A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area. For Bermuda, the tropical storm conditions are expected within the next 36 hours. 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. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 1100 PM EDT (0300 UTC), the center of Hurricane Joaquin was located near latitude 24.7 North, longitude 74.0 West. Joaquin is moving toward the northeast near 10 mph (17 km/h), and this general motion should continue with a gradual increase in forward speed during the next 48 hours. On the forecast track, the core of the strongest winds of Joaquin will continue to move away from the Bahamas. Data from an Air Force reconnaissance plane indicate that the maximum sustained winds remain near 125 mph (205 km/h) with higher gusts. Joaquin is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some weakening is forecast during the next 48 hours. Hurricane force winds extend outward up to 50 miles (85 km) from the center and tropical storm force winds extend outward up to 205 miles (335 km). The minimum central pressure reported by the Hurricane Hunter plane was 944 mb (27.88 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are expected to continue across portions of the central Bahamas for the next several hours. Tropical storm conditions will continue to affect portions of the southeastern Bahamas and the Turks and Caicos Islands during the next several hours. Tropical storm conditions are expected in Bermuda on Sunday. STORM SURGE: A very dangerous and life-threatening storm surge will raise water levels by as much as 6 to 12 feet above normal tide levels in the central Bahamas in areas of onshore flow. A storm surge of 2 to 4 feet above normal tide levels is expected in the remainder of the Bahamas within the hurricane warning area. Near the coast, the surge will be accompanied by large and dangerous waves. Water levels should begin to subside overnight and on Saturday as Joaquin moves away from the Bahamas. RAINFALL: Joaquin is expected to produce additional rain accumulations of 2 to 5 inches over the Bahamas, eastern Cuba, Haiti, the Dominican Republic, and the Turks and Caicos Islands through Saturday. Isolated maximum storm-total amounts of 25 inches are possible in the central Bahamas. Outer rain bands of Joaquin will begin to affect Bermuda by early Sunday, and Joaquin is expected to produce 3 to 5 inches of rainfall over Bermuda through Monday. This rainfall could result in life-threatening flash floods. SURF: Swells generated by Joaquin will affect portions of the Bahamas during the next few days. Swells have begun to affect portions of the southeastern coast of the United States and will spread northward along the east coast of the United States through the weekend. These swells are likely to cause life-threatening surf and rip current conditions. Even though Joaquin is expected to pass well east of the coast of the United States, a prolonged period of elevated water levels and large waves will affect the mid-Atlantic region, causing significant beach and dune erosion with moderate coastal flooding likely. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 200 AM EDT. Next complete advisory at 500 AM EDT. $$ Forecaster Avila |
