DISCUSSION AND 48-HOUR OUTLOOK
At 500 PM EDT (2100 UTC), the eye of Hurricane Matthew was located
near latitude 19.8 North, longitude 74.3 West. Matthew is moving
toward the north near 9 mph (15 km/h). On this track the eye of
Matthew will move over the extreme portion of eastern Cuba in the
next few hours. A turn toward the north-northwest is expected by
Wednesday, followed by a northwest turn Wednesday night. Matthew is
expected to move near or over portions of the southeastern and
central Bahamas tonight and Wednesday, and approach the northwestern
Bahamas Wednesday night.
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 at least Thursday night.
Hurricane-force winds extend outward up to 45 miles (75 km) from the
center and tropical-storm-force winds extend outward up to 175 miles
The estimated minimum central pressure is 949 mb (28.03 inches).
HAZARDS AFFECTING LAND
WIND: Hurricane conditions are still affecting portions of Haiti.
Hurricane conditions are likely occuring over eastern Cuba, and will
begin in the southeastern Bahamas this evening, the central Bahamas
on Wednesday, and the northwestern Bahamas Wednesday night.
Tropical storm conditions are expected to continue spreading
across the remainder of Haiti, eastern Cuba and the southeastern
Bahamas tonight, and should reach the central and northwestern
Bahamas on Wednesday, making outside preparations difficult or
dangerous. Tropical storm conditions are still occurring in portions
the Dominican Republic within the warning area, and these conditions
will spread northward into the Turks and Caicos Islands tonight.
Hurricane conditions are possible in the hurricane watch areas in
Cuba tonight with tropical storm conditions possible later tonight.
Hurricane conditions are possible within the hurricane watch
area in Florida by late Thursday, with tropical storm conditions
possible by early Thursday. Tropical storm condition are also
possible in the Florida tropical storm watch area by early Thursday.
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...4 to 6 inches, isolated 12 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 2 inches, isolated 3 inches
Upper Florida Keys northward to coastal east-central Florida....4 to
7 inches, isolated 10 inches
Middle to Lower Florida Keys....1 to 3 inches, isolated 5 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
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
The water could reach the following heights above ground if the peak
surge occurs at the time of high tide...
North Palm Beach to the Volusia/Brevard county line...3 to 5 ft
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.
The combination of a dangerous storm surge and the tide will cause
normally dry areas near the coast to be flooded by rising waters
moving inland from the shoreline. There is the potential for
life-threatening inundation during the next 48 hours along
the Florida east coast from North Palm Beach to the Volusia/Brevard
county line. For a depiction of areas at risk, please see the
Prototype National Weather Service Storm Surge Watch/Warning
Graphic. For information specific to your area, please see products
issued by your local National Weather Service forecast office.
The Prototype Storm Surge Watch/Warning Graphic is a depiction of
areas that would qualify for inclusion under a storm surge watch or
warning currently under development by the National Weather Service
and planned for operational use in 2017. The Prototype Graphic is
available at hurricanes.gov.
SURF: Swells generated by Matthew will continue to affect portions
of the coasts of Hispaniola, Jamaica, 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.
