On May 31, 2013, a significant meteorological event took place near El Reno, Oklahoma, where a record-breaking tornado developed during a severe weather outbreak across the central United States. This tornado was remarkable not only for its size, measuring a remarkable 2.6 miles in width, but it also appeared without much warning, leading to extensive destruction. As it touched down, it moved at high speeds, with winds reaching up to 295 miles per hour, classifying it as an EF5 tornado, the most severe classification in the Enhanced Fujita scale.

The tornado claimed the lives of eight people, including three storm chasers: Timothy Samaras, his son Paul Samaras, and Carl Young. This tragic aspect highlighted the risks associated with storm chasing, as weather enthusiasts often pursue these phenomena for research and adventure. The event resulted in over 150 injuries and widespread damage, including the obliteration of numerous structures and homes in its path. In total, the devastation caused made it one of the most severe tornado incidents in recent history.

Meteorologists from around the world took note of this tornado, using advanced radar technology that provided real-time data about the storm's development. The unprecedented scale and violence of the tornado prompted discussions on tornado preparedness and public safety, with calls for improved warning systems and infrastructure resilience in tornado-prone areas. Research from this tornado and the circumstances surrounding it has since contributed to greater understanding and forecasting capabilities for severe weather.
