A decade ago, two powerful tornadoes went down in the history books, serving as a deadly reminder of how violent Tornado Alley can become and how quickly.
Next month will mark the 10-year anniversary of the pair of tornadoes that tore through Oklahoma. On May 20, 2013, a massive tornado rated at EF5 strength on the Enhanced Fujita Scale rocked Moore, Oklahoma, and surrounding cities, killing 24 and leaving hundreds injured. The destructive path of the twister, roughly 20 miles, caused around $2 billion in damage in 2013 USD, and the tornado remains the most recent EF5 to have touched down in the United States.
