  • A Tornado normally appears transparent until it picks up dust and mud from the ground, giving a dark colored appearance 
  • Most Tornadoes spin in a cyclonic direction while some rotate in the anticyclonic direction, depending on where the develop in comparison to the Earth’s hemispheres.

  • F1- 73-112mph: moderate damage, mobile homes pushed off foundation or flipped over 
  • F2- 113-157mph: considerable damage, mobile homes demolished, trees uprooted,  
  • F3- 158-205mph: severe damage, roofs and walls torn down, trains overturned, cars thrown around 
  • F4- 207-261 mph: devastating damage, well-constructed walls are leveled 
  • F5- 261-318 mph: violent damage, home damage, homes lifted of foundation and carried considerable distance, autos thrown as far as 100 meters
