On March 18, 1925, one of the deadliest tornadoes in U.S. history struck southeast Missouri, southern Illinois, and southwest Indiana. The Tri-State Tornado, with its vast size, rapid movement and long track, caused hundreds of deaths and left thousands injured.

The tornado stayed on the ground for over 3 1/2 hours and carving a 219-mile path resulting in 695 fatalities and thousands of injuries.

As we reflect on this historic event, what advancements have been made in forecasting and meteorology? Is it possible for a similar disaster to occur again?

Here are some ways that forecasting and meteorology have changed since that tragic day:

While a tornado like the Tri-State Tornado could technically happen again, advancements in meteorology, forecasting, and public safety make it highly unlikely that such an event would result in the same number of deaths. 

The Tri-State Tornado was an extreme event, and while large, long-track tornadoes still occur, modern technology allows for better detection, earlier warnings, and more effective public response.

Overall, while the Tri-State Tornado remains a tragic event, it also marked a turning point that contributed to the ongoing improvements in meteorology and weather forecasting, ultimately saving many lives today.
