Weather forecasts indicate that the heaviest rains are expected to occur this weekend, with a continuation scheduled for Monday.
The last days of 2024 and the beginning of 2025 will not be marked by intense rain, the result of the action of a South Atlantic Convergence Zone (ZCAS). This meteorological phenomenon, which acts as a moisture channel, can cause landslides, especially in the Mountain Region, including areas such as Petrópolis. The volume of precipitation can reach up to 400 millimeters in several locations over the course of a week. The ZCAS will affect not only Rio de Janeiro, but also the Central-West and Southeast of Brazil, with Minas Gerais being one of the most impacted states. Weather forecasts indicate that the most intense rains are expected to occur this weekend, with a continuation expected on Monday. From Tuesday onwards, the ZCAS should move towards Espírito Santo, which could result in a decrease in the intensity of rain in Rio.
Although ZCAS is known for its duration, there is no indication that it will be particularly intense. The National Natural Disaster Monitoring and Alert Center (Cemaden) is monitoring the situation closely. It is important to highlight that the ZCAS is not related to the La Niña phenomenon, which could occur in 2025, but in a less intense form. Petrópolis Civil Defense issued a warning about the forecast of moderate to heavy rain until next Monday. The population is advised to avoid areas prone to flooding and to remain alert for possible signs of landslides.
