SUMMARY OF WATCHES AND WARNINGS IN EFFECT: There are no coastal watches or warnings in effect. Interests along the Carolina and Mid-Atlantic coasts should monitor the progress of Maria. Tropical storm or hurricane watches may be needed for a portion of the coast on Sunday. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 500 PM EDT (2100 UTC), the eye of Hurricane Maria was located near latitude 26.3 North, longitude 72.5 West. Maria is moving toward the north-northwest near 9 mph (15 km/h), but a turn toward the north is expected by tonight. A northward motion with a decrease in forward speed is forecast to then continue through Monday. On the forecast track, Maria will move away from the Bahamas and offshore of the southeastern coast of the United States. Maximum sustained winds are near 115 mph (185 km/h) with higher gusts. Maria is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. A gradual weakening trend is expected to begin late Sunday or Monday. Hurricane-force winds extend outward up to 60 miles (95 km) from the center, and tropical-storm-force winds extend outward up to 240 miles (390 km). The minimum central pressure from a NOAA Hurricane Hunter plane is 950 mb (28.06 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Maria are increasing along portions of the southeastern United States coast and Bermuda and will be increasing along the Mid-Atlantic coast tonight and Sunday. Swells also continue to affect Puerto Rico, 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.
