On Monday (5/25), the formation of a cyclone is expected to cause new storms throughout the Southern Region. The forecast also indicates the possibility of hail, especially in the western part of the southern states.

Despite the rain, cold weather continues to prevail in areas of the South and Southeast. In the gaucho and catarinense mountains, minimums can reach 4°C. In São Paulo, Minas Gerais, and Rio de Janeiro, the coldest areas are expected to register between 10°C and 12°C.

In the Northeast, the highest volumes are expected to hit the south of Bahia, the coast between Aracaju and Maceió, and the northwest of Maranhão. There is also a forecast of isolated showers in the north of Piauí and Ceará.
