Interests elsewhere in the Bahamas should monitor the progress of Maria. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 200 AM EDT (0600 UTC), the large eye of Hurricane Maria was located near latitude 24.4 North, longitude 71.9 West. Maria is moving toward the north-northwest near 8 mph (13 km/h), and a gradual turn to the north should begin later today. This motion will bring the core of Maria east of the Bahamas today, and then over the open waters of the western Atlantic. Maximum sustained winds remain near 125 mph (205 km/h) with higher gusts. Maria is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Little change in strength is expected through tonight, with a gradual weakening expected to begin on Sunday. Hurricane-force winds extend outward up to 60 miles (95 km) from the center and tropical-storm-force winds extend outward up to 185 miles (295 km). The minimum central pressure reported by an Air Force Reserve Hurricane Hunter aircraft was 952 mb (28.11 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are still likely over portions of the Turks and Caicos Islands and the southeastern Bahamas during the next several hours, but should subside later today. Tropical storm conditions are expected in portions of the central Bahamas today. STORM SURGE: Water levels in the southeastern Bahamas and the Turks and Caicos Islands will subside as Maria moves away from those islands. RAINFALL: Rains are expected to gradually diminish across portions of the Turks and Caicos as well as the eastern Bahamas as Maria continues to move north of those islands today. Additional rainfall amounts of an inch or less are expected over those areas today. SURF: Swells generated by Maria are affecting Puerto Rico, the Virgin Islands, the northern coast of Hispaniola, the Turks and Caicos Islands, and the Bahamas. These swells will begin to increase along portions of the southeastern United States coast and Bermuda today. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 500 AM EDT. $$ Forecaster Beven
