DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 1100 AM EDT (1500 UTC), the center of Hurricane Matthew was located near latitude 33.0 North, longitude 79.4 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 today, and be near the coast of southern North Carolina by tonight. Maximum sustained winds are 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). Sustained winds of 53 mph (85 km/h) with a gust to 69 mph (111 km/h) has been observed at a private weather station near Winyah Bay, South Carolina, within the past hour. A wind gust to 58 mph (93 km/h) was recently reported at Charleston, South Carolina. Strong wind gusts are also occurring well inland in North and South Carolina. Laurinberg, North Carolina, recently reported a wind gust of 55 mph (89 km/h). The minimum central pressure reported by an Air Force plane was 967 mb (28.56 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane and tropical storm conditions are expected to continue over the warning area in Georgia and 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 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 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 portions of the east coast of Florida during the next few days, and will spread northward along 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.
