science does not yet completely understand how part of a thunderstorm’s energy sometimes gets focused into something as small as a tornado. Where And When Tornadoes Occur: North America. Whenever and wherever conditions are right, tornadoes are possible, but they are most common in the central plains of North America, east of the Rocky Mountains and west of the Appalachian Mountains. Other Areas Of The World. Tornadoes can also occur in many other areas of the world as well. They have been recorded in Australia, Europe, Africa, Asia, and South America as well as in North America. Spring And Summer. They occur mostly during the spring and summer, however, the tornado season comes early in the south and later in the north because spring comes later in the year as one moves

northward. They usually occur during the late afternoon and early evening. However, they have been know to occur in every state in the United States, on any day of the year, and at any hour. Damage: Wind. The damage from tornadoes comes from the strong winds they contain. It is generally believed that tornadic wind speeds can be as high as three hundred miles per hour in most violent tornadoes. Wind speeds that high can cause automobiles to become airborne, rip ordinary homes to shreds, and turn broken glass and other debris into lethal missiles. The biggest threat to living creatures, including humans, from tornadoes is from flying debris and from being tossed about in the wind. It used to be believed that the low pressure in a tornado contributed to the damage by making

buildings “explode” but this is no longer believed to be true. Detection Of Tornadoes: Doppler Radar. Today, the development of Doppler radar has made it possible, under certain circumstances, to detect a tornado’s winds with a radar. However, human beings remain an important part of the system to detect tornadoes because not all of them occur in situations where radar can “see” them. Ordinary citizen volunteers make up what is called SKYWARN (www.skywarn.org) network of storm spotters who work with their local communities to watch out for approaching tornadoes, so that those communities can take appropriate action in the event of a tornado. Spotter information is relayed to the National Weather Service, which operates the Doppler radars and which issues warnings,

usually relayed to the public by radio and televison, for communities ahead of the storms using all the information they can obtain from weather maps, modern weather radars, storm spotters, monitoring power line breaks, and so on. Prediction: Atmospheric Conditions. Tornadoes can be predicted, but only to a limited extent. Although the process by which tornadoes form is not completely understood, scientific research has revealed that tornadoes usually form under certain types of atmospheric conditions. Those conditions can be predicted, but not perfectly. When forecasters see those conditions, they can predict that tornadoes are likely to occur. However, it is not yet possible to predict in advance exactly when and where they will develop, how strong they will be, or precisely

what path they will follow. There are some “surprises” every year, when tornadoes form in situations that do not look like the right conditions in advance, but these are becoming less frequent. Once a tornado is formed and has been detected, warnings can be issued based on the path of the storm producing the tornado, but even these cannot be precise about who will or will not be struck. Environmental Clues. Some clues to look for in the environment that could give you an idea that a tornado is coming are that the sky gets dark and sometimes green, there are walls of clouds everywhere, even close to the ground, large hail comes down, and loud roars, like a freight train. These are all things that help us to determine if we may experience a tornado. Staying Safe: Safety Rules

To Follow. During a tornado, you should always take the proper safety rules so that you can stay safe with your family. The main rule to follow is be protected from flying and falling debris. If you hear a tornado warning, seek shelter immediately!! The storm is known to come at any given moment. Where To Go. During a tornado, you must seek shelter as soon as possible. A storm shelter is the best choice, if you have one. If you have a basement, go there and get under something sturdy to shelter you from falling debris. If you have no storm shelter or basement, go to an interior room without windows on the first floor of your home. Bathrooms are a good choice because the plumbing reinforces the walls. Closets are also a good choice because they normally have no windows. The idea
