RIO BONITO DO IGUAÇU, Paraná – A violent, F2-class tornado tore through the heart of Rio Bonito do Iguaçu on Friday, November 7, leaving a trail of destruction, claiming five lives, and injuring approximately 130 people in one of the most severe weather events to hit southern Brazil this year.
A Community in Ruins
Preliminary assessments from local authorities and Paraná Civil Defense paint a picture of near-total devastation across the urban area. An estimated 80% of the town’s structures sustained damage or were completely destroyed, affecting nearly all of the municipality’s 14,000 residents. The tornado’s fury collapsed a supermarket, uprooted countless trees and power poles, and brought down masonry walls, rendering streets impassable. The town’s essential services, including electricity and water supply, were severely disrupted.
In the aftermath, a massive multi-agency response is underway. Firefighters, police, and medical teams from neighboring municipalities have joined local volunteers in a desperate race against time to clear debris, search for survivors, and provide emergency medical care.
State of Emergency Declared
Paraná Governor Ratinho Júnior convened an emergency meeting at the Central Fire Department headquarters in Curitiba on Friday night to coordinate state relief and damage assessment measures.
“We already knew that we would face a difficult moment,” Governor Ratinho Júnior stated, “but we never imagined a tornado that could cause all this devastation.”
With the number of displaced families rising rapidly, the municipality is preparing to open official donation channels. Temporary shelters have been established in local schools and community centers to house those who have lost their homes.
The Science Behind the Storm
Meteorologists from Simepar (Sistema de Tecnologia e Monitoramento Ambiental do Paraná) confirmed the event was a strong F2 tornado on the Fujita scale. The tornado formed along a powerful line of instability, fueled by an extreme temperature clash.
The conditions were primed for a severe storm. On the same day, the nearby city of Guarapuava recorded a scorching 34.5°C (94.1°F)—its highest November temperature since records began in 2001. This hot, humid air from the north collided with a mass of cold air advancing from Argentina. This dramatic thermal contrast, combined with high atmospheric instability, created the perfect conditions for the supercell thunderstorms that spawned the tornado. Simepar estimated the tornado’s wind speeds reached a devastating 180 to 250 km/h (110-155 mph).
As search-and-recovery efforts continue in Rio Bonito do Iguaçu and surrounding rural areas, the state remains on high alert, with reports of severe hail and heavy rainfall affecting other parts of Paraná.
