TUSCALOOSA, Ala. (AP) — Students at Harvard University are getting a lesson about the Alabama tornado outbreak of 2011. Tuscaloosa Mayor Walt Maddox will speak at Harvard's Kennedy School of Government on Wednesday. Maddox will discuss the city's response to the massive EF-4 twister that hit the city on April 27, 2011. The tornado killed more than 50 people and destroyed or damaged thousands of structures, but Maddox received generally positive reviews for his handling of the disaster. He was re-elected earlier this year. An announcement from the school says Maddox will discuss how a restructuring of the area's emergency management system before the tornado helped in the aftermath of the storm. Harvard is playing host to a conference for more than two dozen newly elected mayors this week.
