During strong storms that hit the South Region of Brazil on June 30, 2020, cities registered winds of more than 120 km/h in several points of Santa Catarina, Rio Grande do Sul and Paraná. This phenomenon is known as bomb cyclone, because in this region a sharp drop in atmospheric pressure was recorded over a period of 24 hours, causing cyclones that were not predictable by meteorologists.[4]
Until 9pm BRT on the 30th, three deaths were registered as a result of cyclones in Santa Catarina, one in the city of Chapecó, one in Santo Amaro da Imperatriz and one in Tijucas, besides one death in Rio Grande do Sul, in the city of Nova Prata.[1][2]
