The National Institute of Meteorology (Inmet) has warned residents of Maranhão, Brazil, about imminent heavy rainfall by issuing a yellow alert for 215 municipalities. The alert is active until 10 a.m. on Monday, indicating that citizens in these areas should prepare for potential severe weather impacts. Only two cities, Porto Rico do Maranhão and Raposa, are excluded from this alert, underscoring the broader scope of the affected areas in the state.

Meteorologists predict that rainfall could reach between 20 to 30 millimeters per hour, possibly accumulating up to 50 millimeters throughout the day. This intense precipitation could also be accompanied by strong winds, speeds ranging from 40 to 60 km/h, posing additional risks to residents. Inmet advises that while the risk of significant incidents like power outages and tree falls is low, the possibility of flooding, landslides, and lightning strikes remains a concern.

To ensure the safety of the public, Inmet has issued safety guidelines including avoiding shelter under trees during strong gusts and parking vehicles away from transmission towers and advertising signs. Residents are also urged to disconnect electrical appliances, especially during severe weather to mitigate risks of damage or hazards. With the rainy season often bringing disruptions, this alert highlights the importance of public awareness and preparedness in facing extreme weather events in the region.
