The 1974 Tornado Outbreak

The 1974 Tornado Outbreak, or the Super Tornado Outbreak, was a widespread outbreak of tornadoes in the United States and Canada. According to the National Oceanic and Atmospheric Administration, it was the worst outbreak of tornadoes in United States history. The damage, number of tornadoes and the length of all the tornadoes paths of destruction combined give it this distinction. Surprisingly, the 1925 Tri-State Tornado was more than twice as deadly, though nowhere near as widespread.

The forecast on April 2, 1974 called for severe thunderstorms - a problem, but not indicative of what was really to come. On April 3, the outbreak began. The worst of it took place between 2 and 10 pm, but the storms continued until April 4. One hundred forty-eight tornadoes occurred in 13 states and Canada.

South Carolina, North Carolina, Virginia, West Virginia, Tennessee, New York, Illinois, Ohio, Alabama, Georgia, Mississippi, Michigan and Kentucky were affected. Six of the tornadoes were a five on the Fujita scale. More than 20 were rated four and more than 30 were rated three. Ohio, Indiana, Kentucky and Alabama were hit with the F5s.

The 1974 Tornado Outbreak carved more than 2,500 miles of destruction. One hundred eighteen tornadoes had destruction paths that measured a mile or more. Three hundred thirty people died and more than 5,000 were injured. The April 2011 outbreak death toll and number injured is eerily similar to the 1974 outbreak as of April 28, 2011.

Nineteen seventy-three was also a very active year for tornadoes. There were roughly 1,100 in all. Nonetheless, no outbreak took place that year that could compare to the one that took place the following April. Judging by the April tornadoes of 2011, it is not out of the question, though. It is quite possible that a similar or worse outbreak will occur in the United States, which is the country most susceptible to tornado outbreaks on Earth.
