DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 800 AM EDT (1200 UTC), the center of Hurricane Maria was located near latitude 30.8 North, longitude 73.0 West. Maria is moving toward the north near 7 mph (11 km/h), and this general motion with some decrease in forward speed is expected through Tuesday night. On the forecast track, the center of Maria will move well east of the southeast coast of the United States during the next day or so. Reports from reconnaissance aircraft indicate that maximum sustained winds have decreased to near 75 mph (120 km/h) with higher gusts. Additional weakening is forecast during the next 48 hours, and Maria is expected to weaken to a tropical storm by Tuesday night. Maria is a large hurricane. Hurricane-force winds extend outward up to 70 miles (110 km) mainly to the east of the center and tropical-storm-force winds extend outward up to 230 miles (370 km). The latest minimum central pressure reported by an Air Force Reserve Hurricane Hunter aircraft is 961 mb (28.38 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected within the warning area beginning Tuesday. Tropical storm conditions are possible within the watch area beginning Tuesday. 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... Cape Lookout 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. RAINFALL...Maria is expected to produce total rainfall accumulations of 1 to 2 inches over the Outer Banks of North Carolina through Wednesday. SURF: Swells generated by Maria are affecting portions of the coast of the southeastern United States and Bermuda and will be increasing along the coasts of the Mid-Atlantic and southern New England today. Swells also continue to affect Puerto Rico, portions of the Virgin Islands, the northern coast of Hispaniola, the Turks and Caicos Islands, and the Bahamas. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office for more information.
