Ciclone and cold front forecast to bring storms across Brazil
A moderate to strong cyclone is forecast near Santa Catarina on November 4 or 5.
It is expected to form as a low-pressure system strengthens between Paraguay, Argentina and southern Brazil.
The cyclone will create a cold front, which is forecast to spread storm risks across several regions.
Storms may begin as early as November 2 in Santa Catarina, Paraná, Mato Grosso do Sul and São Paulo, then extend to other states through November 7.
The front could bring heavy rain to parts of the Southeast and Center-West, and later to areas including Bahia, Maranhão and Piauí.
Polar air is expected to lower temperatures in southern Brazil from November 5 and reach parts of the Southeast on November 6.
By November 7, temperatures are expected to be milder and the chance of rain lower in the areas affected by the cold air.
An extratropical cyclone is forecast to form near the coast of Santa Catarina between November 4 and 5.
The system is expected to be moderate to strong and to generate a cold front that could bring storms across parts of Brazil.
Storm risks are forecast to spread from southern states early in the week toward the Southeast, Center-West and parts of the North and Northeast.
Polar air is expected to lower temperatures in the South and parts of the Southeast.
