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 800 PM EDT (0000 UTC), the eye of Hurricane Maria was located near latitude 23.8 North, longitude 71.6 West. Maria is moving toward the north-northwest near 9 mph (15 km/h), and this general motion is expected to continue through Saturday. A turn toward the north is forecast by Saturday night. We are fortunate tonight to have an Air Force and a NOAA Hurricane Hunter aircraft sampling Maria. In fact, a Coyote unmanned aerial vehicle launched from the NOAA P3 aircraft successfully measured winds in the eyewall. Data from these platforms indicate that the 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. Gradual weakening is forecast during the next 48 hours. Hurricane-force winds extend outward up to 60 miles (95 km) from the center, and tropical-storm-force winds extend outward up to 160 miles (260 km). The minimum central pressure based on data from both reconnaissance planes is 953 mb (28.14 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions will continue over portions of the Turks and Caicos Islands and the southeastern Bahamas through tonight. Tropical storm conditions are expected to begin in portions of the central Bahamas tonight. STORM SURGE: Water levels in the southeastern Bahamas and the Turks and Caicos Islands will subside through tonight as Maria moves away from those islands. RAINFALL: Maria is expected to produce the following rainfall accumulations through Saturday: Turks and Caicos...8 to 16 inches, isolated 20 inches Puerto Rico...additional 1 to 3 inches, isolated maximum storm total amounts 40 inches Mayaguana, southeast Bahamas...4 to 8 inches Inagua Islands and Crooked Island, Bahamas...2 to 6 inches Rest of eastern Bahamas...1 to 3 inches Rainfall on these islands will continue to cause life-threatening flash floods and mudslides. SURF: Swells generated by Maria are still 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 tonight. 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 1100 PM EDT. $$ Forecaster Avila
