Thunderstorms

Lightning kills about nine Canadians each year and seriously injures more than 100 people. Be aware of weather conditions and seek shelter immediately if a warning has been issued.

How to prepare for Thunderstorms 

• Have a safe room in your home where everyone gathers during a storm that is away from windows, skylights and glass doors
• If there's a tornado, gather in a basement, storm cellar or interior room on the lowest floor
• Remove dead or rotting trees and branches that could fall and cause injury or damage
• Bring inside or tie-down garbage cans and lawn furniture
• Use surge protectors to protect your computer and other household items
• Receive instant weather alerts by downloading Environment Canada's WeatherCan mobile app
• Create a 72 hour emergency kit. Remember your pets
• Make a plan and practice it with your family

Thunderstorm Safety Tips

If you are indoors:

• Stay away from windows, skylights and glass doors. Strong winds and large hail can shatter windows.
• Avoid running water in your house. Lightning can enter through pipes and plumbing
• Don't take showers or baths during a thunderstorm
• Remain indoors during a thunderstorm and stay inside for at least 30 minutes after the last rumble of thunder
• Be prepared to seek shelter in a basement or interior room on the lowest level if conditions worsen

If you are outdoors:

• If you hear thunder, lightning is close enough to be dangerous. Take shelter in an enclosed building or metal-topped vehicle
• Avoid water, high ground, isolated trees, power lines and picnic shelters. Small, open structures don't protect you from lightning
• If there's no shelter, go to a low-lying area away from tall, isolated objects. Crouch down and put your feet together. Do not lie down
