• Canadian Hurricane Centre

Hurricanes are violent tropical storms. These extreme storms occasionally hit eastern Canada usually between June and November – September is the peak month. Vacationers heading to southern destinations should be aware that hurricanes directly affect the southeast United States and Caribbean during the same months.

Hurricane facts

• A hurricane is a tropical storm whose winds revolve around a center of low pressure.
• The centre is called the eye. In the eye of a hurricane there is a calm area of blue sky.
• Around the eye there are very strong winds – a minimum speed of 120 kilometres per hour – accompanied by torrential rains.
• Hurricanes cause more widespread damage than tornadoes because they are bigger – some as large as 1,000 kilometres across.
• The most destructive effect of a hurricane is the storm surge, often causing serious flooding.

During a hurricane

• Hurricanes can often be predicted one or two days in advance of their landfall.
• As a rule, hurricanes move slowly and batter communities for several hours.
• During hurricane season, pay attention to weather forecasts and warnings.
• If a hurricane warning has been issued, follow these guidelines for safety during the storm:
  
  • If you live on the coast or in a low-lying area near the coast, you should move inland and to higher ground. The high winds create huge waves at sea which, when they reach the shore, may become tidal waves or storm surges.
  • Make sure your emergency kit is close at hand, in a portable container such as a duffel bag or suitcase with wheels.
  • Do not go down to the water to watch the storm. Most people who are killed during hurricanes are caught in large waves, storm surges or flood waters.
  • If the eye of the hurricane passes over, there will be a lull in the wind lasting from two or three minutes to half an hour. Stay in a safe place. Make emergency repairs only and remember that once the eye has passed over, the winds will return from the opposite direction with possibly even greater force.
  • Listen for reports from authorities on your portable radio.
  • On a farm, it may be better to leave livestock unsheltered. During Hurricane Andrew, some horses left outside suffered less injury then those placed in shelters. This was because some shelters selected did not withstand the high winds. Horses were injured by collapsing structures and flying objects that may have been avoided on the outside.

Mobile homes

If you live in a mobile home:

• Position your mobile home near a natural windbreak such as a hill or clump of trees.
• Anchor the structure securely. Consult the manufacturer for information on secure tie-down systems.
• When a severe storm approaches, seek shelter in a more secure building.
• Staying in a mobile home during a hurricane can be more dangerous than going outside. When you go outside, lie down in a ditch or depression away from the mobile home and away from cars.
