Climatology

On average, about 40 tornadoes touch down in Louisiana each year.[2][better source needed]

Events

Pre-1950

edit
  • May 7, 1840 – A violent unrated tornado touched down in Concordia Parish, and tracked for 35 miles (56 km) through Natchez, Mississippi, killing at least 317 people, and injuring at least 109 others. The death toll was likely higher, as many enslaved people, potentially hundreds of them, were reportedly killed on plantations as the tornado moved through the parish, and were not counted on the official death toll. The tornado was the second-deadliest tornado in U.S. history.[3][4]

A completely destroyed home near Delhi following the F5 tornado that took place on February 21, 1971; multiple people were killed at this location
  • February 21, 1971 – During a larger tornado outbreak, a tornado touched down in Madison Parish, three miles to the southeast of Delhi, completely destroying multiple houses and other structures near the city, in the community of Waverly, and near the community of Transylvania at F5 intensity, before moving into Issaquena County, Mississippi. Eleven people were killed in Louisiana, with 18 others injured. The tornado traveled for 109.2 mi (175.7 km), had a peak width of 500 yd (460 m), killed 48 people, and injured 510 others. As of 2024, this is the only F5 tornado to have taken place in the state. In 1984 and 1993, tornado researcher Thomas P. Grazulis had assessed this tornado as an F4 in Louisiana, but had its rating revised in a 2001 assessment to accept the official F5 rating.[5]

The first EF2 tornado moved through the community of Four Forks on the afternoon of December 13, destroying numerous manufactured homes, damaging several trees in the area, killing two people, and injuring another two. Another tornado, rated EF3, moved through northern portions of Farmerville that evening, which significantly damaged multiple houses, trees, and apartments, destroyed several outbuildings and mobile homes, and injured 14 people. On the morning of December 14, another EF2 tornado moved through southeastern portions of New Iberia, destroying multiple mobile homes, damaging numerous houses, vehicles, and businesses, including a hospital which sustained major roof and interior wall damage, and injuring 16 people. An EF2 tornado also struck the communities of Killona and Montz, destroying numerous mobile homes, damaging trees in the area, killing one person, and injuring eight others. Another EF2 tornado impacted Marrero, Harvey, Gretna, and Arabi near New Orleans later that afternoon, damaging many homes, businesses, and trees in its path, and injuring six people.

  • January 2, 2023 – Amid a larger three-day tornado outbreak taking place across the southern U.S., seven tornadoes touched down within Louisiana, two of which were rated EF2. The first EF2 tornado was a 1.1-mile-wide (1.8 km) tornado that severely damaged multiple houses, snapped large trees, and injured three people east of Jonesboro, and the second EF2 tornado knocked down several large electrical-transmission towers and destroyed an outbuilding to the south of Haile.[8][9]
  • January 24, 2023 – Seven tornadoes affected the state during a tornado outbreak that was taking place in Texas and Louisiana, two of which were rated EF2. After causing EF2 damage west of Orange, Texas, a tornado crossed the state line into western Calcasieu Parish, where it caused tree damage, and destroyed multiple mobile homes, RVs, and outbuildings as it impacted the Nibletts Bluff Park near Vinton. The tornado injured two people. An EF1 satellite tornado also occurred to the south of the EF2 tornado, which caused damage to more trees and mobile homes before merging into the previous tornado. After the first EF2 tornado lifted, the second EF2 tornado touched down in the northern part of the parish and moved northeast into Beauregard Parish, near the community of Gaytine, where it significantly damaged several homes, outbuildings, and trees.[8]

  • April 9–10, 2024 – During a three-day severe weather outbreak which produced 35 tornadoes along the Gulf Coast, 16 tornadoes touched down within Louisiana, including two EF2 tornadoes. As a quasi-linear convective system (QLCS) moved into the state, twin EF1 tornadoes took place near Grand Lake, and as the tornadoes dissipated, an EF2 tornado touched down on the eastern edge of McNeese State University, damaging homes, other buildings, trees, and power lines in the area. Later in the day, two EF1 tornadoes moved near St. Francisville, including one which traveled for 32.4 mi (52.1 km) and was 880 yd (800 m) wide, causing large amounts of tree damage along its path. Multiple tornadoes also impacted areas near Slidell, including an EF2 tornado which impacted the southern portions of the city, causing major damage to homes and businesses in the area, damaging power poles and trees, and injuring several people.[8]
