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 1100 PM EDT (0300 UTC), the distinct eye of Hurricane Maria was located near latitude 27.0 North, longitude 72.5 West. Maria is moving toward the north near 9 mph (15 km/h), and this general motion is expected to continue through Monday. On the forecast track, the core of Maria will be moving well east of the United States southeast coast during the next 2 days. 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. Some fluctuations in intensity are likely during the next day or so. 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). NOAA buoy 41047 located north of Maria recently reported a sustained wind of 54 mph (86 km/h) with a gust of 75 mph (122 km/h). The minimum central pressure reported by an Air Force Hurricane Hunter plane was 942 mb (27.82 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 on 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.

Preparations to protect life and property should be rushed to completion. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. Interests elsewhere in Hispaniola and the Bahamas should monitor the progress of Maria. For storm information specific to your area in the United States, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. For storm information specific to your area outside the United States, please monitor products issued by your national meteorological service. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 500 PM AST (2100 UTC), the eye of Hurricane Maria was located near latitude 18.8 North, longitude 67.3 West. Maria is moving toward the northwest near 12 mph (19 km/h), and this general motion with a decrease in forward speed is expected through Thursday night. A turn toward the north-northwest is forecast on Friday. On the forecast track, the center of Maria will continue to move away from the northwestern coast of Puerto Rico this evening. The center will then pass offshore of the northeastern coast of the Dominican Republic tonight and Thursday and then move near the Turks and Caicos Islands and southeastern Bahamas Thursday night and Friday. Data from an Air Force Reserve Hurricane Hunter aircraft indicate that maximum sustained winds are near 110 mph (175 km/h) with higher gusts. Some strengthening is forecast during the next day or two, and Maria could regain major hurricane status by Thursday. Hurricane-force winds extend outward up to 60 miles (95 km) from the center, and tropical-storm-force winds extend outward up to 150 miles (240 km). The minimum central pressure based on data from the Air Force aircraft is 957 mb (28.26 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane and tropical storm conditions are still occurring over portions of Puerto Rico. Tropical storm conditions are spreading across the warning areas in the Dominican Republic, and hurricane conditions should start in the hurricane warning area tonight. Tropical storm conditions are expected to begin in the Turks and Caicos Islands and the southeastern Bahamas on Thursday, with hurricane conditions starting Thursday night. 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... Puerto Rico...3 to 5 ft The deepest water will occur along the immediate coast in areas of onshore wind over western portions of Puerto Rico, where the surge will be accompanied by large and destructive waves. 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. A dangerous storm surge accompanied by large and destructive waves will raise water levels by as much as 4 to 6 feet above normal tide levels in the hurricane warning area in the Dominican Republic, and 1 to 3 ft elsewhere along the northern coasts of the Dominican Republic and Haiti. A dangerous storm surge accompanied by large and destructive waves will raise water levels by as much as 9 to 12 feet above normal tide levels within the hurricane warning area of the southeastern Bahamas and the Turks and Caicos Islands. RAINFALL: Maria is expected to produce the following rainfall totals through Friday: Puerto Rico...20 to 25 inches, isolated 35 inches U.S. and British Virgin Islands...additional 3 to 5 inches Northern and eastern Dominican Republic, Turks and Caicos and southeast Bahamas...8 to 16 inches, isolated 20 inches Northern Haiti...2 to 4 inches Rainfall on these islands will cause life-threatening flash floods and mudslides SURF: Swells generated by Maria are affecting the Leeward Islands, Puerto Rico, and the Virgin Islands. These swells will begin affecting the northern coast of Hispaniola, the Turks and Caicos Islands, and the Southeastern Bahamas during the next day or two. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
