A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours.

DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 500 AM EDT (0900 UTC), the center of Hurricane Matthew was located near latitude 15.2 North, longitude 74.9 West. Matthew is moving toward the north near 6 mph (9 km/h). A general northward motion with some increase in forward speed is expected through Tuesday. On the forecast track, the center of Matthew will approach Jamaica and southwestern Haiti tonight, and eastern Cuba on Tuesday. Maximum sustained winds are near 130 mph (215 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 Tuesday. Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 195 miles (315 km). The estimated minimum central pressure based on reports from NOAA buoy 42058 is 943 mb (27.85 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are expected to reach Jamaica and Haiti tonight, and eastern Cuba Tuesday. Tropical storm conditions are expected to first reach Jamaica and Haiti later today and eastern Cuba tonight, 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 beginning today. Tropical storm conditions are expected to reach the southeastern Bahamas early Tuesday with hurricane conditions expected by late Tuesday. Hurricane conditions are possible in the hurricane watch areas by Tuesday night with tropical storm conditions possible on Tuesday. Tropical storm conditions are also possible in the tropical storm watch area in the Dominican Republic by late today. RAINFALL: Matthew is expected to produce total rain accumulations of 15 to 25 inches across southern Haiti and the southwestern portion of the Dominican Republic, with possible isolated amounts of 40 inches. Across eastern Cuba and western Haiti, total rain accumulations of 8 to 12 inches are expected with possible isolated maximum amounts of 20 inches. Across eastern Jamaica, total rainfall of 5 to 10 inches is expected, with isolated maximum amounts of 15 inches possible. This rainfall will likely produce life-threatening flash floods and mudslides. Matthew is expected to produce total rain accumulations of 8 to 12 inches over the southeastern Bahamas, with isolated maximum amounts of 15 inches. Matthew is expected to produce total rain accumulations of 2 to 5 inches, with isolated maximum amounts of 8 inches over the Turks and Caicos Islands. Lower amounts are expected across the northeastern section of Haiti and the Dominican Republic, with amounts ranging from 1 to 3 inches with isolated amounts around 5 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...7 to 10 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 Southern coast of the Dominican Republic...1 to 3 feet Central and southeastern Bahamas...10 to 15 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 Hispaniola, Jamaica, Aruba, 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.
