High Quality Content by WIKIPEDIA articles! Tropical Depression Nine was a weak tropical depression that developed and dissipated in the eastern Caribbean Sea in August 2003. It formed from a tropical wave on August 21 to the south of Puerto Rico, and was initially forecast to strengthen to tropical storm status, due to the favorable conditions for development in the area. However, wind shear developed over the system, and the depression degenerated to a tropical wave on August 22. The system produced moderate to heavy rainfall throughout its path. In Puerto Rico, the rains flooded ten houses, while in the Dominican Republic the precipitation led to overflown rivers and two injuries.
