Tornado Stats

Most of the world's tornadoes happen in the United States. These tornadoes are around Tornado Alley. There are about 750 tornadoes each year in the U.S. An average of about 100 people are killed each year by tornadoes.

The fewest tornadoes cause the most damage. Violent tornadoes are very rare but they are the most destructive. Scientists now can make better forecasts because they have better equipment. This way they can warn people about tornadoes so not as many will die. They can't stop tornadoes, so the tornadoes will still cause a lot of damage.

The charts to the left show how fewest tornadoes can cause the most destruction. Click on the picture for a better explanation.

Tornado Forecasts

Tornadoes are hard to forecast. They don't last very long so there's not much time to figure out what's happening. Also, scientists don't really know how they form. They know what the weather's like when...more

Tornadoes are very dangerous. This is why it's important to know when they are going to form. Forecastors at the National Weather Service are always looking for storms that could pop up. Nobody knows exactly...more

Tornadoes

Tornadoes form from severe thunderstorms. They are very destructive because they have a high energy density. They also don't last very long. This makes it hard to learn about them. Since scientists don't...more
