A harrowing history: 50 years since the 1974 Super Outbreak

50 years ago today, the South and part of the Ohio and Tennessee Valleys were devastated by one of the most significant weather events in U.S. history. Infamously known as the 1974 Super Outbreak, which lasted from April 3-4, 1974, the Outbreak was the first on record to produce more than 100 tornadoes in a 24-hour period. The onslaught resulted in the loss of 335 lives and $600 million in damages.

The Super Outbreak wrought havoc across 13 states, producing the second-largest outbreak of tornadoes on record, including seven EF-5 tornadoes - the most in a single day. The outbreak included the disastrous Xenia, Ohio, tornado.

To preserve the history of the Outbreak, NOAA's National Weather Service (NWS) collected personal accounts of some of the survivors of these devastating tornadoes. (Some of the accounts mention loss of life and other graphic descriptions, and may be upsetting to some readers).

The neighborhood across from the school was ripped to shreds... many houses now nothing more than foundation. The high school and the gymnasium were destroyed and the elementary building had its roof ripped off, but the first thing you saw of the school was the enormous hole in the wall where the multi purpose room was.

Having been in that room just 90 minutes prior, it amazed me that so much damage could happen so quickly.

A modern era of forecasts, warnings and public education

This tragic event and loss of life spurred several improvements in public education and awareness, and served as the catalyst for a major overhaul of NWS: The Modernization and Associated Restructuring (MAR). Volumes 1 and 2 of the MAR were written in the 1980s and implemented in the 1990s to vastly modernize the agency's observational infrastructure and the NWS field office structure.

The effort also added new degree requirements for NWS meteorologists and hydrologists. Advanced staff training in these modernized systems ensured more rapid detection of storms and led to the modern era of delivering timely forecasts and warnings to the public.

Technologies introduced during this time included NOAA Weather Radio expansion, Next Generation Radar and more.

These advancements provided the tools that meteorologists needed to more quickly make quick decisions, prepare forecasts and warnings and disseminate crucial weather information to the public.

Forecasting for the future: A holistic approach

Today, NWS continues to improve and innovate as we transform our services to meet growing societal needs for weather, water and climate information, forecasts, services and decision support. NWS aims to become a more nimble, flexible and mobile agency, working in-person on the front lines with public safety officials as they make important, lifesaving decisions for their communities.

Introduced in 2023, the National Weather Service's strategic plan, Priorities & Action Strategies for the Future, defines this modern transformation under three overarching priorities of Our People, Our Infrastructure and Our Future. Initiatives are being developed today that will: (1) Fully support the NWS workforce, with a focus to eliminate employee burnout and ensure that NWS reflects the people in the communities we serve; (2) Repair and modernize the agency's critical infrastructure so that it is resilient and reliable; and (3) Position the agency for success into the future.

Post your #SafePlaceSelfie!

As we remember the tragic events of the 1974 tornado Super Outbreak, it's a fitting time to pause and identify a safe, secure space to go to when tornadoes threaten your home, office or wherever you are.

Not sure how to identify your "safe place?" Check out our #SafePlaceSelfie campaign page for ideas. Then, take a picture of yourself in a place where you can shelter safely during an extreme weather event, post it to @NWS social media and use the hashtag #SafePlaceSelfie.

Dangerous and damaging extreme weather can happen any time, anywhere. Wherever you are, know your safe place so you can make quick decisions that could save your life!
