Tornado Safety

Introduction

A tornado is defined as "a mobile, destructive vortex of violently rotating winds having the appearance of a funnel-shaped cloud and advancing beneath a large storm system." Tornadoes can vary from just 50 yards to 1 mile in width. Most tornadoes in the US are small and weak (EF-0 or EF-1), but rare EF-5 tornadoes pack winds in excess of 200 mph!

There have been 13 major tornadoes in the Nashville/Davidson County area since 1974 and 10 tornadoes since 1994, and that includes three tornadoes in 1998 that caused major damage in several parts of the city.  (Source: Metro Nashville Office of Emergency Management)

In addition to these storms, on February 5, 2008, a series of storms damaged property southwest of Nashville and then passed through Davidson County.  The storm did not generate any tornadoes in Davidson county, but a short time after passing through this county, the same storm did spawn tornadoes northeast of town.  One of these tornados was nearly 3/4 of a mile wide with a 12-mile track; it killed 14 people in Macon County.

In 2011, the National Weather Service confirmed 80 tornadoes in Tennessee.  

Since 1950 there have been more than 300 tornado deaths in Tennessee.
