HURRICANE (Typhoon, Tropical Cyclones,Willy-Willies)
A hurricane is a tropical storm with wind speeds of 65 knots (120 km/h) to 240 knots (460 km/h) and can be thousands of square kilometers in size. These systems usually have a lifespan of several days.

In the North Atlantic, the hurricane season is from May to November, but the majority of storms occur in August, September and October. Although the east coast is the area of Canada most frequented by hurricanes, these storms still average less than one per year over the Atlantic provinces and coastal waters. There have been as many as five hurricanes in one year, however, several years can pass with no tropical storms.

A hurricane warning is issued in the Marine Forecast if winds are expected to exceed 64 knots (115 km/h).
