Hurricanes
A hurricane is a tropical cyclone with winds exceeding 120 km/h, heavy rainfall, storm surge, and large waves. Hurricanes can vary in size from less than 100 km to over 1000 km across and can last from a few hours to a few weeks. Hurricane season usually lasts from June through November, when the waters of the Atlantic Ocean are warm enough to produce a tropical cyclone.
Hurricanes are measured using the Saffir-Simpson Wind Scale which classifies hurricanes in five categories (where 1 is the lowest and 5 is the highest).
Why prepare for a hurricane
Tropical cyclones have killed more than 600 people in Canada since 1900. Communities close to the Atlantic Ocean are most at risk for a hurricane. The remnants of a hurricane can affect Ontario and Quebec. On rare occasions, remnants of tropical cyclones in the Pacific can affect British Columbia. Hurricanes can have a significant cost impact to people in Canada.
