Tropical Storm Ana was the first named storm of the 2009 Atlantic hurricane season. Forming out of an area of low pressure associated with a tropical wave on August 11, Ana briefly attained tropical storm intensity on August 12 before weakening back to a depression. The following day, the system degenerated into a non-convective remnant low as it tracked westward. On August 14, the depression regenerated roughly 1,075 mi (1,730 km) east of the Leeward Islands. Early on August 15, the storm re-attained tropical storm status, at which time it was named Ana. After reaching a peak intensity with winds of 40 mph (64 km/h) and a barometric pressure of 1,003 mbar (1,003 hPa; 29.6 inHg), the storm began to weaken again due to increasing levels of wind shear and the unusually fast movement of Ana. In post-storm analysis, it was discovered that Ana had degenerated into a tropical wave once more on August 16, before reaching any landmasses.[1]
Numerous tropical storm watches were issued for the Lesser Antilles, Puerto Rico, Dominican Republic between August 15 and 17. Several islands took minor precautions for the storm, including St. Croix which evacuated 40 residents from flood-prone areas ahead of the storm. In the Dominican Republic, officials took preparations by setting up relief agencies and setting up shelters. Impact from Ana was minimal, mainly consisting of light to moderate rainfall. In Puerto Rico, up to 2.76 in (70 mm) of rain was reported, causing street flooding and forcing the evacuation of three schools.
