An extratropical cyclone is expected to form this Friday on the northern coast of Rio Grande do Sul, bringing severe storms to the South and Southeast regions of Brazil. The National Institute of Meteorology (Inmet) warns of tornado risk, mainly in the state of Paraná, where conditions are expected to be most critical.
According to Inmet, the most affected areas should register rain exceeding 60 millimeters per hour, winds above 100 km/h, and hail. The entire state of Paraná, from Curitiba to the border, is under red alert, which denotes "great danger" due to the forecast of damage to buildings, power outages, destruction of crops, falling trees, flooding, and transportation disruptions.
The cyclone, which is expected to form this Friday and continue acting tomorrow, will move toward the ocean, intensifying the bad weather that has already settled in the South region. The most complicated day will be this Friday, when the highest levels of instability and risk of severe weather are concentrated.
