DISCUSSION AND 48-HOUR OUTLOOK
At 200 PM EDT (1800 UTC), 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
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
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. Please consult
products from your local weather office.
