The New ‘Tornado Alley’ [INFOGRAPHIC]
New Data released by the National Oceanic and Atmospheric Administration (NOAA) show that severe tornadoes extend far beyond the plains, from the Midwest, including South Dakota, to the Deep South.
The infographic, above, recognizes the tornado that ravished a large section of the Midwest as the deadliest tornado in United States history. Known as the “Tri-State Tornado”, the storm claimed 695 lives. It stayed on the ground for an unprecedented 219 miles, the longest ever recorded on the planet.
That tornado actually crossed the Mississippi River and carried sheets of iron from a Missouri steelworks and iron factory with it. It stayed on the ground for a record 3.5 hours and was reported to be 3 miles wide at times.
Heaven forbid we see another one with the intensity as the Tri-State tornado in our lifetime. The last F5 tornado in South Dakota occurred on May 8th, 1965 in Tripp County.
The Spencer, South Dakota tornado was the most destructive and second deadliest tornado in the history of the state. It packed winds of 220 mph and touched down Saturday, May 30, 1998.
However, as I write this and research the history of tornadoes in South Dakota, I realize it was 3 years ago today that the Dominator, a storm chasing vehicle, intercepts the EF4 that touched down on South Dakota farmland near the town of Bowdle.
