DISCUSSION AND 48-HOUR OUTLOOK
At 800 AM EDT (1200 UTC), the center of Hurricane Matthew was
located near latitude 21.5 North, longitude 74.9 West. Matthew is
moving toward the north-northwest near 10 mph (17 km/h). This
motion is expected to continue today, followed by a northwestward
turn tonight. On this track, Matthew will be moving across the
Bahamas through Thursday, and is expected to be very near the east
coast of Florida by Thursday evening.
Maximum sustained winds are near 115 mph (185 km/h) with higher
gusts. Matthew is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Some slight strengthening is forecast during
the next couple of days.
Hurricane-force winds extend outward up to 40 miles (65 km) from
the center, and tropical-storm-force winds extend outward up to 160
miles (260 km).
The minimum central pressure reported by NOAA and Air Force
Hurricane Hunter planes was 964 mb (28.47 inches).
HAZARDS AFFECTING LAND
WIND: Hurricane conditions are expected to continue affecting the
northwestern portion of Haiti this morning. Hurricane conditions
are likely occuring over eastern Cuba and portions of the
southeastern Bahamas. Hurricane conditions are expected to spread
over the central Bahamas later today and the northwestern Bahamas
Tropical storm conditions will continue over portions of Haiti and
eastern Cuba this morning. Tropical storm conditions are spreading
over the southeastern Bahamas and Turks and Caicos Islands, and
should reach the central and northwestern Bahamas later today,
making outside preparations difficult or dangerous. Tropical storm
conditions should diminish within the warning area in the Dominican
Republic this morning.
Hurricane and tropical storm conditions are possible in the
hurricane watch areas in Cuba this morning.
Hurricane conditions are expected within the hurricane warning area
in Florida by late Thursday, with tropical storm conditions expected
by early Thursday. Tropical storm conditions should reach the
tropical storm warning area in Florida 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...additional 1 to 2 inches, isolated storm totals
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
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 in southern
and northwestern Haiti, the southwestern Dominican Republic, and
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
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 Flagler/Volusia 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 a danger of
life-threatening inundation during the next 36 hours along the
Florida east coast from North Palm Beach to the Sebastian Inlet.
There is the possibility of life-threatening inundation during the
next 48 hours from Sebastian Inlet to the Flagler/Volusia 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, eastern Cuba, and the Bahamas 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.
