DISCUSSION AND 48-HOUR OUTLOOK
At 200 PM EDT (1800 UTC), the center of Hurricane Matthew was
located near latitude 33.7 North, longitude 79.0 West. Matthew is
moving toward the northeast near 12 mph (19 km/h), and this motion
is expected to continue today. On the forecast track, the center of
Matthew will continue to move near or over the coast of South
Carolina this afternoon, and be near the coast of southern North
Carolina by this evening.
Maximum sustained winds remain near 75 mph (120 km/h) with higher
gusts. Although weakening is forecast during the next 48 hours,
Matthew is expected to remain near hurricane strength while the
center is near the coasts of South Carolina and North Carolina.
Hurricane-force winds extend outward up to 25 miles (35 km) from
the center and tropical-storm-force winds extend outward up to 185
miles (295 km). A wind gust of 59 mph (94 km/h) was measured at a

HAZARDS AFFECTING LAND
WIND: Hurricane and tropical storm conditions are expected to
continue over the warning area in South Carolina this afternoon, and
spread northward elsewhere within the warning area through tonight.
Hurricane conditions are possible within the Hurricane Watch and
Tropical Storm Warning area in North Carolina by tonight or Sunday
morning, with tropical storm conditions expected later today.
STORM SURGE: The combination of a dangerous storm surge, the tide,
and large and destructive waves will cause normally dry areas near
the coast to be flooded by rising waters moving inland from the
shoreline. The water could reach the following heights above ground
if the peak surge occurs at the time of high tide...
Charleston, SC to Cape Fear, NC...5 to 7 ft
Cape Fear to Duck, NC, including portions of the Pamlico and
Albemarle Sounds...2 to 4 ft
Along the Georgia and South Carolina coasts southwest of Matthew's
center, inundation caused by Matthew's storm surge will slowly
The deepest water will occur along the immediate coast in areas of
onshore winds. 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. For information specific to your area, please see
products issued by your local National Weather Service forecast
There is a danger of life-threatening inundation during the next 36
hours along the coast from Altamaha Sound, Georgia, to Bogue Inlet,
North Carolina as well as from Cape Lookout to Salvo, North Carolina
including portions of the Pamlico Sound. There is the possibility
of life-threatening inundation during the next 48 hours from Bogue
Inlet to Cape Lookout, North Carolina and from Salvo to Duck, North
Carolina including portions of the Albemarle Sound. 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 rain accumulations of
8 to 12 inches near and east of Interstate 95 in South Carolina and
North Carolina, with possible isolated maximum amounts of 15 inches.
Matthew is expected to produce 2 to 6 inches of rain over central
South Carolina, western North Carolina, and southeastern Virginia.
In all of these areas rainfall may result in life-threatening
flooding and flash flooding.
TORNADOES: A couple of tornadoes are possible through early
tonight along the coast of North Carolina.
SURF: Swells generated by Matthew will continue to affect much of
the coast of the southeastern United States through early next week.
These swells will likely cause life-threatening surf and rip current
conditions. Please consult products from your local weather office.
