February 21–22
A deadly tornado outbreak struck portions of the Lower Mississippi River Valley and the Southeastern United States on February 21–22, 1971. The two-day outbreak produced at least 19 tornadoes, and probably several more, mostly brief events in rural areas;[6][7] killed 123 people across three states; and "virtually leveled" entire communities in the state of Mississippi.[8] Three violent, long-lived tornadoes—two of which may have been tornado families[9]—in western Mississippi and northeastern Louisiana caused most of the deaths along 300 miles (483 km) of path.[7] One of the tornadoes attained F5 intensity in Louisiana, the only such event on record in the state.[10][11] The outbreak also generated strong tornadoes from Texas to Ohio and North Carolina. The entire outbreak is the second deadliest ever in February, behind only the Enigma tornado outbreak in 1884 and ahead of the 2008 Super Tuesday tornado outbreak. February 21 was the fourth-deadliest day for tornadoes in Mississippi on record.[7] At one point, the National Weather Service WSR-57[12] radar in Jackson, Mississippi, reported four hook echoes, often indicative of tornado-producing supercells, simultaneously.[7]
