This probable tornado was confirmed by Environment Canada as an F0 tornado. Figure 1 depicts the surface observations at 1:00 pm CDT, which depicts a low pressure system in the extreme southeastern Manitoba corner. This low pressure brought southerly flow into northwestern Ontario.
While not substantial, vertical lift promoted pop-up thunderstorms throughout the afternoon. The setup and location of this tornado leads us to believe that this was likely a landspout tornado.
According to Environment and Climate Change Canada (2018), an F0 tornado touched down at 2:45 pm EDT near Devlin, ON. The track and width of the tornado was not documented by ECCC. The tornado caused no fatalities, injuries or property damage.
