What is a tornado?

A tornado is a rotating column of air extending from a thunderstorm. Most violent tornadoes are capable of tremendous destruction with wind speeds of 250 mph. Damage paths can be in excess of one mile wide and 50 miles long.

Did you know?

From late February through March, the Bossier area has the highest probability for tornadoes in the nation!

Tornado Myths

Myth: Areas near rivers, lakes, an mountains are safe from tornadoes.
Fact: No place is safe from tornadoes. In the late 1980’s, a tornado swept through Yellowstone National Park leaving a path of destruction up an down a 10,000 ft. mountain.

Myth: As the tornado passes overhead the low pressure causes buildings to “explode”.
Fact: Most structural damage is caused by violent winds and debris slamming into buildings.

Myth: Windows should be opened before a tornado approaches to equalize pressure and minimize damage.
Fact: Opening windows allow damaging winds to enter the structure. Leave the windows alone; instead, immediately go to a safe place.

  • 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. If caught outside or in a vehicle, lie flat in a nearby ditch or depression.
  • Mobile homes, even if tied down, offer little protection from tornadoes and should be abandoned.
