AI-generated summary
The passage of a wind system and depression in the atmosphere changes weather conditions in the region during the election weekend.
The weekend of the first round of the 2026 elections will be marked by changes in the weather in Vale do Paraíba and the region. The passage of winds in the atmosphere should favor the occurrence of rain on Saturday (3). On the other hand, temperatures are expected to rise on Sunday (4), voting day.
According to meteorologist Gustavo Escobar, from the National Institute for Space Research (Inpe), the system advances slowly and should influence weather conditions, especially on Saturday.
"This trough is advancing very slowly. The tendency is for it to act during Saturday and then move away. It is causing these rains and bringing this humidity", he explains.
On Sunday, the forecast is for longer periods of sunshine, with temperatures rising throughout the day. The heat, however, may favor the formation of rain showers in the afternoon.
"Sunday will be a day with greater sunshine. The sun appears, the temperature rises and, in the afternoon, the daytime heating should cause some localized showers", says Escobar.
Monday (5) should follow a similar scenario: the day starts with periods of sun, but there is a possibility of rain showers throughout the afternoon.
Alert
Due to the possibility of heavy rain, Civil Defense issued an alert for the state of São Paulo. In some places, the rain can be intense and accompanied by lightning and gusts of wind.
