MANCHESTER, S.D. (AP) – Residents of the former South Dakota town of Manchester will be gathering at the site Monday evening for an informal potluck commemorating the 10th anniversary of the F4 tornado that destroyed the community. The Manchester twister was the worst of 67 tornadoes that developed in eastern South Dakota on June 24, 2003 – a date that became known across the state as “Tornado Tuesday.” No one was killed, but three of Manchester’s six residents were injured. Loretta Yost was visiting a cousin when her farmstead north of town was destroyed. Their house, barn, shop, chicken house and two grain bins were all gone. Her husband’s Chevrolet pickup was dangling against a tree. Yost says it was unreal that a storm could do away with their home of nearly 25 years
