Passage: A well-organized disturbance moved off the African coast on September 6 and rapidly developed into Tropical Depression Eleven. The NHC began issuing advisories on September 8 while it was 350 mi (560 km) northeast of Cape Verde. An after-the-fact review of satellite and ship reports indicated that the depression reached tropical storm-strength on September 7. However, because of its extreme eastern track, the storm's observational track did not include this information.For three days a large trough of low pressure northwest of the system steered it north-northwest towards cooler waters. Moderate to heavy rain was reported along the west coast of Africa, but no damage was reported. The system eventually weakened and merged with the low pressure trough. This unnamed storm was later added to the list of tropical storms in the annual summary for the Atlantic hurricane season.

Question: How much damage was reported along the west coast of Africa during the moderate to heavy rain?
no damage
