacao, and Bonaire through today. Matthew is expected to produce total rain accumulations of 2 to 4 inches over northern Colombia, northwest Venezuela, and western Jamaica, with possible isolated maximum amounts of 6 inches. STORM SURGE: The combination of a dangerous storm surge and large and destructive waves could raise water levels by as much as the following amounts above normal tide levels... Southern Coast of Cuba east of Cabo Cruz...7 to 11 feet South Coast of Haiti...6 to 9 feet Northern Coast of Cuba east of Camaguey...4 to 6 feet Jamaica...3 to 5 feet Gulf of Gonave in Haiti...3 to 5 feet Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. Large waves generated by Matthew will cause water rises to occur well in advance of and well away from the track of the center. SURF: Swells generated by Matthew will continue to affect portions of the coasts of Puerto Rico, Hispaniola, Jamaica, Aruba, Bonaire, Curacao, Venezuela, Colombia, eastern Cuba, and the Caribbean coastline of Central America during the next few days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
