Severe Rainstorms

Thunderstorm safety

Thunderstorms can bring lightning, heavy rain, hail, strong winds and tornadoes. Be aware of weather conditions and warnings. Seek shelter immediately if a warning has been issued.

When indoors

• Stay away from windows, skylights and glass doors – strong winds and large hailstones can shatter them.
• Avoid taking showers or baths.
• Remain indoors 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.

When outdoors

• If thunder is heard, that means lightning is close enough to be dangerous – take shelter in an enclosed building or metal-topped vehicle.
• If there’s no shelter, go to a low-lying area away from tall, isolated objects – crouch down, do not lie down.

Lightning safety

On average, Canada experiences more than two-million lightning strikes annually. If thunder is heard, there is a risk of being struck by lightning.

When indoors

• Avoid running water in the house – lightning can enter through pipes and plumbing.
• Remain indoors for 30 minutes after the last roar of thunder as lightning can happen at the end of a storm.
• Do not handle electrical equipment, telephones or plumbing as they can conduct a lightning bolt.

When outdoors

• Go to the nearest solid brick building – sheds, picnic shelters, tents and covered porches do not protect from lightning.
• If there is not a sturdy building nearby, get into a metal-roofed vehicle and close all the windows.
• Stay away from tall objects such as trees, poles, wires and fences.
• If out on the water, get to shore immediately.
• If there are no nearby shelters, go to a low-lying area.
• If a person has been struck by lightning, call 911 immediately – victims of lightning strikes do not carry an electrical charge.
