Tornadoes

A tornado is a violently rotating column of extremely high winds that can last from a few minutes to several hours. Tornadoes can range from 10 m to over 1 km across and travel at an average speed of 15-30 km/h. This means tornadoes can quickly approach and pass over your location. The strongest tornadoes are associated with severe thunderstorms, often accompany heavy rain or hail, and generally occur between May and August. Tornadoes are likely to occur between 4:00 p.m. and 8:00 p.m.

Why prepare for a tornado

According to the Northern Tornadoes Project, Canada has the second highest number of tornadoes in the world after the United States, with an average of 97 tornadoes per year. Tornadoes can destroy buildings and throw large objects across wide areas. Extensive damage is more likely in densely populated southern parts of Canada. In 1912, Canada's deadliest tornado on record occurred in Regina, Saskatchewan, where 28 people were killed.
