The outbreak of tornadoes in Buenos Aires in 1993 was an outbreak (QLCS type) of more than ≥100 tornadoes that affected the southern part of Buenos Aires. It happened between the night of Tuesday, April 13 and 14. Between the hour 20 and 24, an extraordinary system of severe convective thunderstorms affected the localities of Trenque Lauquen, Pehuajó, Hipólito Yrigoyen, Carlos Casares, Bolívar, Daireaux, General Lamadrid, Olavarría, Tapalqué, Azul, Laprida, Benito Juárez, Tandil, Necochea, Lobería, Balcarce, General Alvarado and General Pueyrredon. The most affected localities were Henderson (F3), Urdampilleta (F3) and Mar del Plata (F2). This succession of tornadoes had intensities from F0 to F3 and produced severe damage along strips oriented from northwest to southeast. The local area affected was greater than 4,000 square kilometres (1,500 sq mi).[6][7][2]
An F3 tornado left thousands of homes destroyed. Also 1000 trees and 150 ceilings were severely damaged. The tornado lasted 24 minutes and affected three neighborhoods, making it the longest-lasting tornado in the Southern Hemisphere.[2]
The tornado outbreak in Argentina in 2009 was an outbreak of 28 confirmed tornadoes that occurred on the night of September 7 and violently affected the northeast of Misiones and Southern Brazil. The event reached and destroyed several localities. It is estimated that at least 17 people died and more than 250 people were injured. Many other cities were destroyed and damaged by tornadoes.
Around 8:30 p.m. on September 7, a supercell produced an F4 tornado that destroyed the city of San Pedro. The event was accompanied by a violent storm of hail and rain. The tornado lasted approximately 5 minutes. It had a width of 1 kilometre (3,300 ft) and its route exceeded 10 kilometres (6.2 mi). At least 11 people died and another 100 people were injured in San Pedro. The amount of tornadoes that affected the area is comparable to the size of the province of Tucumán in Argentina. It is estimated that a total of 17 people died and just over 250 injured. Regardless of tornadoes, other adverse storm phenomena also produced damage in a large area. Reconstruction of villages, towns and cities took several years and it was noted that some could never be reclaimed.[2]
On January 26, 2011, a tornado formed over Laboulaye Córdoba, leaving 60 homes damaged. There were only six injuries. The trail of destruction of the tornado was 2 kilometres (1.2 mi) long and 250 metres (820 ft) wide. The tornado was rated F2.[citation needed]
On April 4, 2012, Greater Buenos Aires was hit by a very severe thunderstorm and a derecho, which produced 5 tornadoes with F1 and F2 intensities. Seventeen fatalities were reported in various locations.[10][2]

Hundreds of municipalities from these three states were affected by intense hailstorms, violent downbursts (≥150 km/h) and several devastating tornadoes. The municipality of Guaraciaba (Santa Catarina) was devastated by an F4 tornado. The same supercell also produced more three F3 tornadoes that caused devastation in forests, near Guaraciaba. Intense tornadoes also occurred in the municipalities of Aceguá (FU), Caiçara (FU), Victor Graeff (FU), Macieira (FU), Caçador (FU), Salto Veloso (FU), Santa Cecília (FU), Primeiro de Maio (FU), etc. Another unrated strong tornado was also confirmed by IPMET in Echaporã and Platina (state of São Paulo).[11][12][15]

High-precipitation supercell thunderstorms produced by a low pressure system in Argentina produced tornadoes in Southern Brazil and in the province of Misiones (Argentina). Two high-end EF3/EF2 (respectively) tornadoes produced by the same supercell, tracked through several municipalities (Ciríaco, Tapejara, Água Santa, Sarandi) of Rio Grande do Sul, causing two deaths and leaving more than a thousand damaged homes. 24 municipalities were affected by severe thunderstorms and more than 2,630 homes were affected. Another tornado struck Nova Conquista, a locality in the municipality of Chiapetta (EFU), but caused no damage.

It is visualized that in the distance a very strong storm develops that had the ability to create the eddy, which fortunately did not cause damage due to occur in the open field.
A extremely large, long-tracked tornado with extreme multi-vortex activity, left a gigantic scar over rural/forested areas of eastern Paraguay. Extreme forest damage and ground scouring occurred. This tornado wasn't discovered until decades later, by LANDSAT satellites.[20] It's presumed that this tornado reached F4-F5 during its course.[21]
