Tornadoes are columns of air in very high rotation, which have high destructive power. The phenomenon happens in Brazil, but its occurrence is little recognized. In this work, we intend to characterize the multiple vortex tornado that occurred in Marechal Cândido Rondon and Quatro Pontes in 2015, to find out if there was the possibility of identifying the hook echo in the radar image. For that, the images made available by the Meteorology System of Paraná were compared with the course of the phenomenon. The analyzes performed allowed the glimpse of a hook in the area of occurrence, demonstrating that the event had a signature. However, the subscription took place very quickly, with only 7 minutes in advance.
