DISCUSSION AND 48-HOUR OUTLOOK
At 800 PM EDT (0000 UTC), the center of Hurricane Matthew was
located near latitude 33.8 North, longitude 77.3 West. Matthew is
moving toward the east-northeast near 13 mph (20 km/h), and this
motion is expected to continue tonight and early Sunday. On the
forecast track, the center of Matthew will be near the coast of
southern North Carolina by this evening.
Maximum sustained winds remain near 75 mph (120 km/h) with higher
gusts. While Matthew is expected to remain near hurricane strength
while the center is near the North Carolina coast, the system could
become a post-tropical cyclone later tonight or on Sunday.
Hurricane-force winds extend outward up to 25 miles (35 km) mainly
over water southwest of the center. Tropical-storm-force winds
extend outward up to 185 miles (295 km). During the past few hours,
Myrtle Beach has reported a wind gust of 74 mph (119 km/h) and
CORMP buoy 41024 has reported a wind gust of 67 mph (108 km/h).
The minimum central pressure estimated from Air Force aircraft data
is 981 mb (28.97 inches).
HAZARDS AFFECTING LAND
WIND: Hurricane and tropical storm conditions are expected to
continue over the warning area this evening, 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 tonight.
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...
Murrells Inlet, South Carolina, to Duck, North Carolina, including
portions of the Pamlico and Albemarle Sounds...3 to 5 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 Murrells Inlet, South Carolina to Salvo,
North Carolina including portions of the Pamlico Sound. There is
the possibility of life-threatening inundation during the next 48
hours 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 from northeast South Carolina into northeast North
Carolina and southeast Virginia, with possible isolated totals of 20
inches possible. This rainfall is leading to record-breaking
flooding over portions of eastern North Carolina, and it may result
in life-threatening flooding and flash flooding elsewhere across the
TORNADOES: A couple of tornadoes are possible this evening 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.
