The episode as NWS BMX wrote it up.
During the last part of September, up to 4 inches of rainfall fell across the central portions of Central Alabama. This helped drought conditions in this area. Drought conditions ended for Talladega and Calhoun counties at the beginning of October, and up to 4 inches of rainfall that fell during the rest of the month, helped to keep those counties below the drought criteria.
