Temperatures should see a slight reduction in some capitals; in São Paulo, the maximum for this Wednesday will be just 26°C
Brazil begins the month of December with a significant increase in the risk of storms in several regions, especially the Southeast and Center-West of the country. The La Niña phenomenon, characterized by the cooling of the waters of the Pacific Ocean, is mainly responsible for the intensification of rain. This climate event generates more “humidity corridors” over Brazil, resulting in more rain.
A storm risk map indicates a heavy rain warning in several states. Regions most at risk include:
- Southeast: Zona da Mata Mineira, East of Minas Gerais, interior of Rio de Janeiro, the capital of São Paulo, the metropolitan region of São Paulo and areas of Espírito Santo.
- Midwest and North: Mato Grosso, Mato Grosso do Sul, Goiás, Rondônia and Acre.
The forecast points to the possibility of up to 100 millimeters of rain, with a warning issued by Civil Defense for areas at risk.
Rain situation by region
The rain map for this Wednesday (3) reinforces the instability projection:
- Southeast: There is instability in Rio de Janeiro and Vitória (ES), with the possibility of rain.
- On the: Santa Catarina and Paraná face instability with the potential for heavy rain. Rio Grande do Sul, under the influence of La Niña, will have firmer weather and more spaced-out rains.
Falling temperatures in the Southeast
Temperatures should see a slight reduction in some capitals. In São Paulo, which recorded 30ºC on Tuesday (2), the maximum for this Wednesday will be just 26°C. This drop is associated with the arrival of a cold front, which causes rain and a decrease in temperature. The maximum temperatures in other capitals such as Cuiabá (29°C), Campo Grande (30°C) e Porto Alegre (28°C) remain high.
