Storm surges

Storm surge can occur along all coastal areas of Canada. It can also occur in large lakes, such as the Great Lakes. A storm surge consists of very high waves and high water levels caused by wind and air pressure. It often results in coastal flooding. A storm surge can occur at any time of the year and can be particularly damaging in icy waters of winter.

Storm surges can happen quickly, without allowing much time for preparation. Residents, particularly those living in low-lying areas near the coastline, should prepare in advance.
