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.
March 1997 tornado outbreak
Another supercell north of the main storm produced several tornadoes north of Little Rock and Jonesboro. Among the towns affected was Marmaduke, which was also affected by an F3 tornado during the April 2, 2006 tornado outbreak.
11 counties across Arkansas were declared federal disaster areas by then-US President Bill Clinton for tornadoes while two others in were for flooding. Seven other counties in Tennessee were also declared disaster areas due to tornadoes. It was considered the worst tornado outbreak since the Palm Sunday tornado outbreak of 1994, which killed 42 across Alabama and Georgia. In Kentucky, then-governor Paul E. Patton had initially declared 120 counties a state of emergency and deployed about 1100 National Guard troops to the flood-stricken regions. In Indiana, the Ohio River overflow its banks due to record rains. All 13 counties along the river between Evansville and Cincinnati were also declared disaster areas. In West Virginia, then-Governor Cecil Underwood declared state of emergencies for 14 counties, and 16 were later declared disaster areas as over 4 000 homes and other structures were damaged by the flooding.
