A powerful tornado struck the city of Chapecó in southern Brazil on Wednesday, November 4, 2026, bringing destructive winds, damaging buildings and disrupting airport operations. The severe weather caused significant damage to infrastructure, leaving residents facing an emergency response as authorities began assessing the destruction. According to local reports, wind gusts in Chapecó reached approximately 126 kilometres per hour. The powerful winds damaged residential and commercial structures, ripped away roofing materials and affected important infrastructure, including Serafim Enoss Bertaso Airport. The damage at the airport was serious enough to force the suspension of flight operations for an indefinite period. Airport authorities began inspecting the affected infrastructure and advised passengers to contact their airlines before travelling to the terminal. The situation was not limited to Chapecó. Santa Catarina's Civil Defence also confirmed a second tornado in the nearby municipality of Xanxerê, making the weather event particularly concerning for communities across the western part of the state. Emergency responders assisted more than 400 families in Chapecó following the destruction. The incident has brought renewed attention to the Brazil Tornado situation, with authorities monitoring weather conditions and assessing the damage.

Chapecó Tornado Causes Widespread Damage Across the City

The tornado moved through Chapecó during the morning hours of November 4, creating dangerous conditions for residents and businesses. Strong rotating winds affected several parts of the city, damaging buildings and pulling roofing materials away from structures. Metal installations and other exposed infrastructure were also affected by the force of the storm. Neighbourhoods including Seminário and Esplanada were among the areas reported to have suffered damage. Several properties experienced roof damage, while trees and other structures were affected by the powerful winds. The intensity of the weather event was reflected in the meteorological readings. While a local Civil Defence weather station recorded gusts of around 92.9 km/h, another monitoring station operated by Brazil's National Institute of Meteorology (INMET) recorded a maximum gust of approximately 126 km/h in the city. The difference in readings reflects measurements taken at different locations. However, both indicate the strength of the storm that affected the region. The authorities began assessing the affected areas to determine the full extent of the destruction. Drone-based surveys were also planned to help identify damaged structures and examine the path of the tornado.

Chapecó Airport Damaged, Flight Operations Suspended

One of the most significant impacts of the tornado was reported at Serafim Enoss Bertaso Airport in Chapecó. The powerful winds damaged several sections of the airport infrastructure, including parts of the passenger terminal and aircraft hangars. Metal roofing sheets were torn away, steel structures were twisted and glass windows were broken. The damage disrupted normal airport operations and forced authorities to suspend arrivals and departures indefinitely while technical inspections were carried out. The airport concessionaire, Voe Xap, confirmed that its teams were examining the affected infrastructure and taking steps to assess the damage before operations could resume. Passengers were advised not to travel to the airport without checking the latest information. Travellers were also asked to contact their respective airlines directly regarding cancellations, alternative flights, rescheduling and other travel arrangements. During the storm, an aircraft belonging to Azul Linhas Aéreas was preparing for departure but had to stop the take-off process because of the sudden deterioration in weather conditions.

Second Tornado Confirmed in Nearby Xanxerê

The severe weather situation became even more concerning after Santa Catarina's Civil Defence confirmed another tornado in Xanxerê, a municipality located approximately 44 kilometres from Chapecó. According to meteorological observations, the first tornado was recorded in Chapecó at around 10:30 a.m. local time on November 4. The second was identified in Xanxerê at approximately 10:48 a.m., less than 20 minutes later. Weather radar analysis played an important role in confirming both events. Authorities examined signs of rotating winds and debris lifted into the atmosphere, which helped distinguish the tornado activity from ordinary strong winds. Xanxerê also experienced considerable damage. Reports described damaged houses, fallen trees, affected industrial structures and vehicles overturned by powerful winds. At least 200 homes in Xanxerê were reported to have suffered damage in the initial assessment, with emergency teams distributing protective coverings to affected residents.

More Than 400 Families Receive Emergency Assistance

Emergency services were deployed across Chapecó to help residents affected by the destructive weather. According to the Santa Catarina Military Fire Brigade, more than 400 families received assistance following the storm. Many of the reported emergencies involved damaged roofs and fallen trees. Rescue and emergency personnel worked to respond to calls from affected neighbourhoods, assist residents and address dangerous situations caused by the storm. The immediate priority was to help families whose homes had been damaged and reduce the risks created by unstable structures, fallen trees and other debris. Authorities also began collecting information about damaged properties and assessing what assistance affected households might require. The impact extended beyond Chapecó. A wider sequence of storms had affected 58 municipalities across Santa Catarina, with an initial state assessment reporting 1,438 affected homes. Four municipalities had also declared emergency situations following weather-related destruction. These figures indicate that the tornadoes were part of a broader period of severe weather affecting the state rather than an isolated incident in one city.

Why Did Two Tornadoes Form in Santa Catarina?

The tornadoes developed during a period of intense atmospheric instability affecting southern Brazil. A strong storm system moved across western Santa Catarina, bringing heavy rain, lightning and powerful wind gusts. Meteorological radar observations detected rotating wind patterns associated with the development of the two tornadoes. Santa Catarina's Civil Defence had issued a severe weather warning approximately 15 minutes before the tornadoes were recorded in Chapecó and Xanxerê. Such weather systems can develop rapidly, making it difficult for residents to respond once dangerous conditions begin. A tornado is a rapidly rotating column of air extending from a thunderstorm cloud towards the ground. Depending on its intensity and path, it can damage buildings, uproot trees, overturn vehicles and disrupt essential services. Unlike ordinary strong winds, tornadoes can produce concentrated areas of severe destruction because of their rotating wind patterns. Meteorological teams continued examining radar information, weather station readings and damage reports to understand the intensity and path of the phenomena.

Authorities Issue Safety Advice as Weather Monitoring Continues

Following the destruction, authorities urged residents to remain cautious and follow official weather warnings. People were advised to stay inside secure buildings during strong winds and avoid standing near windows, glass doors or weak structures. Residents were also warned against taking shelter beneath trees, electricity poles, roadside signs or structures that could collapse during severe weather.

Other important safety recommendations included:

• Avoid travelling through flooded roads and areas affected by fallen trees.

• Stay away from damaged electrical wires and exposed power infrastructure.

• Keep away from buildings with unstable roofs or damaged structural components.

• Move to an interior room during severe winds, away from windows.

• Follow updates issued by Civil Defence and local emergency services.

• Contact emergency responders if a building becomes unsafe or someone requires assistance.

Authorities also planned further inspections to identify damaged properties and determine the support needed by affected communities. Weather officials warned that unstable conditions could continue across parts of Santa Catarina, making it important for residents to remain alert to new forecasts and official advisories.

Brazil Tornado: What Happens Next in Chapecó?

The immediate focus in Chapecó remains on emergency assistance, infrastructure inspections and restoring essential services. At the airport, technical teams must assess the damage before a decision can be made about the resumption of flight operations. Passengers are being advised to rely on airline announcements rather than travel to the terminal without confirmation. For residents, the priority is repairing damaged homes, receiving emergency supplies and ensuring that affected neighbourhoods are safe. The confirmation of a second tornado in Xanxerê has also increased concern across the region. Authorities are continuing to examine the damage in both municipalities and monitor weather developments. The events of November 4 demonstrate how quickly severe storms can disrupt daily life, damage critical infrastructure and leave hundreds of families needing assistance.
