Tropical Storm Fiona brought wind and rain to the Leeward Islands on Friday night. At 11:00 p.m. EDT on Friday the center of Tropical Storm Fiona was located at latitude 16.6°N and longitude 62.2°W which put it about 55 miles (90 km) west-northwest of Guadeloupe. Fiona was moving toward the west at 14 m.p.h. (22 km/h). The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h). The minimum surface pressure was 1002 mb.

Tropical Storm Warnings were in effect for Saba, St. Eustatius, St. Maarten, Antigua, Barbuda, St. Kitts, Nevis, Montserrat, Anguilla, Guadeloupe, St. Martin and St. Barthelemy, Puerto Rico, Culebra, Vieques, the U.S. Virgin Islands, the British Virgin Islands and the portion of the coast from Cabo Caucedo to Puerto Plata, Dominican Republic. Tropical Storm Watches were in effect for Dominica and for the portion of the coast from Cabo Caucedo to Barahona, Dominican Republic.

More thunderstorms developed near the center of Tropical Storm Fiona on Friday night which caused Fiona to strengthen. Although there were more thunderstorms near the center of circulation, most of the thunderstorms were still occurring in bands on the eastern side of Tropical Storm Fiona. Bands in the western half of the circulation consisted primarily of showers and lower clouds. The new thunderstorms near the center of Fiona generated upper level divergence that pumped mass away to the north and east of the tropical storm. Winds to tropical storm force extended out 140 miles (220 km) from the center of Tropical Storm Fiona.

Tropical Storm Fiona will move through an environment somewhat favorable for intensification during the next 24 hours. Fiona will move over water where the Sea Surface Temperatures are near 29˚C. An upper level ridge over the tropical Atlantic Ocean will produce southwesterly winds that will blow toward the top of Tropical Storm Fiona. Those winds will cause vertical wind shear. The wind shear will inhibit intensification. Tropical Storm Fiona could continue to strengthen gradually, but the wind shear will limit intensification during the next 24 hours.

Tropical Storm Fiona will move around the southern side of the subtropical high pressure system over the Atlantic Ocean. The high pressure system will steer Fiona toward the west-northwest during the next 36 hours. Tropical Storm Fiona will continue to cause gusty winds and locally heavy rain to the northern Leeward Islands during the next 12 hours. Heavy rain could cause flash floods in some locations. On its anticipated track Tropical Storm Fiona could be southeast of Puerto Rico by Saturday evening. Fiona could be near the eastern end of the Dominican Republic by Sunday evening. There is a chance that Fiona could be a hurricane by that time.
