Before developing into Tropical Depression Nine, the precursor tropical wave dropped moderate to heavy rainfall across the Lesser Antilles.
The depression caused moderate rainfall in Puerto Rico, where two to three inches (50 to 75 mm) of precipitation were recorded.
The flooding from the rainfall entered ten houses and left some streets impassable.
A mudslide was reported in the eastern portion of the island.
A river in northeastern Puerto Rico surpassed its banks from flooding, though it returned to normal levels within hours.
Damage in Puerto Rico totaled $20,000 (2003 USD, $27.8 thousand 2020 USD).

The depression dropped over 1 inch (25 mm) of precipitation across much of the Dominican Republic; Santo Domingo reported a peak total of 3.9 in (98 mm).
The rainfall led to flooding, primarily east and west of the capital city, while five rivers overflowed their banks.
Several roads were inundated, obstructing traffic.
The flooding collapsed a sports center and a house, injuring two people inside.
Further inland, 160 people had to be evacuated when more than 100 houses were flooded.
Crop damage was also reported.
In Pedernales, gusty winds uprooted trees, several of which fell on power lines which caused power outages in the town.
The rainfall was welcomed in the country, as conditions were dry in the preceding months.
Light flooding also occurred in eastern Jamaica, though damage there, if any, is unknown.
