More new tornadoes from the 2023 satellite review
As was mentioned in a blog post late last year, after the end of the storm season NTP conducts a thorough hi-res satellite review of all forested regions to see if there are any areas of wind damage that we missed. That review turned up nine new tornadoes for 2023.
But 27 new tornadoes from before 2023 were also discovered in the process: 12 for 2022, 6 for 2021, 2 in 2020, 2 in 2019, 4 in 2018 and 1 in 2017.
Five of the new tornadoes are rated EF2 while the rest are rated EF1. Some of these occurred as part of past outbreaks, including 18 Jun 2017 (EF2 in QC), 21 Sep 2018 (EF1 in QC), 10 Jun 2020 (EF1 in QC), and 5 Jul 2021 (EF2 in QC).
Below is a map showing the locations of all of the new tornadoes, as well as an updated tornado count graph.
Following that are event summaries for each of the 27 new tornadoes, listed in chronological order.
Note that you can also plot and view the new tornadoes using the NTP Dashboard at https://uwo.ca/ntp/dashboard.
