Tornadoes are a dangerous force of nature that can wreak havoc in just a matter of minutes. They're a common weather threat in the United States and around the world.

They occur during the spring and summer in the central plains of the country, east of the Rocky Mountains, and west of the Appalachian mountains. They can also occur during any day of the year and at any hour.

Whenever there's a storm, look for tornado warning signs like a funnel-shaped cloud appearing in the sky. A tornado doesn't resemble the clouds you'd see on a normal day - it's usually larger and darker.

Another important tornado warning sign is debris falling from the sky. This is because tornadoes come with strong winds, which can pick up flying debris and deposit it miles away.

The sound of a tornado can be compared to the sounds of a train, a waterfall, or even the sound of a jet engine. It can also be compared to continuous rolling thunder or rumbling earthquakes.

Most people agree that the sound of a tornado is louder than other noises. That is because the air in a tornado's vortex is rotating rapidly. Think about how loud it is when you stick your head out of a car window during a thunderstorm.

If you hear the roaring of a tornado, you should go to an interior room in your home as soon as possible. This is because most tornadoes are powerful enough to destroy a house.
