The tornado carved an extensive path of damage through the forest, snapping, uprooting and shearing the tops off of trees. A sauna was destroyed and its debris scattered, and a 60 metre-long dock was picked up from the water and deposited up a hill and in the forest, hundreds of metres from the shore. Boats were also tossed and destroyed. The tornado hit at 6:00 pm and had a path that was 1.6 kilometres long and 200 metres wide.
Figure 1 depicts the surface observations at 4:00 pm CDT, which shows a cold front west of Thunder Bay. This front became the focus for intense thunderstorms in the afternoon hours of June 26th, which ultimately led to this F1 tornado.
