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 (1,500sqmi).[7][8][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 8:30p.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 (3,300ft) and its route exceeded 10 kilometres (6.2mi). 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 (1.2mi) long and 250 metres (820ft) 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.[11][2]
Possible tornado from a bow-echo mesovortex, estimated an F3, severely destroyed 90% of the town of Villa del Rosario (Córdoba), causing 2 deaths. It's likely that this event was an extreme downburst.[12] A tornado, rated F1 or F2, hit the city of Chivilcoy, causing much destruction, where 1 death was reported.[13]
An F2 tornado occurred in the city of Santiago del Estero, causing trees to fall and destroying homes, possibly having a classification higher than F2. It's also possible that this event was a downburst.

F2/EF2
Tornado Outbreak in Southern Brazil – May 8–9, 2025
Between May 8 and 9, a strong cold front advanced through southern Brazil and collided with a mass of hot, humid air from the north, causing severe weather conditions. The meeting of these systems resulted in heavy rain, strong winds, and at least five confirmed tornadoes in the southern region. On the 8th, two tornadoes hit the rural area of Bossoroca, in Rio Grande do Sul, between the late afternoon and early evening.There were no reports of injuries or significant damage. On the 9th, a tornado(F2) passed through Erval Grande, also in Rio Grande do Sul. With winds exceeding 150km/h, it caused damage to several rural properties, knocked down trees and power lines, and left some people injured. In Santa Catarina, two tornadoes were also recorded. One of them hit the city of Palmitos, destroying more than 50 rural properties and causing trees to fall. causing a fatality. The other tornado occurred in Santo Amaro da Imperatriz, where houses were damaged and trees were knocked down, but there were no injuries.[24][25][26][27][22]
Strong winds hit the municipality of Tenjo, Cundinamarca, leaving 31 homes without roof and several fallen trees on vehicles and power cables, as well as a service station, two restaurants and a school affected.

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.
An 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 extremely intense ground scouring occurred. This tornado wasn't discovered until decades later, by LANDSAT satellites.[35] It's presumed that this tornado reached F4-F5 during its course.[36]
On the evening of April 8, a strong tornado struck the small village of San Javier, Paraguay, located just north of San Ignacio.
