  2. What in the world is a Tornado? • A tornado looks like a funnel shooting down from the sky • It is a violent whirling wind • Also referred to as a whirlwind, a twister, and a cyclone. • Can have winds up to 400+ mph. The tornado is rated by the damage it does. ( see Fujita scale) • Tornadoes spin counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

  3. How do Tornadoes form? • First you must have a low warm front • Next, a cold front should come under the warm front. • After that, another cold front should come up on top of the warm front keeping the warm air from rising. • The warm air should bust through the cold front on top and leaving a spiral of wind dragging underneath. This spiral of wind is a……… Tornado

  5. What is the difference between a tornado watch and a tornado warning? • Tornado watch—conditions are favorable for a tornado to occur • Tornado warning– a tornado has been sighted in the area

  6. Myth: Areas near rivers, lakes, and mountains are safe from tornadoes. Myth: Low pressure causes buildings to “explode” when a tornado passes. Fact: No areas are safe from tornadoes. Fact: Violent winds and debris cause most structural damage. Tornado Myths

  7. Fujita Scale • F0: Gale tornado • F1: Moderate tornado • F2: Significant tornado • F3: Severe tornado • F4: Devastating tornado • F5: Incredible tornado The Fajita scale measures the damage of the tornado and then rates it to the scale

  8. Water Spouts • Water spouts are tornadoes on WATER • They take in everything in their paths (boats, fish, water, ect.) • After all that, all the objects it sucked up comes raining down from the sky.

  9. Dust Devils • Dust Devils happen over dirt, sand, etc. • It has to be dry and windy. • A column of dust ( Dust Devil ) is not very dangerous. The only hazards are getting sand in your eyes. If the Dust Devil is powerful enough, it will pick up rocks and debris.

  11. Types of Tornadoes • Multiple-vortex • Water Spout • Land Spout • Gustnado • Dust Devil • Fire Whirl • Winter Waterspout

  12. Tornado Safety Environmental clues: Dark, often greenish sky Wall cloud Large hail Loud roar, almost like a freight train • In a home or building, move to a pre-designated shelter, such as a basement. • If an underground shelter is not available, move to an interior room or hallway on the lowest floor and get under a sturdy piece of furniture. • Stay away from windows. • Get out of automobiles. • Do not try to outrun a tornado in your car; instead, leave it immediately. • Mobile homes, even if tied down, offer little protection from tornadoes and should be abandoned. • Occasionally, tornadoes develop so rapidly that advance warning is not possible. Remain alert for signs of an approaching tornado. Flying debris from tornadoes causes most deaths and injuries. • DO NOT park under a bridge • If you are outside with no protection, go to a nearby ditch and lie down covering your head.
