Researchers with Western University's Northern Tornadoes Project confirmed a third tornado formed during severe thunderstorms in the London, Ontario area [1].
The updated finding increases the known scale of the weather system that impacted southwestern Ontario. Accurate tornado counts are critical for meteorological research and for improving future emergency response protocols in the region.
The storms occurred on May 19, 2024 [2]. These intense thunderstorms included a bow-echo storm, which created the atmospheric conditions necessary to spawn multiple tornadoes [3]. While some initial reports cited only two tornadoes in the area [4, 5], the Northern Tornadoes Project later confirmed three [1].
The weather system caused widespread disruption across the region. In addition to the tornadoes, the storms brought flooding and power outages to areas including Toronto and Mississauga [6]. One person died as a result of the severe storms that swept through Ontario [7].
The Northern Tornadoes Project specializes in the survey and analysis of tornado events across Canada. By analyzing ground-level damage and meteorological data, the team can identify tornadoes that may not have been witnessed by residents or captured on radar.
This third confirmation highlights the complexity of the May 19 event. The presence of a bow-echo storm often indicates a high-wind environment where small, fast-moving tornadoes can occur and dissipate quickly, making them difficult to detect without professional surveying.

The confirmation of an additional tornado underscores the volatility of bow-echo storm systems in southwestern Ontario. It demonstrates that the actual impact of severe weather events often exceeds initial reports, necessitating the specialized forensic work of the Northern Tornadoes Project to provide a complete record of regional climate risks.
