2011 Joplin tornado
The 2011 Joplin tornado was a catastrophic EF5-rated multiple-vortex tornado that struck Joplin, Missouri, late in the afternoon of Sunday, May 22, 2011. It was part of a larger late-May tornado outbreak and reached a maximum width of nearly during its path through the southern part of the city. This particular tornado was unusual in that it intensified in strength and grew larger in size at a very fast rate. The tornado tracked eastward across the city, and then continued eastward across Interstate 44 into rural portions of Jasper County and Newton County. It was the third tornado to strike Joplin since May 1971.
1980 Grand Island tornado outbreak
The outbreak began on June 2, producing strong tornadoes in Iowa, Indiana, and Ohio, including one that struck the east side of Indianapolis. One fatality occurred near Crawfordsville, Indiana. Tornado activity continued on June 3, with additional strong tornadoes touching down in Pennsylvania, Maryland, West Virginia, and Nebraska. Over a span of three hours on the evening of June 3, 1980, a slow-moving supercell complex moving across Grand Island, Nebraska, spawned several tornadoes. The resulting outbreak was one of the most unusual in United States history: The supercells moved over the city at only ; of the seven tornadoes, three of them were anticyclonic; and the tornadoes did not move in a straight line, with most looping back over their own path at least once.
