"On April 27, 2011, a series of devastating tornadoes struck the southeastern United States. This tornado event was the third deadliest in the country since systematic tornado record keeping began in 1950. With 316 fatalities (31 in Mississippi, 234 in Alabama, 32 in Tennessee, 15 in Georgia, and 4 in Virginia), it follows only the 1974 Super Tornado Outbreak (368 deaths) and the 1965 Palm Sunday Tornado Outbreak (337 deaths). Damages from this tornado episode resulted in over $4.2 billion in property damage and more than 2,400 injuries. The National Weather Service (NWS) formed a Service Assessment Team to evaluate its performance. To strengthen NWS relationships with other federal agencies involved with disaster work, for the first time this assessment had a co-leader from the Federal Emergency Management Agency. The team interviewed staff and reviewed products from the Storm Prediction Center (SPC), Weather Forecast Offices at Memphis and Morristown, TN, Jackson, MS, Huntsville and Birmingham, AL, and Peachtree City, GA. The team gathered feedback from partners and users of NWS products including media outlets, Emergency Managers at the state and local level, first responders, and the public. One of the team's tasks was to assess societal impacts of this event."
