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, the southeastern Bahamas, and the Turks and Caicos Islands should monitor the progress of Maria. Additional watches and warnings may be required today. 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 200 PM AST (1800 UTC), the eye of Hurricane Maria was located near latitude 16.6 North, longitude 63.6 West. Maria is moving toward the west-northwest near 10 mph (17 km/h), and this general motion is expected to continue through Wednesday night. On the forecast track, the eye of Maria will move over the northeastern Caribbean Sea today, and then pass near or over the Virgin Islands overnight and Puerto Rico on Wednesday. Maximum sustained winds are near 160 mph (260 km/h) with higher gusts. Maria is a potentially catastrophic category 5 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some fluctuations in intensity are likely during the next day or two, but Maria is forecast to remain an extremely dangerous category 4 or 5 hurricane until it moves near or over the Virgin Islands and Puerto Rico. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 140 miles (220 km). During the past few hours, the eye passed just north of NOAA buoy 42060, which reported 1-min average winds of 85 mph (137 km/h) and a wind gust of 94 mph (151 km/h). The estimated minimum central pressure is 927 mb (27.37 inches). NOAA buoy 42060 reported a minimum pressure of 955.7 mb (28.22 inches) as the eye passed. HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions will continue in portions of the hurricane warning area in the Leeward Islands this afternoon, and spread into the Virgin Islands and Puerto Rico tonight and Wednesday. Tropical storm conditions are occuring over the remainder of the Leeward Islands, and should spread into the Virgin Islands and Puerto Rico starting in the next several hours. Hurricane conditions are expected within the hurricane warning area in the Dominican Republic late Wednesday, with tropical storm conditions expected by early Wednesday. Tropical storm conditions are expected in the tropical storm warning areas in the Dominican Republic on Wednesday. Wind speeds atop and on the windward sides of hills and mountains and on high-rise buildings could be much stronger than the near- surface winds indicated in this advisory. STORM SURGE: A dangerous storm surge accompanied by large and destructive waves will raise water levels by as much as 7 to 11 feet above normal tide levels in the hurricane warning area near where the center of Maria moves across the Leeward Islands and the British Virgin Islands. 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 and the U.S. Virgin Islands...6 to 9 ft The deepest water will occur along the immediate coast near and to the north and east of the landfall location, 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. RAINFALL: Maria is expected to produce the following rain accumulations through Thursday: Central and southern Leeward Islands...10 to 15 inches, isolated 20 inches. U.S. and British Virgin Islands...10 to 15 inches, isolated 20 inches. Puerto Rico...12 to 18 inches, isolated 25 inches. Northern Leeward Islands from Barbuda to Anguilla...4 to 8 inches, isolated 10 inches. Windward Islands and Barbados...2 to 4 inches, isolated 6 inches. Eastern Dominican Republic...4 to 8 inches, isolated 12 inches. Rainfall on all of these islands will cause life-threatening flash floods and mudslides. SURF: Swells generated by Maria are affecting the Lesser Antilles. 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 PM AST. Hourly Tropical Cyclone Updates will commence at 300 PM AST as the eye is now well-defined in data from the San Juan Doppler radar. $$ Forecaster Beven
