DISCUSSION AND 48-HOUR OUTLOOK
At 1100 AM EDT (1500 UTC), the center of Hurricane Matthew was
located near latitude 14.0 North, longitude 74.6 West. Matthew is
drifting toward the west near 3 mph (6 km/h). A turn toward the
northwest is expected later today, followed by a turn toward
the north tonight. On the forecast track, the center of Matthew
will approach southwestern Haiti and Jamaica on Monday.
Maximum sustained winds are near 140 mph (220 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 Monday night.
Hurricane-force winds extend outward up to 35 miles (55 km) from the
center and tropical-storm-force winds extend outward up to 205 miles
The minimum central pressure reported by an Air Force Reserve
Hurricane Hunter aircraft is 947 mb (27.96 inches).
HAZARDS AFFECTING LAND
WIND: Hurricane conditions are expected to reach Jamaica and Haiti
on Monday, and eastern Cuba Monday night. Tropical storm conditions
are expected to first reach Jamaica and Haiti this evening, and
eastern Cuba early Monday, making outside preparations difficult or
dangerous. Preparations to protect life and property should be
rushed to completion. Tropical storm conditions are expected along
the southern coast of the Dominican Republic within the warning area
Hurricane conditions are possible in the hurricane watch areas by
late Tuesday with tropical storm conditions possible by early
Tuesday. Tropical storm conditions are also possible in the
tropical storm watch area in the Dominican Republic by late
RAINFALL: Matthew is expected to produce total rain accumulations of
15 to 25 inches over southern Haiti, with possible isolated maximum
amounts of 40 inches. Across western Haiti, expect total rain
accumulations of 8 to 12 inches with isolated maximum amounts of 16
inches, while northern sections of Haiti can expect lower amounts
in the 1 to 3 inch range with localized maxima near 5 inches.
Matthew is expected to produce total rain accumulations of 10 to 20
inches over eastern Jamaica, the Dominican Republic, and eastern
Cuba, with possible isolated maximum amounts of 25 inches. This
rainfall will likely produce life-threatening flash floods and mud
Matthew is expected to produce total rain accumulations of 8 to 10
inches over the southeastern Bahamas, with possible isolated maximum
amounts of 15 inches. Matthew is expected to produce total rain
accumulations of 2 to 4 inches, with possible isolated maximum
amounts of 6 inches over the Turks and Caicos Islands.
Matthew is expected to produce additional rain accumulations of 1 to
2 inches over Aruba, Curacao, and Bonaire through Sunday. Matthew
is expected to produce total rain accumulations of 2 to 4 inches
over northern Colombia, northwest Venezuela, and western Jamaica,
with possible isolated maximum amounts of 6 inches.
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...3 to 5 feet
Gulf of Gonave in Haiti...3 to 5 feet
Southern coast of the Dominican Republic...1 to 3 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 Puerto Rico, Hispaniola, Jamaica, Aruba, Bonaire,
Curacao, Venezuela, Colombia, eastern Cuba, and the Caribbean
coastline of Central America during the next few days. These swells
are likely to cause life-threatening surf and rip current
conditions. Please consult products from your local weather office.
