Interests elsewhere along the coasts of Venezuela and Colombia and elsewhere in Hispaniola should monitor the progress of Matthew.

DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 500 AM EDT (0900 UTC), the center of Hurricane Matthew was located near latitude 13.3 North, longitude 72.8 West. Matthew is moving toward the west near 7 mph (11 km/h). A turn toward the west-northwest is forecast later today, followed by a turn toward the north-northwest on Sunday. On the forecast track, the center of Matthew will move away from the Guajira Peninsula this morning, move across the central Caribbean Sea today, and be approaching Jamaica late Sunday. Maximum sustained winds are near 155 mph (250 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 45 miles (75 km) from the center and tropical-storm-force winds extend outward up to 205 miles (335 km). The estimated minimum central pressure is 942 mb (27.82 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected to continue in portions of the warning area in Colombia for the next few hours. 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 today. 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, Colombia, and eastern Cuba 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.
