DISCUSSION AND 48-HOUR OUTLOOK
At 1100 PM EDT (0300 UTC), the center of Hurricane Matthew was
located near latitude 16.9 North, longitude 74.6 West. Matthew is
moving toward the north near 7 mph (11 km/h) and this general motion
is expected to continue tonight through Tuesday. A turn toward
the north-northwest is forecast on Wednesday. On the forecast
track, the center of Matthew will approach southwestern Haiti
tonight and Tuesday morning, move near eastern Cuba late Tuesday,
and move near or over portions of the southeastern and central
Bahamas Tuesday night and Wednesday.
Reports from an Air Force Reserve hurricane hunter aircraft
indicate that maximum sustained winds are near 145 mph (230 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 at
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
The estimated minimum central pressure is 934 mb (27.58 inches).
HAZARDS AFFECTING LAND
WIND: Hurricane conditions are expected to first reach Haiti
tonight, eastern Cuba Tuesday, the southeastern Bahamas late
Tuesday, and the central Bahamas on Wednesday. Tropical storm
conditions are expected to continue spreading across Haiti tonight,
eastern Cuba by early Tuesday morning, the southeastern Bahamas
early Tuesday, and the central Bahamas Tuesday night, making outside
preparations difficult or dangerous. Preparations to protect life
and property should be rushed to completion.
Tropical storm conditions are expected in portions of Jamaica and
along the southern coast of the Dominican Republic within the
warning area tonight.
Hurricane conditions are possible in the northwestern Bahamas on
Thursday, with tropical storm conditions possible on Wednesday.
Hurricane conditions are possible in the hurricane watch areas in
Cuba and the Turks and Caicos Islands by Tuesday night with tropical
storm conditions possible on Tuesday.
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
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 3 inches, isolated 6 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, 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.
