Founded in 2017 at Western University with support from ImpactWX.com, NTP aims to detect and document all tornadoes in Canada and uncover Canada’s true tornado climatology. Now part of the Canadian Severe Storms Lab! See uwo.ca/ntp & cssl.ca.https://bsky.app/profile/westernuntp.bsky.socialhttps://bsky.app/profile/westernuntp.bsky.social/post/3mlp6w3pf5s2hIt took a little longer than usual to solve this case, but the NTP has confirmed an EF0 downburst and an EF0 tornado from the storm that affected the Lucan, ON area on May 9. The first Canadian tornado and downburst of the 2026 season.
