Catastrophic flooding occurred due to post-landfall rains from a storm. The storm, known as Edouard, had peaked at 60 mph. However, the slow bands of rain that followed were more destructive, pulling moisture from the Gulf and dumping heavy rainfall.

The rainfall totals were significant, with over 10 inches falling in some areas and up to 18-20 inches near Kountze. This excessive rainfall led to severe flooding.
