 On the afternoon of August 3, a Hurricane Hunters flight into the system confirmed the development of a well-defined center of circulation, slightly exposed from a disorganized area of thunderstorms.As a result, the system developed into Tropical Depression Five at 1200 UTC on August 3, while located about 85 miles (140 km) south of the mouth of the Mississippi River.Because the depression was initially located in an area of northerly wind shear and dry air, the National Hurricane Center forecast it to slowly intensify.
