Tornado Alley
The term was first used in 1952 as the title of a research project to study severe weather in areas of Texas, Oklahoma, Kansas, South Dakota, Iowa, Missouri, Nebraska, Colorado, North Dakota, and Minnesota. It is largely a media-driven term although tornado climatologists distinguish peaks in activity in certain areas and storm chasers have long recognized the Great Plains tornado belt.
Moore, Oklahoma
The Oklahoma City metropolitan area (of which Moore is a part) is located in Tornado Alley and is subject to frequent and severe tornadoes and hailstorms, making it one of the most tornado-prone major metropolitan areas in the world.
