Tornadoes, also referred to as twisters are powerful column of high winds that are spun off from violent thunderstorms. These appear behind heavy rain and hail, moving at speeds up to 90 km/h.
Tornadoes can cause widespread devastation in a community within seconds;
Tornadoes can occur at any time giving you little to no advance warning. Most often they occur during moderate summer temperatures, accompanied by high relative humidity. Ontario averages approximately 12 tornadoes a year, usually between the months of May and September.
If you are outdoors or driving and spot a tornado seek shelter immediately, keeping in mind that tornadoes move very quickly and you should not attempt to out run them.
Environment Canada is responsible for warning and updating the public if weather conditions can produce tornadoes. When severe storm conditions exist keep up to date by listening to your local radio or television stations.
