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 recede today. 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 office. 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 region. 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.
