Multiple-vortex tornado

The only times multiple vortices may be visible are when the tornado is first forming or when condensation and debris are balanced such that subvortices are apparent without being obscured.

Sub-vortices tend to form after vortex breakdown reaches the surface, resulting from the interaction of cyclonically incoming and rising air.

Although multi-vortex structures are common in tornadoes, they are not unique to them and can occur in other circulations, such as dust devils.

However, because of a lack of intense property damage, the tornado achieved a rating of EF3 on the Enhanced Fujita scale.

The infamous “Dead Man Walking” photo of it was at a juvenile stage of sub-vortices development.
