São Paulo is under a red alert for heavy rains on Wednesday, particularly affecting a large area that includes the regions of Campinas, Ribeirão Preto, and São José do Rio Preto. According to the National Institute of Meteorology (Inmet), these areas may see rainfall accumulations reaching up to 100 mm within a 24-hour period. This extreme weather poses significant risks of flooding and river overflow, as well as landslides due to saturated soils.

The metropolitan region of São Paulo and the entire coastline are under an orange alert, which indicates danger but with a slightly lower risk level compared to the red zone. In these areas, the forecasted rainfall is also anticipated to hit 100 mm, yet the chances of landslides are reduced. However, residents in the orange alert areas should prepare for power outages, fallen trees, and localized flooding, as wind gusts are expected to range from 60 to 100 km/h.

The instability in the Southeast region this week can be attributed to atmospheric conditions that have resulted in severe weather alerts. Authorities urge residents to take precautions, especially in high-risk regions, to mitigate the impacts of potential flooding and other weather-related issues. The upcoming rainfall could greatly disrupt daily life and infrastructure within the affected areas, necessitating awareness and preparedness against natural hazards.
