DISCUSSION AND OUTLOOK ---------------------- At 200 AM AST (0600 UTC), the center of Tropical Storm Fiona was located near latitude 16.3 North, longitude 62.8 West. Fiona is moving toward the west near 14 mph (22 km/h). A westward to west-northwestward motion with a decrease in forward speed is expected through Sunday night. A turn toward the northwest is forecast on Monday. On the forecast track, the center of Fiona is expected to move near or just south of the Virgin Islands and Puerto Rico today into Sunday, and approach the southern or eastern coast of the Dominican Republic Sunday afternoon. Fiona is forecast to move across the Dominican Republic Sunday night and Monday. Maximum sustained winds are near 60 mph (95 km/h) with higher gusts. Gradual strengthening is forecast, and Fiona could be near hurricane strength when it reaches the Dominican Republic on Sunday. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center. A wind gust of 45 mph (72 km/h) was recently reported at Princess Juliana International Airport on Sint Maarten. Data from an Air Force Reserve Hurricane Hunter aircraft indicate that the minimum central pressure is 1000 mb (29.53 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: Tropical storm conditions will continue across portions of the Leeward Islands within the warning area through early this afternoon. Tropical storm conditions will reach the U.S. and British Virgin Islands this morning, spread westward across Puerto Rico this afternoon and tonight, and reach portions of the Dominican Republic early Sunday. Tropical storm conditions are possible on Dominica early this morning and across the watch area in the Dominican Republic beginning Sunday afternoon. RAINFALL: Fiona is forecast to produce the following rainfall totals: Leeward Islands and Northern Windward Islands: 3 to 6 inches. British and U.S. Virgin Islands: 4 to 6 inches. Puerto Rico: 4 to 8 inches with maximum totals of 12 inches, particularly across eastern and southern Puerto Rico. Dominican Republic: 6 to 10 inches with maximum totals of 16 inches possible. Haiti: 1 to 3 inches with isolated maximum totals of 5 inches. Turks and Caicos: 4 to 8 inches. These rains may produce flash and urban flooding, along with mudslides in areas of higher terrain, particularly in 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 2 ft Localized coastal flooding is also possible elsewhere in Puerto Rico and the U.S. Virgin Islands. 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 and Puerto Rico. Swells will spread westward to the northern coast of Hispaniola, the Turks and Caicos Islands, and the southeastern Bahamas over the weekend. These conditions could cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
