A severe weather warning has been issued by Brazil's National Institute of Meteorology (Inmet) for the Piracicaba region, indicating intense rainfall that could accumulate to between 50 and 100 millimeters per day until Friday evening (27th). Following this, drier weather is anticipated starting Saturday (28th), with temperatures dipping to around 13°C, particularly in Piracicaba and Limeira. The cold mornings are expected to last until Monday (2nd), indicating a significant weather shift after the recent storms.

The intense rainfall, with reports of up to 100 millimeters falling in just two hours in places like Capivari, has caused significant flooding and overflowing of streams. This severe weather pattern is being attributed to the fifth episode of the South Atlantic Convergence Zone (ZCAS), which is actively influencing the Brazilian weather from Thursday to Sunday (1st). The rains have raised concerns over local infrastructure and safety, as citizens face challenges from the resulting flooding.

In light of the heavy downpour and the subsequent cold weather forecast, residents are advised to prepare for the chilly conditions while also coping with the repercussions of the storms. The weather changes are a reminder of the growing impact of climate patterns like ZCAS and highlight the importance of weather preparedness in affected regions. Moreover, this situation serves to underline the broader implications of climate phenomena in Brazil, emphasizing the need for continued monitoring and community preparedness in the face of extreme weather events.
