Lightning / Thunderstorm

All thunderstorms can be dangerous as they all produce lightning. Lightning injures more than 150 people in Canada every year.

Thunderstorms can happen any time of year. They can bring high winds and heavy rain, which can lead to flash flooding and damage to property.

How Can I Prepare For A Thunderstorm?

What Should I Do During A Thunderstorm?

  • If you can see lightning or hear thunder, you are at risk of being hit by lightning. If you are outside and hear thunder or see lightning, immediately take shelter inside a building or a hard-topped vehicle. There is no safe place outside during a thunderstorm. If you’re on the water and see bad weather coming, head for shore immediately and take shelter.
  • Stay inside until 30 minutes after the last rumble of thunder.
  • Stay away from windows and doors.
  • Stay away from things that conduct electricity (e.g. corded telephones, appliances, sinks, bathtubs, radiators and metal pipes).
  • If you are in a car, park away from trees or power lines that might fall on you). Stay in the car until the storm passes.
