In Québec, windstorms refer to winds that:

  • blow at 60 km/h or more for at least one hour
  • gust at 90 km/h or more

They may be associated with low-pressure systems or local meteorological events, and they can cause significant damage.

Tornadoes are rotating columns of high winds of up to 70 km/h. They can change paths abruptly, making them highly destructive.

Certain signs may indicate that a tornado is coming, including:

  • Extremely dark sky tinged with green or yellow
  • Frequent lightning and claps of thunder
  • Torrential rain
  • Hail
  • Rumbling or whistling sound
  • Funnel cloud at the base of a thunderstorm cloud

If you are outdoors:

  • Take cover in a secure building with a sturdy roof that can withstand the force of wind and the weight of snow.
  • If you are in an open area and no shelter is available, take cover in a ditch or a depression in the ground. Lay face down on the ground and protect your head with your hands.
  • Protect yourself from objects that could be projected by the wind.
  • Take special precautions if you live near the shore, as high winds can create large waves. Never go near the water to watch a storm.
  • Follow the evolution of the situation and respect the instructions given by official sources of information (for example, your municipality, the Gouvernement du Québec).

The following places do not provide adequate shelter:

  • Vehicles
  • Mobile homes
  • Buildings with a huge roof, like a gymnasium, church or barn, as the roof is likely to collapse

If you are in a vehicle or at one of these places, leave it immediately and find a safe shelter.

Never approach a tornado. Just the opposite, get away from it and protect yourself from it.

If you are outside and are not able to get away from the tornado or find shelter inside a safe building, position yourself a good distance from any trees, utility poles or power lines.

What to do after

You may return to your home when officials have given their permission and it is safe to do so. Return home during the day when it is easier to see problems and hazards.

Never approach a downed power line. Call 911 immediately. There is a high risk that the line is live and that the nearby ground is electrified.

When you arrive, take pictures or videos to document the damage to your home and notify your insurer.

If extensive work must be carried out before you can return to your home, increase the security to keep away looters and inquisitive individuals:
