Storm risk in several northern and northeastern states. Coast of São Paulo and Rio de Janeiro with big waves.
Cloud cover over Brazil
A new cold front advances along the coast of Rio Grande do Sul on Tuesday, prompting an increase in cloudiness and rain over parts of the state. Heavy clouds have already begun to roll over Rio Grande do Sul’s border with Uruguay.
The warm and humid air that prevails in the north and north-east of the country favors the formation of heavily charged clouds, which cause heavy rain showers. On the northern coast of Brazil, areas of instability are reinforced by the action of the Intertropical Convergence Zone. At the same time, the intensification of offshore winds increases the instability on the east coast of the northeast.
The heat and high humidity favor the formation of some thunderstorm clouds also over the Midwest and Southeast of the country.

Southeast region
After the passage of a cold front, associated with a strong extratropical cyclone, the sea remains rough on the coast of the South-East Region of Brazil. Be careful because there is a hangover risk from the Santos region (SP) to São João da Barra (north of RJ).
The sun predominates in the central west and south of Sao Paulo and also on the coast of Sao Paulo. Greater São Paulo and other regions of São Paulo can experience showers and lightning in the afternoon and part of the night. Rain showers and lots of clouds are forecast for most areas of Minas Gerais, including Belo Horizonte. Some knocks can be strong in Noroeste Mineiro.

Many areas of instability continue to form in northeastern Brazil on Tuesday. Practically the whole Region has a day with lots of cloud cover, rain showers at any time and some sunny periods. There is a risk of heavy rains in all states. It could rain moderately to heavily this Tuesday in all capitals in the northeast. There is no rain forecast only for the São Francisco Valley region, in Bahia.
Northern region
The zones of instability continue to grow throughout northern Brazil, with the great availability of heat and humidity that exists in the region.
This Tuesday the weather is dry only in the far north of Roraima, including the Boa Vista region. Elsewhere in northern Brazil there are several rain showers throughout the day, with lightning and sometimes strong winds. But there are also periods with the sun.
