You go on the computer to look for maps on where tornadoes are occurring currently. You also look for areas that they are most common. You find out that tornadoes have a possibility of hitting anywhere but are most common in North America, Europe, East Asia and Australia.

In the United States they are most common in the areas known as tornado alleys. A tornado alley is a large area of land that tornadoes are found the most. In the United States there are three tornado alleys. One is found in the states of Colorado, North Dakota, Minnesota and central Texas. Another alley is found in Texas and Georgia. And the last alley is found in Arkansas, Ohio, Indiana, Illinois, Minnesota and the Ohio River.

One of the web sites that you were looking at said that one of the most important things for you to have when a tornado hits is a safety kit.

Then you come across a site that talks about how a tornado forms.
