A Storm Surge Warning means there is a danger of life-threatening inundation, from rising water moving inland from the coastline, during the next 36 hours in the indicated locations. For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. This is a life-threatening situation. Persons located within these areas should take all necessary actions to protect life and property from rising water and the potential for other dangerous conditions. Promptly follow evacuation and other instructions from local officials. A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. Preparations to protect life and property should be rushed to completion. A Tropical Storm Warning means that tropical storm conditions are expected within the warning area within 36 hours. A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, in this case within 36 hours. Interests elsewhere along the Mid-Atlantic and New England coasts of the United States should monitor the progress of Dorian. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND OUTLOOK ---------------------- At 200 AM EDT (0600 UTC), the eye of Hurricane Dorian was located near latitude 34.2 North, longitude 76.8 West. Dorian is moving toward the northeast near 15 mph (24 km/h), and this general motion is expected to continue with an increase in forward speed through Saturday. On the forecast track, the center of Dorian will move near or over the coast of North Carolina during the next several hours. The center should move to the southeast of extreme southeastern New England tonight and Saturday morning, and then across Nova Scotia late Saturday or Saturday night. Maximum sustained winds are near 90 mph (150 km/h) with higher gusts. Slow weakening is expected during the next few days. However, Dorian should remain a powerful hurricane as the center moves near or along the coast of North Carolina. Dorian is forecast to become a post-tropical cyclone with hurricane-force winds by Saturday night as it approaches Nova Scotia. Hurricane-force winds extend outward up to 60 miles (95 km) from the center and tropical-storm-force winds extend outward up to 220 miles (350 km). A Weatherflow station in Pamlico Sound, North Carolina, recently reported a sustained wind of 51 mph (82 km/h) and a wind gust to 70 mph (113 km/h). The Johnny Mercer Pier NOAA-NOS station located at Wrightsville Beach, North Carolina, recently measured a sustained wind of 42 mph (66 km/h) and a gust of 58 mph (93 km/h). The minimum central pressure based on data from the Air Force Hurricane Hunters and surface observations is 958 mb (28.29 inches). A report of 959.2 mb (28.32 inches) was recently measured at Wrightsville Beach Offshore buoy. HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are spreading along portions of the North Carolina coast. Tropical storm conditions are still affecting the northern portion of the South Carolina coast. Tropical storm conditions are expected in the Tropical Storm Warning area in the Mid-Atlantic states later today and over portions of extreme southeastern Massachusetts tonight or early Saturday. STORM SURGE: 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. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Surf City to Duck NC, including Pamlico and Albemarle Sounds and the Neuse and Pamlico Rivers...4 to 7 ft Duck NC to Poquoson VA, including Hampton Roads...2 to 4 ft Wrightsville Beach to Surf City NC...2 to 4 ft Water levels could begin to rise well in advance of the arrival of strong winds. The surge will be accompanied by large and destructive waves. Surge-related flooding depends on the how close the center of Dorian comes to the coast, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office. RAINFALL: Dorian is expected to produce the following rainfall totals through Friday Night: South Carolina...Additional amounts up to a half inch, isolated storm totals of 12 inches. Eastern North Carolina...Additional 3 to 8 inches, isolated storm totals of 15 inches. Far southeast Virginia...3 to 8 inches. Extreme Southeastern New England...2 to 4 inches. This rainfall may cause life-threatening flash floods. SURF: Large swells will affect much of the southeastern United States coast from northern Florida through North Carolina during the next couple of days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. TORNADOES: A few tornadoes are possible this morning across eastern North Carolina into southeastern Virginia.
