DISCUSSION AND 48-HOUR OUTLOOK
At 200 AM EDT (0600 UTC), the center of Hurricane Matthew was
located near latitude 17.4 North, longitude 74.5 West. Matthew is
moving toward the north near 8 mph (13 km/h) and this general
motion is expected to continue today. A turn toward the
north-northwest is forecast by Wednesday. On the forecast track,
the center of Matthew will pass near or over southwestern Haiti
this morning, move near eastern Cuba late today, 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 least
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 latest minimum central pressure reported by reconnaissance
aircraft was 934 mb (27.58 inches).
HAZARDS AFFECTING LAND
WIND: Hurricane conditions are expected to reach the southwestern
portion of Haiti within the next several hours. Hurricane
conditions are expected to reach eastern Cuba later today, the
southeastern Bahamas Tuesday evening, and the central Bahamas on
Wednesday. Tropical storm conditions are expected to continue
spreading across Haiti tonight, eastern Cuba later this morning, the
southeastern Bahamas later today, and the central Bahamas Tuesday
night, making outside preparations difficult or dangerous.
Preparations to protect life and property should be rushed to
Tropical storm conditions are expected in portions of Jamaica and
along the southern coast of the Dominican Republic within the
warning area today.
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.
