More Basic Information Tornadoes start inside storm clouds called cumulonimbus, which are made up of warm, moist air. If the updraft and the downdraft in the storm come together and begin to spin, a funnel shaped cloud forms inside the cumulonimbus thunderhead and sometimes tilts into a funnel that reaches down toward the ground. As the funnel cloud spins faster and faster, it sucks more and more warm air and becomes larger and louder and more powerful. If it touches the ground, a tornado is formed. Tornadoes involve lighting, thunder, rain, hail, and high winds. Tornadoes start inside storm clouds called cumulonimbus, which are made up of warm, moist air.

Safety If your home has a basement, go into it at once. If your house doesn’t have a basement go in to a bathroom or an interior closet far from the outside walls. Crouch down low, cover your head with your hands, and stay away from windows and outside walls. Stay alert for high winds. An National Weather Service warning indicates that a hazardous event is occurring or is coming in about 30 minutes to an hour. If your home has a basement, go into it at once.

Prediction Meteorologists sample a wide network of weather stations and use satellite pictures to map out the places of the large air masses circling the Earth. Since air masses interact in a mostly predictable way, meteorologists are able to predict weather patterns with some degree of accuracy.

The most dangerous tornado ever The crazy tornado of March 18, 1925 injured 2,027 people and killed 689 people. This tornado moved in a mostly straight line from Missouri to Indiana. It was a Tri-state tornado and went through Missouri, Illinois, and Indiana. Because it occurred a long time before the National Weather Service issued tornado warnings and watches, the tornado caught people by surprise, without time to find shelter. it’s area of destruction was 164 square miles and it cost $17,000,000. It’s path was 219 miles, it’s speed got as high as 73 miles, and it’s width was 1 mile.
