On August 9, the National Hurricane Center (NHC) began monitoring a tropical wave associated with a small area of convective activity between the Cape Verde Islands and the western coast of Africa.

Preparations and impact

On the afternoon of August 15, the Government of the Netherland Antilles issued a tropical storm watch for St. Maarten, Saba and St. Eustatius. Later that day, the watch area was expanded to include the islands of Antigua, Barbuda, the British Virgin Islands, Montserrat, St. Kitts and Nevis, Anguilla and the United States Virgin Islands. Early on August 17, the watch was further extended to include Puerto Rico. Later that day, Dominica was also placed under the tropical storm watch. Shortly after, the islands of Guadeloupe, St. Martin and St. Barthelemy were placed under the watch. By the afternoon, areas in the eastern Dominican Republic between Cabo Engaño and Cabo Beata were placed under the watch. Shortly after Ana weakened to a depression, the tropical storm watch for Dominica was discontinued. Early on August 17, the watch was also discontinued for Antigua and Barbuda. By the late morning hours, only Puerto Rico, the Dominican Republic and the U.S. Virgin Islands remained under tropical storm watches as Ana entered the eastern Caribbean Sea.

In Puerto Rico, heavy rains from Ana triggered minor flooded but resulted in little or no damage. Rainfall was limited due to the unusually fast forward motion of the storm.
