South Dakota Tornado Tracks: A Visual History

South Dakota has a history of tornadoes. The following images show the tracks of tornadoes in the state from 1950 to 2006. The images show the tornado tracks by Fujita scale (or F scale). For a detailed explanation of the scale, check out the Tornado Project.

 

F0

Definite concentrations in the Big Sioux, James and Vermillion watershed areas. Longer tracks are much more common in the wide open areas, but appear evenly distributed throughout the state compared with the shorter tracks.

F1

Still heavily concentrated in the east and southeast. Longer tracks are a greater percentage of the numbers overall.

F2

Longer tracks now at parity with shorter ones. Still concentrated in the southeast.

F3

Shorter tracks might haveĀ  slight advantage in numbers. That one in the northeast must have been remarkable, given the length and the strength of it.

F4

Six. For the first time, it is easy to count the number of tornadoes at a given level. Nothing at all in the western part of the state.

F5

South Dakota F5 Tornado Tracks 1950-2006

We’ve only had one F5 in the period from 1950 to 2006. It was in Gregory, South Dakota in 1965. Thankfully, no one was killed by this one, but the damage was remarkable to behold.

F6

No. We’ve not had any of those–nor has any state, to my knowledge. The destruction caused by this level of tornado would be mindblowingly awful.
