WIND: Tropical storm conditions are beginning across portions of the Leeward Islands within the warning area and will continue through Saturday.
Tropical storm conditions will spread westward to the U.S. and British Virgin Islands Saturday morning, and across
Puerto Rico Saturday afternoon and Saturday night. Tropical storm conditions are possible on Dominica this evening or tonight and cross 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.

Dominican Republic: 6 to 10 inches with maximum totals of 16 inches
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 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
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 and
northern Windward Islands, and are beginning to reach the Virgin
Islands and Puerto Rico. Swells will then reach 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.
