Tropical Storm Fiona is the first named storm in the Atlantic to make landfall since July 2.
The National Hurricane Center issued a hurricane warning for Puerto Rico on Saturday, as Tropical Storm Fiona is set to hit the island by Saturday night, becoming the first named Atlantic storm in months to make landfall in a historically quiet hurricane season.
Fiona is the sixth named storm this year, and only the third since Tropical Storm Colin, which formed off the coast of South Carolina in early July.
