The most recent record with damage, injuries or deaths is the March 15, 2025 tornado (2 deaths and 2 injuries).

The tornado formed and intensified quickly about two miles south of Plantersville along County Road 63, uprooting swaths of trees right from the start. The tornado travelled northward into Plantersville and intensified to its maximum intensity of a 140 MPH EF3 tornado in the south end of town, where trees across the entire area were uprooted, snapped, and even debarked. Several homes and businesses were destroyed, which unfortunately resulted in two fatalities and two injuries. The tornado began a more northeasterly trajectory as it left Plantersville, but still remained strong as it crossed into Autauga County.
