A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. Interests elsewhere in the Dominican Republic and Haiti, as well as Cuba, the northwestern Bahamas, and Florida should monitor the progress of Irma. 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 Irma was located near latitude 18.5 North, longitude 64.7 West. Irma is moving toward the west-northwest near 16 mph (26 km/h), and this general motion is expected to continue for the next couple of days. On the forecast track, the extremely dangerous core of Irma will continue to move over portions of the Virgin Islands during the next couple of hours, pass near or just north of Puerto Rico this afternoon or tonight, pass near or just north of the coast of the Dominican Republic Thursday, and be near the Turks and Caicos and southeastern Bahamas late Thursday. Maximum sustained winds are near 185 mph (295 km/h) with higher gusts. Irma is a category 5 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some fluctuations in intensity are likely during the next day or two, but Irma is forecast to remain a powerful category 4 or 5 hurricane during the next couple of days. An unofficial observation on Buck Island in the U.S. Virgin Islands has recently reported sutained winds of 106 mph (171 km/h) with a gust to 131 mph (211 km/h). Hurricane-force winds extend outward up to 50 miles (85 km) from the center and tropical-storm-force winds extend outward up to 185 miles (295 km). The latest estimated minimum central pressure from reconnaissance datat is 920 mb (27.17 inches). HAZARDS AFFECTING LAND ---------------------- STORM SURGE: The combination of a life-threatening storm surge and large breaking waves will raise water levels ABOVE NORMAL TIDE LEVELS by the following amounts within the hurricane warning area near and to the north of the center of Irma. Near the coast, the surge will be accompanied by large and destructive waves. Northern Leeward Islands...7 to 11 ft Turks and Caicos Islands...15 to 20 ft Southeastern Bahamas...15 to 20 ft Northern coast of the Dominican Republic...3 to 5 ft Northern coast of Haiti and the Gulf of Gonave...1 to 3 ft The combination of a life-threatening 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... British and U.S. Virgin Islands except St. Croix...7 to 11 ft Northern coast of Puerto Rico...4 to 6 ft Southern coast of Puerto Rico and St. Croix...2 to 4 ft The deepest water will occur along the immediate coast in areas of onshore winds, 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. WIND: Hurricane conditions will continue today within the hurricane warning area in the Leeward Islands. Hurricane conditions are occurring over the British and U.S. Virgin Islands and will spread westward over portions of Puerto Rico later today. Hurricane conditions are expected to begin within the hurricane warning area in the Dominican Republic and and Haiti on Thursday, with tropical storm conditions beginning tonight. Hurricane conditions are expected in the warning area in the southeastern Bahamas and the Turks and Caicos Islands beginning Thursday night. Hurricane and tropical storm conditions are possible within the watch area in the central Bahamas and Cuba by Friday. RAINFALL: Irma is expected to produce the following rain accumulations through Saturday: Northern Leeward Islands...8 to 12 inches, isolated 20 inches Northeast Puerto Rico and the British and U.S. Virgin Islands...4 to 10 inches, isolated 15 inches Southwest Puerto Rico, the southern Leeward Islands, and Saint Croix...2 to 4 inches Southeast Bahamas and Turks and Caicos...8 to 12 inches, isolated 20 inches Northern Dominican Republic, northern Haiti, eastern and central Cuba...4 to 10 inches, isolated 15 inches Southwest Haiti...1 to 4 inches In all areas this rainfall may cause life-threatening flash floods and mudslides. SURF: Swells generated by Irma will affect the northern Leeward Islands, Puerto Rico, the Virgin Islands, the southeastern Bahamas, the Turks and Caicos Islands, the northern coast of the Dominican Republic, and portions of the southeast coast of the United States during the next several days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.

Hurricane Irma Forecast Discussion
000 WTNT41 KNHC 061448 TCDAT1 Hurricane Irma Discussion Number 30 NWS National Hurricane Center Miami FL AL112017 1100 AM AST Wed Sep 06 2017 The eye of Irma passed over Barbuda, St. Barthelemy, and St. Martin this morning, and will be moving over portions of the British and U.S. Virgin Islands shortly. A NOAA National Ocean Service observing site on Barbuda measured sustained winds of 103 kt with a gust to 135 kt earlier this morning before the anemometer failed. The station also reported a minimum pressure of 916.1 mb. A minimum pressure of 915.9 mb was reported on St. Barthelemy. An Air Force reconnaissance aircraft that performed a single pass through the eye this morning reported SFMR winds of 152 kt in the northwestern eyewall around 12Z. Assuming there are stronger winds in the northeastern eyewall, the initial intensity remains 160 kt for this advisory. Another Air Force aircraft is currently entering the storm. Irma is moving west-northwestward or 285/14 kt. A strong high pressure ridge extending from the central Atlantic westward is expected to keep Irma moving west-northwestward during the next 2 to 3 days. The track guidance is in good agreement during this period and the NHC track is along the southern edge of the guidance envelope in best agreement with the ECMWF and HFIP corrected consensus model. After that time, a shortwave trough moving southward over the east-central United States is expected to erode the western portion of the ridge. As a result, Irma is forecast to turn northwestward and northward, but there is still a fair amount of uncertainty regarding the exact timing and location of recurvature. The NHC forecast has been shifted eastward to be in better agreement with the latest model guidance, however it should be noted that there are numerous GEFS and ECMWF ensemble members that take Irma over and/or west of Florida. The updated NHC track is in best agreement with the latest ECMWF ensemble mean. Users are reminded that the average NHC track errors at days 4 and 5 are about 175 and 225 statue miles, respectively. Irma is forecast to remain within favorable atmospheric conditions and over warm waters during the next 3 to 4 days. Therefore, Irma is likely to remain a very powerful hurricane during this time, and the NHC intensity forecast is unchanged from the previous advisory through day 4. Since the 120-h forecast point is now offshore, the intensity forecast at that time has been adjusted accordingly. Now that Irma's eye is clearly visible in radar imagery from San Juan, Tropical Cyclone Updates with hourly position estimates will be issued starting at 1200 PM AST (1600 UTC). KEY MESSAGES: 1. Irma is a potentially catastrophic category 5 hurricane and will bring life-threatening wind, storm surge, and rainfall hazards to portions of the northern Leeward Islands, including the Virgin Islands and Puerto Rico today. 2. A hurricane warning is in effect for the northern coast of the Dominican Republic, the southeastern Bahamas, the Turks and Caicos, and portions of Haiti, with a hurricane watch in effect for the central Bahamas and much of Cuba. Irma is likely to bring dangerous wind, storm surge, and rainfall to some of these areas tonight through Friday. 3. Irma could directly affect the remainder of the Bahamas and Cuba as an extremely dangerous major hurricane later this week. Residents in these areas should monitor the progress of Irma and listen to advice given by officials. 4. Direct impacts from wind, storm surge, and rainfall are possible in the Florida Keys and portions of the Florida Peninsula beginning later this week and this weekend. However, given the forecast uncertainty at these time ranges, it is too soon to specify the location and magnitude of these impacts.
