Despite the excellent warnings, the loss of life was exceptionally high, and not acceptable.
Using data from social science research and many hours talking with those affected by the tornadic storms, much has been learned about what worked, and what didn't work on April 27, 2011. As media meteorologists, we must learn from this outbreak and apply the knowledge to our work in future tornado events to save lives. Being on traditional television and radio, and using social media isn't enough; you have to use it correctly, and in a way that reaches the most people in a timely fashion.
