NOAA/National Hurricane Center

The tropical storm is expected to reach the Virgin Islands and Puerto Rico this weekend.

RAIN : Fiona is expected to produce total precipitation accumulations 3 to 6 inches with higher isolated amounts in the north Leeward Islands, British and US Virgin Islands, Puerto Rico and eastern Hispaniola. These rains can produce flash and urban rains flooding, as well as isolated landslides in areas of higher ground.

Wide viewing angle

Although a lot can change in 5 days, it should curve north of Hispaniola and then become more interesting for the Bahamas and the eastern United States.
