100 years since the deadliest tornado in U.S. history, what's changed in weather forecasting?

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:

1. Advancements in meteorological technology: In 1925, there were no radar systems or satellites to help track severe weather. However, with the development of computer models, weather satellites, Doppler radar and weather balloons, we now have the ability to track storm systems in real time and provide more accurate forecasts for severe thunderstorms and tornadoes.

2. Warning systems: The use of emergency alert systems, tornado sirens and modern technologies like cellphones has greatly enhanced public awareness of severe weather. These advancements allow for timely warnings, giving people the information they need to take action and stay safe.

3. NOAA’s National Weather Service and Storm Prediction Center: With the establishment of National Weather Service offices and the Storm Prediction Center, meteorologists can now issue severe weather forecasts up to 48 hours in advance. This allows for more accurate and timely warnings, giving the public more time to prepare for potential severe storms and tornadoes.

4. Storm Spotter networks: Trained local storm spotters have become an essential part of storm tracking. By identifying severe weather firsthand, they provide valuable, real-time reports that help National Weather Service meteorologists verify tornado sightings and other severe weather events. This collaboration enhances the accuracy of warnings and improves response times, ultimately saving lives.

Could a disaster like this happen again?

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.
