DISCUSSION AND 48-HOUR OUTLOOK At 500 PM EDT (2100 UTC), the center of Hurricane Joaquin was located near latitude 23.0 North, longitude 74.4 West. Joaquin is moving toward the southwest near 6 mph (9 km/h), and a westward or southwestward motion is expected through tonight. A turn toward the north is expected on Friday, and a faster motion toward the north is expected Friday night and Saturday. On the forecast track, the center of Joaquin will move near or over portions of the central Bahamas tonight and pass near or over portions of the northwestern Bahamas on Friday. Maximum sustained winds are near 130 mph (215 km/h) with higher gusts. Joaquin is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some additional strengthening is possible tonight and Friday, with some fluctuations in intensity possible Friday night and Saturday. Hurricane-force winds extend outward up to 45 miles (75 km) from the center and tropical-storm-force winds extend outward up to 175 miles (280 km). The estimated minimum central pressure is 936 mb (27.64 inches). HAZARDS AFFECTING LAND WIND: Hurricane conditions are expected to continue across portions of the central and southeastern Bahamas through Friday. Hurricane conditions are expected over portions of the northwestern Bahamas tonight and Friday. Tropical storm conditions will affect other portions of the southeastern Bahamas, and the Turks and Caicos Islands through tonight. STORM SURGE: A very dangerous and life-threatening storm surge will raise water levels by as much as 5 to 10 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. RAINFALL: Joaquin is expected to produce total rain accumulations of 10 to 15 inches over the central Bahamas with isolated maximum amounts of 20 inches. Rainfall amounts of 5 to 10 inches are expected over the southeastern Bahamas, with 2 to 4 inches over the northwestern Bahamas. This rainfall could result in life-threatening flash floods. Outer rain bands of Joaquin may affect portions of eastern Cuba, Haiti, and the Dominican Republic today and tonight. SURF: Swells generated by Joaquin will affect portions of the Bahamas during the next few days, and will begin to affect portions of the southeastern coast of the United States tonight and spread northward through the weekend. These swells are likely to cause life-threatening surf and rip current conditions. Regardless of Joaquin’s track, 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.
