DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 500 PM EDT (2100 UTC), the center of Hurricane Maria was located near latitude 31.7 North, longitude 73.1 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. A turn toward the north-northeast is expected on Wednesday. On the forecast track, the center of Maria will pass east of the coast of North Carolina during the next couple of days. Reports from a NOAA reconnaissance aircraft indicate that maximum sustained winds are near 80 mph (130 km/h) with higher gusts. Gradual weakening is forecast during the next couple of days, and Maria is forecast to become a tropical storm Tuesday night or Wednesday. Maria is a large hurricane. Hurricane-force winds extend outward up to 105 miles (165 km) from the center and tropical-storm-force winds extend outward up to 205 miles (335 km). NOAA buoy 41002, located about 100 miles west-northwest of Maria's center, recently reported sustained winds of 44 mph (70 km/h) and a gust to 56 mph (91 km/h). The minimum central pressure estimated from reconnaissance aircraft observations is 965 mb (28.50 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected within the warning 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: Large swells generated by Maria are affecting much of the east coast of the United States from Florida through southern New England. These swells are also affecting Bermuda, Puerto Rico, 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.
