DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 500 AM EDT (0900 UTC), the center of Hurricane Matthew was located near latitude 17.8 North, longitude 74.4 West. Matthew is moving toward the north near 9 mph (15 km/h) and this general motion is expected to continue today. A turn toward the north-northwest is expected by Wednesday, followed by a northwest turn Wednesday night. On the forecast track, the center of Matthew will pass near or over southwestern Haiti during the next few hours, move near eastern Cuba later today, and move near or over portions of the southeastern and central Bahamas tonight and Wednesday, and approach the northwestern Bahamas Wednesday night Maximum sustained winds are near 145 mph (230 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 at least Wednesday night. Hurricane-force winds extend outward up to 40 miles (65 km) from the center and tropical-storm-force winds extend outward up to 185 miles (295 km). The estimated minimum central pressure is 934 mb (27.58 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are beginning to reach the southwestern portion of Haiti and will spread northward today. Hurricane conditions are expected to reach eastern Cuba later today, the southeastern Bahamas Tuesday evening, the central Bahamas on Wednesday, and the northwestern Bahamas Wednesday night. Tropical storm conditions are expected to continue spreading across Haiti today, eastern Cuba later this morning, the southeastern Bahamas later today, and the central and northwestern Bahamas Tuesday night and Wednesday, making outside preparations difficult or dangerous. Tropical storm conditions are expected in portions of Jamaica and along the southern coast of the Dominican Republic within the warning area today, and will spread northward into the Turks and Caicos Islands tonight. Hurricane conditions are possible in the hurricane watch areas in Cuba tonight with tropical storm conditions possible later today. RAINFALL: Matthew is expected to produce total rainfall amounts in the following areas: Southern Haiti and southwestern Dominican Republic...15 to 25 inches, isolated 40 inches Eastern Cuba and northwestern Haiti...8 to 12 inches, isolated 20 inches Eastern Jamaica...4 to 6 inches, isolated 10 inches The Bahamas...8 to 12 inches, isolated 15 inches Turks and Caicos Islands...2 to 5 inches, isolated 8 inches Northeastern Haiti and the Northern Dominican Republic...1 to 3 inches, isolated 5 inches Western Jamaica...1 to 2 inches, isolated 3 inches Life-threatening flash floods and mudslides are likely from this rainfall in southern and northwestern Haiti, the southwestern Dominican Republic, and eastern Cuba. 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...2 to 4 feet Gulf of Gonave in Haiti...3 to 5 feet Southern coast of the Dominican Republic...1 to 3 feet The 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, eastern Cuba, and the Caribbean coastline of Central America during the next few days. Swells from Matthew will begin affecting portions of the Bahamas on Tuesday. These swells are likely to cause life- threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 800 AM EDT. Next complete advisory at 1100 AM EDT. $$ Forecaster Brown/Cangialosi |
