DISCUSSION AND OUTLOOK ---------------------- Data from Air Force Reserve and NOAA Hurricane Hunter aircraft indicate that Fiona's center has re-formed farther east. At 1100 AM AST (1500 UTC), the center of Tropical Storm Fiona was located near latitude 16.3 North, longitude 63.5 West. Fiona is moving toward the west near 8 mph (13 km/h). A west-northwestward motion at a similar forward speed is expected to begin later today, followed by a turn toward the northwest by Sunday evening. On the forecast track, the center of Fiona is expected to move near or south of the Virgin Islands this evening, approach Puerto Rico tonight, and move near or over Puerto Rico Sunday night. Fiona should then move near the Dominican Republic on Monday. Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Strengthening is forecast during the next few days, and Fiona is expected to become a hurricane by Sunday or Sunday night while moving near Puerto Rico. Tropical-storm-force winds extend outward up to 125 miles (205 km) from the center. Data from the reconnaissance aircraft indicate that the minimum central pressure is 1004 mb (29.65 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Tropical Storm 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 on Puerto Rico Sunday and Sunday night and are possible in the U.S. Virgin Islands tonight. Hurricane conditions are possible within the hurricane watch area in the Dominican Republic Sunday night and Monday. Tropical storm conditions will continue across portions of the Leeward Islands within the warning area through this afternoon. Tropical storm conditions will reach the U.S. and British Virgin Islands this afternoon, spread westward across Puerto Rico tonight, and reach portions of the Dominican Republic Sunday night. Tropical storm conditions are possible across the watch area in the Dominican Republic Sunday night. RAINFALL: Fiona is forecast to produce the following rainfall: Leeward Islands and Northern Windward Islands: Additional 2 to 4 inches. British and U.S. Virgin Islands: 4 to 6 inches with local maximum of 10 inches possible. Puerto Rico: 12 to 16 inches with local maximum of 20 inches possible, particularly across eastern and southern Puerto Rico. Dominican Republic: 4 to 8 inches with local maximum of 12 inches possible, particularly on the far eastern coast. Haiti: 1 to 3 inches with isolated maximum totals of 4 inches. Turks and Caicos: 4 to 6 inches. These rains are likely to produce flash and urban flooding, along with mudslides in areas of higher terrain, particularly southern and eastern Puerto Rico and the eastern 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. The water could reach the following heights above ground somewhere in the indicated areas in areas of onshore winds if the peak surge occurs at the time of high tide... Southern coast of Puerto Rico...1 to 3 ft Vieques and Culebra...1 to 3 ft U.S. Virgin Islands...1 to 2 ft Localized coastal flooding is also possible elsewhere in Puerto Rico. For information specific to your area, please see products issued by your local National Weather Service forecast office. 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. SURF: Swells generated by Fiona are affecting the Leeward Islands, the northern Windward Islands, the Virgin Islands, Puerto Rico, the northern coast of the Dominican Republic, the Turks and Caicos Islands, and the southeastern Bahamas. These conditions could cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
