Wow, this past week was an interesting weak with weather.  It really hampered the practice rounds at the Master's Golf Tournament in Augusta.  It created some interesting situations here at the B & B also.  On Wednesday, Robin had to hunker down in one of the bathrooms as a tornado ripped through Edgefield, Johnston and Ward.  It was a very scary time but we are very thankful that we suffered no damage to the house itself.  We had a downed power and suffered damage to one of our trees that predated the Civil War.  The falling limbs caused damage to our wrought iron fence which is original to the house.  With a little cleanup our garden areas will be restored to their beauty.

The tornado was determined to be an F-2.  Prior to 1971, there was no way to measure and classify tornadoes.  Dr. Theodore Fujita developed a method for categorizing tornadoes.  The F-Scale or Fujita Scale looks at how much damage they cause and using this to estimate the wind speed.  It classifies tornadoes by their estimated wind speed, which is determined by looking at how strong the wind must have been to cause the resulting damage.
Tornados are classified into 5 catagories:

  • F-0 40-72 mph, Light damage, chimney damage, tree branches broken
  • F-1 73-112 mph, Moderate damage, mobile homes pushed off foundation or flipped over
  • F-2 113-157 mph, Considerable damage, mobile homes demolished, trees uprooted
  • F-3 158-205 mph, Severe damage, roofs and walls torn down, trains overturned, cars thrown around
  • F-4 207-260 mph, Devastating damage, well-constructed walls leveled
  • F-5 261-318 mph, Violent damage, homes lifted off foundation and carried considerable distances, autos thrown as far as 100 meters.
