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 Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. A Storm Surge Watch means there is a possibility of life- threatening inundation, from rising water moving inland from the coastline 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. 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 48-HOUR OUTLOOK ------------------------------ At 1100 AM EDT (1500 UTC), the center of Hurricane Maria was located near latitude 35.6 North, longitude 72.6 West. Maria is moving toward the north-northeast near 6 mph (9 km/h), and this motion is expected to continue today. Maria is forecast to accelerate east-northeastward on Thursday and Thursday night. On the forecast track, Maria will begin to move away from the coast of North Carolina later today and tonight. Reports from an Air Force Reserve reconnaissance aircraft indicate that the maximum sustained winds are near 75 mph (120 km/h) with higher gusts. Some weakening is forecast during the next 48 hours. Hurricane-force winds extend outward up to 105 miles (165 km) primary to the northeast of the center, and tropical-storm-force winds extend outward up to 230 miles (370 km). An observing site at Jennette's Pier in Nags Head, North Carolina, recently reported a sustained wind of 43 mph (69 km/h) and a gust of 51 mph (81 km/h). The estimated minimum central pressure based on reconnaissance aircraft data is 978 mb (28.88 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected within the warning area through today. 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 is expected to reach the following heights above ground if the peak surge occurs at the time of high tide... Ocracoke Inlet to Duck including the sound side of the Outer Banks...2 to 4 ft Surge-related flooding depends on the relative timing of the surge and the tidal cycle, 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. SURF: Large swells generated by Maria are affecting much of the east coast of the United States, Atlantic Canada, Bermuda, the Bahamas, and the Turks and Caicos Islands. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office for more information. NEXT ADVISORY ------------- Next intermediate advisory at 200 PM EDT. Next complete advisory at 500 PM EDT. $$ Forecaster Brown
