DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 800 PM EDT (0000 UTC), the well-defined eye of Hurricane Matthew was located near latitude 13.5 North, longitude 72.0 West. Matthew is moving south of due west near 9 mph (15 km/h). A westward motion at a slower forward speed is expected tonight and Saturday. A turn toward the west-northwest is forecast by Saturday night, followed by a turn toward the northwest on Sunday. On the forecast track, the center of Matthew will move north of the Guajira Peninsula tonight, move across the central Caribbean Sea on Saturday, and be near Jamaica late on Sunday. Data from an Air Force Hurricane Hunter aircraft indicate that maximum sustained winds have increased to 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 this weekend, but Matthew is expected to remain a powerful hurricane through Sunday. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 195 miles (315 km) primarily to the north of the center. The latest minimum central pressure just reported by an Air Force reconnaissance aircraft was 945 mb (27.90 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected to continue in portions of the warning area in Colombia through tonight. Hurricane conditions are possible on Jamaica on Monday, with tropical storm conditions possible by late Sunday. Tropical storm conditions are possible in the watch area in Haiti by late Sunday. RAINFALL: Rainfall totals of 2 to 4 inches with isolated higher amounts are expected over Aruba, Bonaire and Curacao through Saturday. Rainfall totals of 2 to 4 inches with isolated higher amounts are expected along the coast of Colombia from the Venezuelan border to Riohacha. Rainfall totals of 1 to 2 inches with isolated higher amounts are expected along the coast of Venezuela from Coro to the Colombian border. Rainfall totals of 10 to 15 inches with isolated maximum amounts of 25 inches are expected across Jamaica and southern and southwestern Haiti. These rains may produce life-threatening flash flooding and mud slides. SURF: Swells generated by Matthew are expected to affect portions of the coasts of Puerto Rico, Hispaniola, Jamaica, Aruba, Bonaire, Curacao, Venezuela, and Colombia 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.
