Brazil’s National Institute of Meteorology (INMET) issued an orange storm warning on Monday (Jan. 12) for the coastal areas of the states of São Paulo, in the Southeast, and Paraná and Santa Catarina, in the South.

The increased rainfall is still an effect of the passage of an extratropical cyclone, which caused damage in cities in both the South and the Southeast over the weekend.

The cyclone has begun to move away from the continent toward the ocean, but the alert remains in place for heavy rainfall, which could reach up to 100 millimeters (mm) per day, and intense winds with gusts of 60 to 100 kilometers per hour (km/h).

The extratropical cyclone formed last Friday (9), affecting the Southern states of Paraná, Santa Catarina, and Rio Grande do Sul.

In Rio Grande do Sul, 18 cities were affected by increased precipitation and strong winds that caused trees to fall, areas to be flooded, and roofs to be blown off houses. In Santa Catarina, the Civil Defense reported that, by Monday, 15 municipalities had registered damage affecting 91 houses and five public structures.

Last Saturday (10), the municipality of São José dos Pinhais, in Paraná, recorded a tornado with winds reaching 180 km/h. The phenomenon was classified by the authorities as category F2 on the Fujita scale, which goes up to five.

The tornado is said to have affected 1,200 people and damaged 350 homes. Two people were slightly injured.
