Tropical Storm Warning is in effect for Antigua, Barbuda, St. Kitts, Nevis, Montserrat, Anguilla, Saba, St. Eustatius, and St. Maarten. Tropical Storm Watch is in effect for Guadeloupe, St. Barthelemy, and St. Martin.

Tropical storm conditions are expected across portions of the northern Leeward Islands within the warning area beginning Friday evening.

Heavy rains from Fiona will reach the northern Leeward Islands Friday afternoon, spreading to the British and U.S. Virgin Islands and Puerto Rico Saturday into Sunday morning, and reaching eastern Hispaniola Sunday. This rainfall may produce flash and urban flooding, along with isolated mudslides in areas of higher terrain.
