Tornadoes form during severe thunderstorms when warm, moist air rises and meets cool, dry air. This creates strong updrafts and downdrafts that spin horizontally. If the wind changes direction and speed, it can make the spinning air tilt vertically, forming a tornado. Tornadoes are most common in Manitoba between May and September.
While tornadoes are often associated with certain regions, they can strike unexpectedly, making preparedness essential for everyone. While vulnerable areas such as homes with weak structures (mobile homes, areas with a lot of trees and debris) are at higher risk, tornadoes can strike anywhere.

While tornadoes are rare in Canada, they do occur. In 2023, there were 60 confirmed tornadoes across the country, with the majority occurring in the prairies. Manitoba stands out as one of the most tornado-prone provinces, with an average of 8 to 14 tornadoes per season.
When a tornado approaches, quick and informed action is essential. Whether at home, on a farm, or in larger structures, identifying the safest shelters and location-specific safety measures is critical.
