A deadly spring continued in the American South and Midwest as more tornadoes cut swaths of destruction through Missouri and Minnesota. The death toll in Joplin, Mo. was near 100 and expected to rise. As much as 30 percent of the town was damaged. In Minneapolis, a tornado killed one resident as it caused heavy damage and led to school closures and a curfew. The death toll from 2011 tornadoes stands now at 455, the deadliest year for tornados since 1953. -- Lane Turner ( 24 photos total
