On August 15, a tropical storm watch was given to the islands of St. Maarten, Saba, St. Eustatius, Antigua, Barbuda, the British Virgin Islands, Montserrat, St. Kitts and Nevis, Anguilla, and the United States Virgin Islands. Later on August 17, Puerto Rico, Dominica, Guadeloupe, St. Martin, and St. Barthelemy were also put on tropical storm watch. When Ana weakened into a remnant low later that day, all watches were stopped.
