DISCUSSION AND OUTLOOK ---------------------- At 1100 PM EDT (0300 UTC), the center of Hurricane Fiona was located near latitude 20.6 North, longitude 70.3 West. Fiona is moving toward the north-northwest near 10 mph (17 km/h). This general motion is expected to continue through Tuesday, followed by a turn toward the north Tuesday night or Wednesday. On the forecast track, the center of Fiona will pass near easternmost Turks and Caicos late tonight or early Tuesday. Data from both NOAA and Air Force Reserve Hurricane Hunter aircraft indicate that the maximum sustained winds have increased to near 110 mph (175 km/h) with higher gusts. Additional strengthening is expected during the next couple of days, and Fiona is forecast to become a major hurricane later tonight or on Tuesday. Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 150 miles (240 km). The latest minimum central pressure estimated from reconnaissance aircraft data is 971 mb (28.68 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 expected in the Turks and Caicos beginning later tonight or early Tuesday. Tropical storm and hurricane conditions are possible within the hurricane watch area in the Dominican Republic tonight. Tropical storm conditions are expected in portions of the southeastern Bahamas by early Tuesday. RAINFALL: Fiona is forecast to produce the following rainfall: British and U.S. Virgin Islands: Additional 2 to 4 inches. Storm Total up to 10 inches on St. Croix. Southern Puerto Rico: Additional 3 to 6 inches with local maximum of 8 inches. Storm Total 12 to 20 inches with local maximum of over 30 inches. Northern Puerto Rico: Additional 1 to 3 inches with local maximum of 5 inches. Storm Total 4 to 12 inches with local maximum of 20 inches. Northern and Eastern Dominican Republic: Additional 4 to 8 inches with local maximum of 10 inches. Storm Total up to 20 inches in the eastern section. Rest of Dominican Republic and Eastern Haiti: 3 to 6 inches. Turks and Caicos: 4 to 8 inches. Southeast Bahamas: 1 to 3 inches. These rains will continue to produce life-threatening and catastrophic flooding along with mudslides and landslides across Puerto Rico. Life-threatening flash and urban flooding is likely for eastern portions of 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 5 to 8 feet above normal tide levels along the immediate coast in areas of onshore winds in the Turks and Caicos tonight into Tuesday. Storm surge will raise water levels by as much as 1 to 3 feet above normal tide levels along the immediate coast in areas of onshore winds in the Dominican Republic. Localized coastal flooding is possible for the Southeastern Bahamas in areas of onshore winds tonight into Tuesday. 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. The swells could cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 200 AM EDT.
