DISCUSSION AND OUTLOOK ---------------------- At 500 PM EDT (2100 UTC), the center of Hurricane Fiona was located near latitude 22.6 North, longitude 71.8 West. Fiona is moving toward the north-northwest near 8 mph (13 km/h). This general motion is expected to continue into tonight, followed by a turn toward the north on Wednesday. A turn toward the north-northeast with an increase in forward speed is expected on Thursday. On the forecast track, the center of Fiona will gradually move away from the Turks and Caicos tonight and Wednesday, and approach Bermuda late on Thursday. Maximum sustained winds are near 115 mph (185 km/h) with higher gusts. Fiona is a category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale. Strengthening is forecast during the next couple of days. Hurricane-force winds extend outward up to 35 miles (55 km) from the center and tropical-storm-force winds extend outward up to 150 miles (240 km). The estimated minimum central pressure is 957 mb (28.26 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Hurricane Fiona can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT2 and WMO header WTNT42 KNHC and on the web at hurricanes.gov/text/MIATCDAT2.shtml. WIND: Hurricane conditions are occurring over portions of Turks and Caicos and these conditions should continue for the next few hours. Tropical storm conditions are expected over portions of the southeastern Bahamas for the next several hours. RAINFALL: Fiona is forecast to produce the following rainfall: British and U.S. Virgin Islands: Up to an additional local 1 to 2 inches. Puerto Rico: Up to an additional local 1 to 2 inches. Storm Total 12 to 20 inches with local maximum of 35 inches. Dominican Republic: Up to an additional local 1 to 2 inches. Storm Total up to 20 inches in the eastern section. Turks and Caicos: Additional 2 to 4 inches with storm totals of 5 to 10 inches. Southeast Bahamas: 1 to 4 inches. Bermuda: 1 to 3 inches. Heavy rains around the center of Fiona will impact the Turks and Caicos through this evening with continued life-threatening flooding. Localized additional flash and urban flooding is possible in Puerto Rico and the Dominican Republic. STORM SURGE: The combination of storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. Storm surge could raise water levels by as much as 2 to 4 feet above normal tide levels along the immediate coast in areas of onshore winds in the Turks and Caicos through this evening. Localized coastal flooding is possible for the Southeastern Bahamas in areas of onshore winds through this evening. SURF: Swells generated by Fiona are affecting the Virgin Islands, Puerto Rico, the northern coast of Hispaniola, the Turks and Caicos Islands, and the southeastern Bahamas. These swells will continue to spread westward across the southwestern Atlantic toward the central and northwestern Bahamas and the east coast of the United States through midweek. Swells from Fiona are expected to reach Bermuda later this week. The swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
