The National Institute of Meteorology (Inmet) of Brazil has announced two red alerts of great danger due to impending heavy rainfall expected to impact areas across the Southeast and South regions of the country on Thursday (12). These warnings commence at midnight and remain effective until 11:59 PM on the same day. The forecast indicates potential rainfall exceeding 60 millimeters per hour or more than 100 millimeters over a single day, which are considered extremely high levels likely to cause considerable disruption in the affected areas.

The red alert is the highest level of warning issued by Inmet, highlighting the severity of this weather event. The warnings encompass extensive regions including São Paulo, Minas Gerais, and Rio de Janeiro, where municipalities such as Campinas, Piracicaba, and the Macro Metropolitan region of São Paulo are under threat. Additional areas at risk include the Vale do Paraíba Paulista, southwestern and southern regions of Minas, the Zona da Mata, Campo das Vertentes, as well as various zones within Fluminense that are anticipated to face heavy rainfall.

This forecast poses a significant challenge for local authorities and emergency services, as the potential for flooding and landslides increases with such high precipitation levels. Residents in the affected areas are advised to take precautions to minimize risks associated with severe weather, given the high likelihood of serious disruptions to daily life and infrastructure from the intense rainfall expected on Thursday.
