The National Institute of Meteorology (Inmet) in Brazil has issued a yellow alert for intense rains affecting the entire state of Maranhão, warning residents of potential hazards. The alert, valid until the end of Tuesday, October 10, indicates a likelihood of rainfall between 20 and 30 millimeters per hour, which could accumulate to 50 millimeters in a single day. Additionally, strong winds reaching speeds of 40 to 60 kilometers per hour are expected, increasing the risk of power outages, fallen branches, flooding, and lightning strikes.

Residents are advised to exercise caution, particularly those who plan to go outside, as the weather could pose significant dangers. The alert highlights the need for heightened awareness in the region, particularly in the four municipalities that comprise the Greater São Luís area, which could see the most direct impact from the meteorological conditions. On Monday, while São Luís experienced sunny weather and temperatures between 24°C and 28°C, the situation may change dramatically as evening approaches, with reduced humidity likely.

The issuance of this alert underscores the volatile nature of weather patterns in Brazil, particularly during this time of the year when seasonal rains can swiftly escalate into severe weather events. Local authorities and residents alike are urged to remain vigilant and prepare for possible emergencies as the forecast develops over the coming days.
