2/4/2026, 10:22:31 PM
Current Weather Conditions and Alerts
São Paulo is currently experiencing significant weather disruptions due to a low-pressure system forming off the Sudeste coast. The city has implemented a vehicle restriction known as "Rodízio," affecting plates ending in 5 and 6 during peak hours from 7 AM to 10 AM and 5 PM to 8 PM in the Centro Expandido area. Violations of this rule incur a fine of R$130.16 and four points on the driver's license. The city is under a yellow alert from the National Institute of Meteorology (INMET) for intense rain, with forecasts predicting heavy rainfall and potential localized flooding through Saturday, February 7.
In Rio de Janeiro, the city entered Estágio 2 on February 3 due to heavy rainfall, particularly impacting the Zona Oeste, where Campo Grande recorded 42.4 mm of rain. The INMET has issued an orange alert for storms, warning of rainfall rates between 30 to 60 mm per hour and wind gusts up to 100 km/h. The combination of saturated soil from previous rains and ongoing precipitation raises the risk of landslides, especially in the Região Serrana.
Practical Guidance for Residents
Residents in both cities are advised to avoid areas prone to flooding and to refrain from crossing inundated roads. In São Paulo, it is recommended to check traffic updates before commuting and to stay away from trees and metal structures during storms. In Rio de Janeiro, the public is encouraged to stay hydrated and avoid prolonged sun exposure, despite the rain, as the heat index is expected to remain high.
Criticism and Opposition
While the authorities have issued alerts and guidelines, some residents express frustration over the lack of timely communication regarding the severity of the weather conditions. Critics argue that more proactive measures could be taken to mitigate the impacts of flooding and landslides, particularly in vulnerable areas.
Official Statements & Responses
The São Paulo Civil Defense has emphasized the importance of adhering to safety protocols during severe weather, stating, "We are monitoring the situation closely and urge residents to remain vigilant." Similarly, the Rio de Janeiro authorities have advised citizens to register for SMS alerts from the Defesa Civil to stay informed about weather updates and emergency procedures.
