Fortunately, most tornadoes are ranked as weak tornadoes. Nationally, about 68 percent of all tornadoes are classified as F0 or F1. Only about 1 in 100 tornadoes is classified as F4 or F5, however this 1 percent accounts for 26 percent of tornado deaths. Click here for a listing of F4 and F5 tornadoes from 1950 to November, 2006.

In the Paducah County Warning Area, which includes 58 counties in the Mid Mississippi and Lower Ohio Valleys, the period from 1990 to 2001 was relatively quiet. A very active period of tornadoes began in 2002. Fatal tornado outbreaks occurred in late April of 2002, early May of 2003, November of 2005, and again in early March of 2006.
A long-track F3 tornado killed over 20 people in the Evansville, IN area on November 6, 2005. Two more deadly tornadoes occurred later that month, each of which killed one person. They were in Marshall County (KY) on Nov. 15 and Ripley County (MO) on November 27. The most recent killer tornado in the Paducah County Warning Area was in Perry County, Missouri on March 11, 2006. Two persons were killed in this tornado. All the 2005-06 killer tornadoes were rated F2 or F3.
The strongest September tornadoes on record in the Paducah County Warning Area occurred on September 22, 2006. One F4 tornado struck Crosstown in Perry County, Missouri and continued through Jackson County, Illinois as an F2. In Massac County, Illinois, an F3 occurred on the same date.
On May 6, 2003, a tornado rated F4 intensity killed two persons in Pulaski and Massac Counties in Illinois.
Tornado fatalities in the Paducah County Warning Area occurred in late April of 2002, when 3 persons were killed in separate tornadoes. A tornado rated F4 intensity struck just northwest of Poplar Bluff, Missouri on April 24, 2002.
On January 3, 2000, F3 tornadoes struck Owensboro, Kentucky and Crittenden County, Kentucky. These tornadoes demonstrate just how vulnerable our region is during the winter. These two tornadoes caused about 70 million dollars in damage, along with a couple dozen injuries. January of 1999 was another active winter month, with tornadoes on the 21st and destructive severe thunderstorms on the 17th.
A major tornado outbreak on June 2, 1990 produced F4 tornadoes over southwest Indiana and the Wabash Valley of southeast Illinois. An F4 tornado that tracked through parts of Gibson and Pike Counties in Indiana killed 6 persons. Another F4 tornado with a much longer track began over Hamilton County, IL and ended over Lawrence County, IN, killing 1. The Wabash River Valley was not a part of the Paducah office's County Warning Area until the mid 1990's.
On May 29, 1982, ten lives were lost in an F4 tornado that tore through the Marion-Carbondale area of southern Illinois.
One of the most infamous tornadoes in U.S. history occurred in northern parts of the Paducah Warning Area. The Great Tri-state Tornado of March 18, 1925 was perhaps the deadliest and longest-lived in American history. This F5 tornado tracked an estimated 219 miles, killing 695 persons in its path. The tornado began near Ellington, Missouri and finally dissipated near Petersburg, Indiana. Jackson and Franklin Counties in southern Illinois suffered some of the most concentrated damage. Along a path from Gorham to West Frankfort, IL, 541 people were killed and 1423 seriously injured in just 40 minutes.
Despite the fact there was a continuous damage track, it is possible the Tri-state
Tornado could have been a series of tornadoes instead of one single tornado,
but we may never know for sure.
Tornadoes are classified according to the strength of their wind
speeds. Since tornadoes very seldom pass over wind equipment, their wind speeds
are estimated by examining damage patterns. The most commonly used scale of
tornado intensity was devised by Theodore Fujita. The following is the Fujita
scale of tornado intensity:
|Fujita rating||Wind speeds||Damage pattern|
|F0 (Gale tornado)||40 to 72 MPH||Light damage. Breaks branches off trees. Some damage to chimneys.|
|F1 (Moderate tornado)||73 to 112 MPH||Moderate damage. Peels surface off roofs. Attached garages may be destroyed. Mobile homes may be overturned.|
|F2 (Significant tornado)||113 to 157 MPH||Considerable damage. Roofs torn off frame houses. Mobile homes demolished.|
|F3 (Severe tornado)||158 to 206 MPH||Severe damage. Roofs and some walls torn off well-constructed houses. Heavy cars lifted off ground and thrown.|
|F4 (Devastating tornado)||207 to 260 MPH||Devastating damage. Well-constructed houses levelled. Structures with weak foundations blown off some distance.|
|F5 (Incredible tornado)||261-318 MPH||Incredible damage. Strong frame houses lifted off foundations and carried considerable distances to disintegrate. Trees debarked.|
|F6 (Inconceivable tornado)||319-379 MPH||These winds are very unlikely. Damage would be so complete as to be unrecognizable.|
