The area receives an average annual rainfall of 55 inches, with the highest amounts occurring in the summer months. The basin is characterized by a flat topography and numerous waterways, including the Mississippi River and its tributaries.

Interesting climatic facts include the region's susceptibility to hurricanes and the increasing frequency of extreme weather events, such as heavy rainfall and droughts. Recent trends suggest an increase in precipitation and warming temperatures, which could lead to more frequent flooding and changes in the distribution of plant and animal species.
