F3 tornado in Paraná, Brazil
On November 7, 2025, an intense[1] tornado devastated the municipality of Rio Bonito do Iguaçu in Paraná, Brazil, killing six people, injuring over 784 others,[2] and causing widespread damage. The tornado was rated as an F3 on the Fujita scale.[1][3][4][note 1]
Meteorological synopsis
[edit]
According to Simepar and MetSul Meteorologia, the tornado was caused by the interaction between a mass of warm, humid air coming from the north of the country and a strong cold front advancing through the south, driven by an extratropical cyclone. The atmospheric conditions favored the formation of a supercell, a set of clouds characterized by an ascending, rotating air current, which can produce tornadoes, hail, and severe storms under ideal conditions.[6][7]
The warm air that was over southern Brazil, coming from the Amazon rainforest, increased thermodynamic instability, which was also intensified by the sharp drop in temperature, enabling the formation of other storms in the region, including at least three other tornadoes in the neighboring state of Santa Catarina.[6][8] A tornado also struck the nearby city of Guarapuava, killing one person, but authorities could not verify whether this was a separate cell from the one that struck Rio Bonito do Iguaçu.[9]
In addition to the squall line produced by the cyclone, other determining factors for the formation of the tornado were low level jets directed westward across Santa Catarina and Paraná, increasing wind shear and thus favoring tornadogenesis.[6][7]
The tornado caused widespread destruction in the urban and rural areas of the municipality. According to the governor of Paraná, Ratinho Júnior, about 90% of the homes in Rio Bonito do Iguaçu were partially or totally destroyed.[10]
The tornado killed at least six people and injured 750 others. Among the victims was a 14-year-old girl who died from her injuries after the house where she was sheltering with her family collapsed.[11][12] A supermarket also collapsed, trapping multiple people under debris.[13] About 1,000 people were displaced.[14]
The tornado had widespread national and international repercussions, being described by meteorologists as one of the most intense ever recorded in Paraná. MetSul highlighted that the occurrence of an F3 tornado in southern Brazil is a rare event, comparable only to a few documented cases in recent decades.[6]
Teams from Civil Defense, the Paraná Fire Department and the Brazilian Army were deployed to the municipality in the first hours after the disaster. Searches for victims were carried out among the rubble throughout the weekend. The state government sent trucks with food, blankets, and drinking water, as well as equipment to restore electricity.[1]
Temporary shelters were set up in gyms and schools in the region. Nearby hospitals, such as those in Laranjeiras do Sul and Guarapuava, received seriously injured people. Governor Ratinho Júnior declared a state of emergency and announced financial support for the reconstruction of the most affected areas.[10]
Initial estimates pointed to losses in the tens of millions of reais, although the exact amount has not yet been officially released.[11]
Governor of Paraná Ratinho Júnior led an emergency meeting at the Central Fire Department Headquarters in state capital Curitiba regarding response to the disaster,[15] stating “it is a unique catastrophe in the history of Paraná”.[16]
President of Brazil Luiz Inácio Lula da Silva sent his cabinet ministers to aid in the relief efforts.[17]
