WIND: Hurricane conditions are occurring over portions of the 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: Additional local 1 to 2 inches over the next 24 hours. Southern Puerto Rico: Additional local 1 to 4 inches over the next 24 hours. Storm Total 12 to 20 inches with local maximum of 35 inches.

Southeast Bahamas: 1 to 4 inches. Bermuda: 1 to 3 inches. Heavy rainfall and localized life-threatening flash flooding continues over portions of the Dominican Republic today. Heavy rains around the center of Fiona impacts the Turks and Caicos through this afternoon with continued life-threatening flooding. Localized additional flash and urban flooding is possible in Puerto Rico. 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 through today. Localized coastal flooding is possible for the Southeastern Bahamas in areas of onshore winds through today. 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 spread across Bermuda later this week. The swells could cause life-threatening surf and rip current conditions.
