Starting on November 02, areas of instability will intensify and will cause rain showers in Mato Grosso do Sul and central-western São Paulo, which may record accumulations above 11 mm (red and pink tones). In eastern São Paulo and Rio de Janeiro, areas of instability may cause rainfall of up to 80 mm.

Na South, the week begins with stable weather in much of the region, with possible isolated rains in Paraná and eastern Santa Catarina on the 30th and 31st.
