On the forecast track, the center of the storm is forecast to move through the Leeward Islands late Friday and Friday night, and be near the Virgin Islands and Puerto Rico this weekend. Satellite-derived wind data indicate that maximum sustained winds have increased to near 50 mph (85 km/h) with higher gusts. Some slow strengthening is possible during the next few days. Tropical-storm-force winds extend outward up to 140 miles (220 km) east of the center. The estimated minimum central pressure is 1002 mb (29.59 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are possible across portions of the northern Leeward Islands by Friday night, where a Tropical Storm Watch has been issued. RAINFALL: Fiona is expected to produce total rainfall accumulations of 3 to 5 inches with maximum totals of 8 inches across the northern Leeward Islands, the British and U.S. Virgin Islands, Puerto Rico and eastern Hispaniola. These rains may produce isolated flash and urban flooding, along with isolated mudslides in areas of higher terrain. SURF: Swells generated by Fiona are expected to begin affecting the northern Leeward Islands on Friday. These swells could cause life-threatening surf and rip current conditions.
