The Northern Tornado Project (NTP) team investigated storm damage that occurred on the evening of September 3, 2020 at both Port Colborne and Washago. The preliminary results of their investigation is that there was a high end EF0 tornado in Port Colborne and a EF1 tornado in Washago. There have been five tornadoes that have been recenlty confirmed.

This brings the total number to 32 and we could potentially see more tornadoes in Ontario this year. NTP has only recently started investigating and confirming tornadoes in Ontario (see here for more information about the project, which was founded in 2017). NTP confirmed 23 tornadoes in 2018 and 13 tornadoes in 2019 in Ontario. Compare these numbers with the Ontario government’s average of 12. The average is expected to increase as tornado detection improves and we get a more complete picture of how often tornadoes occur.

This article focuses on the two tornadoes that occured on September 3. For information about the other recently confirmed tornadoes please see:

August 27, 2020 - EF1 at Mount Carmel and EF1 at Union

August 28, 2020 - EF0 at Point Clark

Port Colborne’s EF0 tornado (late evening) had a maximum wind speed 125 km/h, a path length of 1.1 km, and a maximum width of only 50 m. The tornado produced damage to some trees and houses.

We sincerely hope everyone stayed safe in the path of these tornadoes and thank you so much to all of those who sent in reports! Your reports are critical in confirming tornadoes and continuing our goal to raise awareness about them and severe weather. Thank you!
