Tornadoes

Tornadoes are violent windstorms identified by their twisting funnel-shaped cloud. They are always produced by thunderstorms but not every thunderstorm produces a tornado. They travel between 20 and 90 km/hour, are erratic, and can change course suddenly. Do not chase tornadoes. Tornado Watch means the weather could develop a tornado. Tornado Warning means a tornado has been seen or it is very likely that one will develop shortly.

Warning Signs of Tornadoes

Severe thunderstorms with frequent thunder and lightning
An extremely dark sky sometimes highlighted by green or yellow clouds
A rumbling sound, such as a freight train or a whistling sound similar to a jet aircraft
A funnel cloud at the rear of a thunder cloud, often behind a curtain of heavy rain or hail

What To Do During a Tornado

If You Are Near A Building

Listen to your radio during severe thunderstorms.
If a Tornado Warning has been issued take cover immediately.
Go to the basement or take shelter in a small interior ground floor room, closet or hallway.
Protect yourself by sitting under a heavy table or desk.
Stay away from windows and outside walls and doors.
Do not use elevators.
Avoid large halls, churches, arenas, etc. – their roofs are more likely to collapse.
Stay close to the ground, protect your head and hide from flying debris.

If You Are Driving

If you are driving, try and get to a nearby shelter – drive away from the tornado at a right angle.
Do not get caught in a car or mobile home – take shelter elsewhere. If no shelter is available, lie face down in a ditch or culvert away from the vehicle or mobile home.
If a tornado seems to be standing still, it is either traveling away from you or heading right for you.
Stay close to the ground, protect your head and hide from flying debris.
