Severe Summer Storm
Severe rain and thunderstorms occur during summer months and may include lightning and hail. They may also develop into tornadoes if conditions are right.
Prepare for a severe summer storm
- Identify where you can take shelter during severe thunderstorms:
- Shelters should be easily accessible.
- Shelters should protect you from flooding as well as flying glass, debris and furniture.
- Prepare a survival kit.
- Talk to your family about what everyone should do if a severe thunderstorm occurs.
- Ensure valuables, important papers, and cherished items are not located in areas that may be flooded during a storm.
Stay safe during severe summer storm
If you are at home:
- Turn on your battery-powered radio and listen for updates. Usually Environment Canada will issue a severe thunderstorm warning which will be broadcasted on local radio and television stations. When a severe thunderstorm warning is issued, stay alert and listen for further weather updates in case the storm produces tornadoes.
- If time permits, secure anything that might be torn loose or blown away.
- Ensure your children, pets, and vehicles are inside.
- Close windows and shut outside doors. Stay away from windows as they could be broken by hail.
- If possible, unplug electrical appliances.
- Do not use the phone or other electrical equipment.
- Stay away from anything that may conduct an electrical charge like sinks, metal pipes, stoves, radiators, and fireplaces.
If you are at work or in a public building:
- Stay away from windows as they could be broken by hail.
- Avoid using the telephone or other items that may conduct an electrical charge.
If you are outside:
- Get off bicycles, motorcycles and tractors.
- If swimming or in a boat, get back to shore immediately.
- Stay away from telephone and power lines, fences, trees and hilltops.
- Seek shelter if possible. NEVER seek shelter under a tree.
- If you are caught in the open, crouch down with your feet close together and your head down (i.e., “leap-frog” position).
- Don't lie flat on the ground; by minimizing your contact with the ground, you reduce the risk of being electrocuted if a lightning bolt strikes the ground.
If you are driving:
- Stop the car and stay in it.
- Do not stop near trees or power lines that could fall.
- Do not stop in low-lying areas where flash floods could occur.
After a severe summer storm
- Wait at least 30 minutes before resuming any outdoor activities or using any electrical appliances.
- If you can, help anyone who is injured. If you are injured, seek medical help.
- Only use the telephone if you need immediate emergency assistance. Emergency crews may need all available lines.
- Listen to local radio and television stations for updates and instructions.
