A powerful tornado tore through Rio Bonito do Iguaçu, Paraná, on Friday, November 7th, leaving behind a level of destruction rarely witnessed in southern Brazil. According to Paraná’s Civil Defense, at least six fatalities have been confirmed—four of them in Rio Bonito do Iguaçu—and approximately 750 people sustained injuries. Entire neighborhoods were leveled, with dozens of families losing their homes and facing displacement.

Videos rapidly circulated on social media, capturing dramatic scenes of roofs being torn away, walls collapsing, and torrential rainfall illuminated by relentless lightning. The tornado struck with little warning, unleashing intense winds and frequent lightning. The violent storm knocked out power and water supplies throughout the region. Emergency crews worked through the night, rescuing trapped residents and beginning the arduous task of debris removal.
This event marks one of the most severe tornado outbreaks to hit Paraná in recent years. Damage extended well beyond Rio Bonito do Iguaçu, affecting neighboring cities and even some communities in Santa Catarina, such as Dionísio Cerqueira, where residents documented extensive wind damage.

In response, the government of Paraná promptly declared a state of public calamity for Rio Bonito do Iguaçu and surrounding areas. On Saturday, Governor Ratinho Junior submitted a bill to the State Legislative Assembly to expedite financial relief for affected families through the State Fund for Public Calamities (Fecap).
If approved, the legislation will provide up to R$ 50,000 (about US$ 8,700) in direct aid to families whose homes were destroyed, eliminating intermediaries and minimizing wait times.
“The losses are significant and the damage is critical. Residents require immediate assistance from the state,” stated Colonel Fernando Schunig, chief of Paraná’s Civil Defense. “Our primary objective is to deliver urgent support and accelerate recovery efforts.”
The Assembly is scheduled to convene in two special sessions on Sunday to deliberate and vote on the measure.
Governor Ratinho Junior visited the affected area Saturday morning, pledging emergency resources to repair essential infrastructure, including roads, bridges, schools, daycare centers, and health clinics that sustained severe damage or total destruction.
“This new law allows us to act quickly and deliver direct assistance to families,” the governor said.
Currently, teams from Cohapar, CREA, and municipal governments are conducting damage assessments to prioritize response actions.
Preliminary meteorological analyses indicate that the tornado developed due to an extremely unstable atmosphere, the presence of a strong cold front, intense wind shear, and high humidity levels. Experts estimate wind speeds exceeded 180 km/h (112 mph), classifying the tornado between EF2 and EF3 on the Enhanced Fujita scale.
Tornadoes of this magnitude were once uncommon in southern Brazil, but their frequency and intensity are increasing. Each spring brings more severe storms, and the incidence of tornadoes and windstorms appears to be on the rise annually.
With hundreds of homes destroyed, authorities are working urgently to establish temporary shelters and are considering renting local hotels to accommodate families requiring special support, including individuals with disabilities or those with limited mobility.
“Many residences have been completely demolished. We are committed to providing safe, adequate shelter as we work toward reconstruction,” said Colonel Schunig.
Cities such as Laranjeiras do Sul and Quedas do Iguaçu are providing refuge for those who have lost everything. Meanwhile, Civil Defense teams remain on the ground, clearing debris and working to restore habitability in the most affected areas.
In Curitiba, donation centers have been set up to collect food, clothing, blankets, and hygiene supplies. The local community is mobilizing, echoing the collective response seen after last year’s floods in União da Vitória and São Mateus do Sul.
Since 2023, the State Fund for Public Calamities has allocated more than R$ 61.2 million to assist 102 municipalities in responding to natural disasters—including tornadoes, floods, frost, and drought. The fund’s structure enables rapid, direct allocation of resources to areas in need, bypassing bureaucratic hurdles.
This tornado serves as a sobering reminder: southern Brazil is increasingly vulnerable to extreme weather events. As climate patterns shift and storms grow more severe, tornadoes—once rare—are becoming a persistent hazard. Improved forecasting, swifter warnings, and more resilient urban planning will be essential to mitigate the impact of future disasters.
