Ontario Tornado Update #1 - May 30
A number damaging wind events in Ontario required additional data collection and analysis. Those investigations have now been completed and the final tornado numbers for both Ontario and Canada can now be tallied for 2022.
Update #1 - May 30
A quasi-linear convective system in NW ON on this day resulted in a number of areas of damage. One tornado track (Boffin Lake) had been confirmed previously but is now updated based on additional data. Four new tornadoes (1 EF2, 3 EF1) have also been confirmed based on additional data collected and subsequent analysis. The details are provided in the summaries below.
