Structured light has recently attracted the interest of scientific society while it is possible to control it in all its degrees of freedom and dimensions. I will present light spiraling like a tornado over its propagation. Such structured light can be generated by superimposing abruptly auto- focusing ring-Airy beams that carry orbital angular momentum of opposite handedness. This results to a complex wave with intense lobes that twist and shrink in an accelerating fashion along propagation.
