2pm UPDATE: Matthew in SE, Central Bahamas Tuesday night, Wednesday


Five Day cone. (WeatherUnderground).
At 200 PM EDT, the eye of Hurricane Matthew was located near latitude 15.9 North, longitude 74.8 West. Matthew is moving toward the north near 6 mph (9 km/h), and this general motion is forecast to continue through Wednesday with an increase in forward speed expected tonight. On the forecast track, the center of Matthew will approach southwestern Haiti tonight, move near eastern Cuba late Tuesday, and move near or over portions of the southeastern and central Bahamas Tuesday night and Wednesday.

Data from an Air Force Reserve Hurricane Hunter aircraft indicate
that maximum sustained winds are near 140 mph (220 km/h) with higher
gusts.  Matthew is a dangerous 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 Wednesday.

Hurricane-force winds extend outward up to 35 miles (55 km) from
the center and tropical-storm-force winds extend outward up to 185
miles (295 km).

The latest minimum central pressure based on data from the aircraft
is 940 mb (27.76 inches).

HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are expected to first reach Haiti tonight, eastern Cuba Tuesday, and the southeastern Bahamas late Tuesday. Tropical storm conditions are expected to first reach Haiti this afternoon, eastern Cuba tonight, and the southeastern Bahamas early Tuesday, making outside preparations difficult or dangerous. Preparations to protect life and property should be rushed to completion. Tropical storm conditions are expected in Jamaica and along the southern coast of the Dominican Republic within the warning area beginning today. 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 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...5 to 10 inches, isolated 15 to 20 inches Southeastern Bahamas...8 to 12 inches, isolated 15 inches Turks and Caicos Islands...2 to 5 inches, isolated 8 inches Northeastern Haiti and the Dominican Republic...1 to 3 inches, isolated 5 inches Western Jamaica...1 to 2 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 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. 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.
