Random Weather Facts

Weather Terms
Enhanced Fujita Scale or EF-Scale - A scale of wind damage intensity in which wind speeds are inferred from analysis of wind damage. All tornadoes and most other windstorms are assigned a numerical rating from this scale according to the most intense damage caused by the storm. EF0 (weak) 65–85 mph, light damage EF1 (weak) 86–110 mph, moderate damage EF2 (strong) 111–135 mph, considerable damage EF3 (strong) 136–165 mph, severe damage EF4 (violent) 166–200 mph, devastating damage EF5 (violent) >200 mph, incredible damage

Weather History for March 15
 
1933   An F3 tornado passed directly across the city of Nashville, TN, causing nearly $1.5 million in damage.

1993   A blizzard known as "The Storm of the Century" affected the eastern United States. Record snowfalls paralyzed Georgia, Tennessee, and the Appalachians. Winds pushed snowdrifts 10 to 14 feet high in Tennessee and Pennsylvania. More than four and a half feet fell on Mount LeConte, Tennessee.
