The Hurricane Hazard

The Annual Atlantic Hurricane Season commences June 1 and ends on November 30. Tropical Storms and Hurricanes are caused by a combination of warm tropical oceans, light winds and moisture along with pre-existing weather disturbances.

Hurricanes bring heavy rain, strong winds and large waves which often damage many homes, cars, buildings and trees.

Hurricanes are grouped into 5 categories, which tell you how strong they are. The Saffir-Simpson Hurricane Scale is a 1-5 rating which is based on the present intensity of the hurricane. Wind speed is the determining factor in the scale. Category 5 hurricanes are the strongest. Hurricanes have wind speeds of 74 mph or more, and their winds spin in an anti-clockwise direction around the centre (“eye”) of the hurricane.

  • Advisory

    Issued at regular intervals when a tropical storm or hurricane is first detected in the area.

  • Watch
