What is that Wikipedia, you have a backstory on the city of Moore, Oklahoma?
The city of Moore has been damaged by significant tornadoes on October 4, 1998, May 3, 1999, May 8, 2003, May 10, 2010, and May 20, 2013. The May 3, 1999 tornado that hit Moore was rated an F5 on the Fujita scale, and was one of the strongest (Probably the strongest single tornado ever) and most destructive tornadoes in world history.
Huh. Makes you think there might be some scientific reason that a certain area is getting hit by tornadoes multiple times or something.
