No appreciable damage was caused by this tornado, but it was witnessed and photographed by diners at the Elmhirst Inn on Rice Lake. The tornado had the appearance of a classic tropical waterspout as it moved across the lake, then onto land as a slender elephant trunk tornado. It’s path was 2 kilometres long and 100 metres wide.
Figure 2 depicts the surface observations at 5:00 pm EDT, which shows a trough of low pressure moving across southern Ontario. This trough was the focus for thunderstorms and ultimately this F0 tornado.
