Note: 17 tornadoes have been confirmed but not yet rated
Some tornadoes may be rated using the EF-scale because countries like Brazil (mostly São Paulo), Chile or Paraguay use partially or unofficially the Enhanced Fujita scale to rate some tornadoes more efficiently, however, to maintain consistency, this article primarily uses the traditional Fujita scale on the total count. In other cases of tornadoes rated using the EF-scale, their equivalent or the Fujita scale will be used instead.
Most South American tornadoes outside Brazil may lack information due to scarce or unreliable sources, even official confirmation, and some tornadoes may not be added to the list due to lack of information.
Similar to North America or Europe, South America also experiences a few tornadoes per year, Brazil being one of the countries with the highest incidence of tornadoes outside the regions traditionally known for such phenomena. According to a survey by the State University of Ponta Grossa (UEPG), between 1975 and 2018, a total of 581 tornadoes were recorded in the country, 411 of which occurred in the Southern Region, accounting for approximately 70% of all cases. In 2018, the PREVOTS platform was established to document severe weather events across Brazil. Upon completing five years of operation, a report indicated that between June 2018 and June 2023, 321 damage incidents caused by tornadoes were recorded, including waterspouts.[2] Most tornadoes in Brazil are associated with high-precipitation supercells, resulting in rain-wrapped tornadoes that are difficult to see. The annual average number of tornadoes in Brazil remains uncertain due to the country's less robust meteorological infrastructure compared to nations like the United States or Canada, and because of the low population density in the most tornado-prone areas. These factors contribute to underreporting, with many tornadoes being identified only months or even years after they occur. Recent estimates suggest a plausible average of 50 to 60 tornadoes per year, although this figure lacks official confirmation due to the aforementioned limitations.
