This is the second time in seven years that a meteotsunami has hit the region. In 2009, Florianópolis was also affected by a tsunami-like wave.
Advert climatic conditions created a rare weather phenomenon in Southern Brazil: a meteorological tsunami, or more simply, a meteotsunami. It consists of a tsunami-like wave event related to air pressure conditions. At least 20 cities were hit by the storms, which destroyed thousands of homes and killed one child.
In the municipality of Balneário Rincão (located 186km from Florianópolis, the state capital of Santa Catarina), a giant wave hurt dozens of people and destroyed cars and buildings along the coast. Civil defense officials were sent to rescue people dragged to the sea. Wind speed hit the 100km/h mark.
The coastal city of Tubarão was affected the most. A falling tree killed a 7-year-old child, and two men who were sailing on Sunday afternoon were reported missing. In low-income neighborhoods, 90 percent of the houses had their roofs destroyed.
According to local officials, more than 140,000 homes had their energy supply interrupted.
