DISCUSSION AND 48-HOUR OUTLOOK
At 800 PM EDT (0000 UTC), the eye of Hurricane Matthew was located
over the western end of Grand Bahama Island near latitude 26.6
North, longitude 78.9 West. The hurricane is moving toward the
northwest near 13 mph (20 km/h), and this general motion is expected
to continue tonight with a turn toward the north-northwest early
Friday. On the forecast track, the eye of Matthew should move away
from Grand Bahama Island during the next few hours, and move close
to or over the east coast of the Florida peninsula through Friday
Reports from a NOAA Hurricane Hunter aircraft indicate that maximum
sustained winds are now near 130 mph (210 km/h) with higher gusts.
Matthew is a category 4 hurricane on the Saffir-Simpson Hurricane
Wind Scale. Some fluctuations in intensity are likely while the
hurricane moves toward the coast of Florida.
Hurricane-force winds extend outward up to 60 miles (95 km) from
the center and tropical-storm-force winds extend outward up to 185
miles (295 km). Settlement Point in the Bahamas recently reported
a sustained wind of 79 mph (128 km/h) with a gust of 105 mph (169
km/hr). The Lake Worth Pier near Palm Beach, Florida, recently
reported a sustained wind of 46 mph (74 km/h) and a wind gust of 60
mph (96 km/h).
The minimum central pressure estimated from NOAA Hurricane Hunter
data is 939 mb (27.73 inches).
HAZARDS AFFECTING LAND
WIND: Hurricane conditions will continue over portions of the
northwestern Bahamas this evening.
Hurricane conditions are expected to first reach the hurricane
warning area in Florida this evening and will spread northward
within the warning area through Friday. Tropical storm conditions
will continue to spread northward in the warning area along the
Florida east coast tonight and Friday.
Hurricane conditions are expected to spread northward in the warning
area in Georgia and South Carolina Friday night and Saturday with
tropical storm conditions expected on Friday.
Winds increase rapidly in elevation in a tropical cyclone.
Residents in high-rise buildings should be aware that the winds at
the top of a 30-story building will be, on average, about one
Saffir-Simpson category higher than the winds near the surface.
Tropical storm conditions are expected in the tropical storm warning
area in the Carolinas on Friday night and Saturday.
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…
Northwestern 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…
Sebastian Inlet, Florida, to Edisto Beach, South Carolina, including
portions of the St. Johns River…7 to 11 ft
Edisto Beach to South Santee River, South Carolina…4 to 6 ft
Boca Raton to Sebastian Inlet, Florida…4 to 6 ft
South Santee River, South Carolina, to Cape Fear, North Carolina…2
to 4 ft
Virginia Key to Boca Raton, Florida…1 to 3 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, the Georgia coast, and the South Carolina coast from
Boca Raton, Florida, to South Santee River, South Carolina.
There is the possibility of life-threatening inundation during the
next 48 hours from north of South Santee River, South Carolina, to
Cape Fear, North Carolina. 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.
RAINFALL: Matthew is expected to produce total rainfall amounts in
the following areas:
The central and northern Bahamas…8 to 12 inches, isolated 15
Coastal eastern Florida, Georgia, South Carolina, and southeast
North Carolina….5 to 10 inches, isolated 12 inches
Rainfall should diminish across central and eastern Cuba with
isolated additional amounts of 1 to 2 inches possible through this
TORNADOES: An isolated tornado or two is possible along the
east-central Florida coast tonight.
SURF: Swells generated by Matthew will continue to affect portions
of the north coast of Cuba and the Bahamas during the next few days,
and will spread northward along the east coast of Florida and the
southeast U.S. coast through the weekend. These swells will likely
cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.
