Question: he 1932 Deep South tornado outbreak was a deadly tornado outbreak that struck the Southern United States on March 21–22, 1932, the 2011 Super Outbreak was the largest, costliest, and one of the deadliest tornado outbreaks ever recorded, affecting the Southern, Midwestern, and Northeastern, of which country, and leaving catastrophic destruction in its wake?
Context: The 2011 Super Outbreak was the largest, costliest, and one of the deadliest tornado outbreaks ever recorded, affecting the Southern, Midwestern, and Northeastern United States and leaving catastrophic destruction in its wake.  The event affected Alabama and Mississippi the most severely, but it also produced destructive tornadoes in Arkansas, Georgia, Tennessee and Virginia, and affected many other areas throughout the Southern and Eastern United States.  In total, 362 tornadoes were confirmed by NOAA's National Weather Service (NWS) and Government of Canada's Environment Canada in 21 states from Texas to New York to southern Canada.  Widespread and destructive tornadoes occurred on each day of the outbreak, with April 27 being the most active day with a record of 218 tornadoes touching down that day from midnight to midnight CDT (0500 – 0500 UTC).  Four of the tornadoes were destructive enough to be rated EF5, which is the highest ranking possible on the Enhanced Fujita scale; typically these tornadoes are only recorded about once each year or less. The 2011 Hackleburg–Phil Campbell, Alabama tornado was a violent, long-track EF5 wedge tornado that devastated several towns in northern Alabama, United States, before tearing through the northern suburbs of Huntsville and causing damage in rural portions of southern Tennessee on the afternoon and early evening of April 27, 2011.  It was the deadliest tornado of the 2011 Super Outbreak, the largest tornado outbreak in United States history.  The tornado reached a maximum width of 1.25 mi and was estimated to have had peak winds of 210 mph .  The tornado killed 72 people, making it the deadliest tornado in Alabama history, and injured at least 145 others.  It was the deadliest tornado to strike the U.S. since the Udall, Kansas tornado of 1955 until the catastrophic tornado on May 22, 2011, which killed 158 people in Joplin, Missouri. The tornado outbreak sequence of May 21–26, 2011 was a deadly series of tornado activity across the Midwestern and Southern regions of the United States.  It was one of the largest tornado outbreaks on record.  Most of the tornadoes developed in a corridor from Lake Superior southwest to central Texas; isolated tornadoes occurred in other areas.  An especially destructive tornado destroyed one-third of Joplin, Missouri, resulting in 162 deaths and 1000 injuries.  The Joplin tornado is the deadliest in the US since April 9, 1947, when an intense tornado killed 181 in the Woodward, Oklahoma area.  Tornado-related deaths also occurred in Arkansas, Kansas, Minnesota, and Oklahoma.  Overall, the tornado outbreak resulted in 184 deaths, 6 of those non-tornadic, making it second only to the 2011 Super Outbreak as the deadliest since 1974, and the second costliest tornado outbreak in US history behind that same April 2011 outbreak, with insured damage estimated at $4–7 billion. The 1932 Deep South tornado outbreak was a deadly tornado outbreak that struck the Southern United States on March 21–22, 1932.  At least 36 tornadoes—including 27 killers and several long-lived tornado families—struck the Deep South, killing more than 330 people and injuring 2,141.  Tornadoes affected areas from Mississippi north to Illinois and east to South Carolina, but Alabama was hardest hit, with 268 fatalities; the outbreak is considered to be the deadliest ever in that U.S. state, and among the worst ever in the United States, trailing only the Tri-State Tornado outbreak in 1925, with 747 fatalities, and the Tupelo-Gainesville outbreak in 1936, with 454 fatalities.  The 1932 outbreak produced 10 violent tornadoes, classified F4 or F5 on the Fujita scale of tornado intensity, eight of which occurred in Alabama alone, and is surpassed only by the March 1952 tornado outbreak, with 11 violent tornadoes; the 2011 Super Outbreak, with 15; the 1965 Palm Sunday tornado outbreak, with 17; and the 1974 Super Outbreak, with 30. The Tornado outbreak of May 1968 was a significant and deadly tornado outbreak that struck most of the central and southern United States from May 15 to May 16, 1968.  Producing 46 tornadoes, the outbreak killed at least 72 people, including 45 in Arkansas alone.  The outbreak also produced two F5s in Iowa.  It was one of the deadliest tornado outbreaks in the United States since the 1960s and is one of the deadliest outbreaks in Iowa history. The Tornado outbreak sequence of May 1896 was a series of violent and deadly tornado outbreaks that struck much of the Central and Southern United States from May 15 to May 28, 1896.  It is considered one of the worst tornado outbreak sequences on record with tornado expert Tom Grazulis stating that the week of May 24–28 was "perhaps the most violent single week of tornado activity in US history".  There were four particularly notable tornado outbreaks during the two-week period.  It produced three F5 tornadoes as well as the third deadliest tornado ever in United States history.  A total of 484 people were killed during the entire outbreak sequence by at least 38 different tornadoes which struck Texas, Oklahoma, Kansas, Nebraska, Illinois, Missouri, Iowa, Kentucky, and Michigan. The late-April 1909 tornado outbreak was a deadly tornado outbreak that affected much of the central and Southern United States between April 29 and May 1, 1909.  Affecting particularly the Mississippi and Tennessee Valleys, it killed over 150 people, 60 of them in the U.S. state of Tennessee alone.  It was the deadliest known tornado outbreak to affect Tennessee until March 21, 1952, when 64 people died statewide.  To this day, the 1909 outbreak remains the second-deadliest on record in Tennessee—even the April 3–4, 1974 Super Outbreak and the February 5–6, 2008, Super Tuesday outbreak produced just 45 and 31 deaths each in the state. The tornado outbreak of April 14–16, 2011 was among the largest recorded tornado outbreaks in U.S. history, producing 178 confirmed tornadoes across 16 states and severe destruction on all three days of the outbreak.  A total of 38 people were killed from tornadoes and an additional five people were killed as a result of straight-line winds associated with the storm system.  The outbreak of severe weather and tornadoes led to 43 deaths in the Southern United States.  This was the largest number of fatalities in an outbreak in the United States since the 2008 Super Tuesday tornado outbreak.  However this outbreak was soon surpassed no less than two weeks later by the 2011 Super outbreak, which killed 324 people. The tornado outbreak of January 1–2, 2006, was one of the largest tornado outbreaks ever recorded in the month of January behind the January 2008 tornado outbreak sequence the January 12–13, 2006, tornadoes, the January 17–18, 1999 tornado outbreak, the January 21-23, 2017 tornado outbreak, and the January 21–23, 1999 tornado outbreak.  The outbreak affected much of the Central and Southern United States and produced 20 tornadoes.  The tornadoes caused considerable damage in the states of Kentucky and Georgia.  There were no tornado related fatalities and only minor injuries were reported. The Mid-June 1992 tornado outbreak was one of the largest tornado outbreaks on record, affecting portions of the Central United States from June 14 to June 18, 1992.  The outbreak began on June 14 when six tornadoes touched down in Colorado and Idaho.  Fifty-eight tornadoes were reported across portions of the Great Plains on June 15, and 65 more were reported over much of the central U.S. on June 16.  The 123 tornadoes that touched down on June 15–16 make that two-day span the 5th largest two-day tornado outbreak in U.S. history behind the 1974 Super Outbreak, the May 2004 tornado outbreak sequence, the April 14–16, 2011 tornado outbreak, and the 2011 Super Outbreak.  Twenty-eight more tornadoes touched down on June 17, and 13 more touched down on June 18, giving this outbreak 170 confirmed tornadoes.
