The acting governor of Rio Grande do Sul, Gabriel Souza (MDB), ordered the suspension of classes across the entire state network this Thursday (13) due to Civil Defense warnings about the possibility of floods and flash floods.
The formation of an extratropical cyclone near the south of the country should cause winds of up to 120 km/h and heavy rains on Wednesday night (12), with a risk of hail in the three states of the region, according to Climatempo.
The most affected places must be the north coast of Rio Grande do Sul and the mountains of Rio Grande do Sul and Santa Catarina. On Thursday (13), strong winds and rains should reach the coast of São Paulo.

According to the National Civil Defense, the cyclone formed between Paraguay and Argentina, and will arrive in Brazil this afternoon.
“With the advance of the cold front, an intense mass of cold air will reach the country from Wednesday. On Tuesday, maximum temperatures drop in Rio Grande do Sul due to increased cloudiness and rain, but, as of Wednesday, cold air advances over the South and Mato Grosso do Sul”, reported Inmet.
Until this Wednesday afternoon, 11 cities in Rio Grande do Sul had registered the occurrence of hail, according to the state Civil Defense: Derrubadas, Joia, Passa Sete, Vera Cruz, Sobradinho, Arroio do Tigre, Candelária, Ibarama, Porto Lucena, Good view of Cadeado and Encruzilhada do Sul.
The cities of Panambi and Não-Me-Toque registered flooding, while Sede Nova reported a windstorm.
Inmet advises the population of areas affected by the effects of the cyclone to avoid taking shelter under trees and to park their vehicles close to transmission towers and advertising signs.
The body also requests that electrical appliances and the general power supply be turned off and suggests seeking more information from the Civil Defense (phone 199) and the Fire Department (193).
What is an extratropical cyclone?
According to Climatempo, the extratropical cyclone is an area of low atmospheric pressure where the winds revolve around a center, always clockwise, in the case of the Southern Hemisphere, forming a complete circle.
The company reports that, “the lower the air pressure in the center of the cyclone, the stronger the winds and the greater the potential for the development of very extensive clouds, which cause massive and heavy rain, wind, lightning and eventually hail”.
