Intense rain is expected in the Southeast region of Brazil this weekend, with the possibility of storms affecting the post-carnival 'bloquinhos' and champion parades in cities like São Paulo and Rio de Janeiro. Meteorological forecasts indicate that the heavy rains could start from Saturday afternoon, raising concerns about flooding as rainfall accumulations may exceed 100 mm in certain areas.

The National Institute of Meteorology (Inmet) has issued multiple alerts for rainfall severity, categorizing risks from 'potential danger' to 'great danger' across various regions, including the Southeast, South, Central-West, North, and Northeast of Brazil. The most alarming warnings suggest that some areas could see rainfall rates greater than 60 mm per hour, particularly in the Southeastern states.

The impact of these weather conditions could disrupt planned carnival festivities, which attract large crowds in urban centers. Local authorities are likely to prepare for emergency responses to potential flooding, especially in vulnerable areas, highlighting the need for public safety measures during this weather event and for future extreme weather events in Brazil.
