São Luís is expected to experience unstable weather this Sunday, with forecasts of showers and isolated thunderstorms as per the Instituto Nacional de Meteorologia (Inmet). The temperatures will range from 24°C to 28°C, contributing to a humid atmosphere. Relative humidity might reach up to 100% in critical periods, while the minimum humidity expected is at 75%. The weather pattern indicates intermittent rain in the morning, afternoon, and throughout the night, accompanied by isolated thunderstorms, with weak winds from the southeast to northeast without strong gusts.

The Inmet has issued a warning for heavy rainfall starting at 9:58 AM on Saturday, the day before, applicable to several municipalities in Maranhão. As São Luís is a coastal capital, the implications of heavy rainfall could lead to urban flooding and disruptions in local transportation. This alert serves as a precaution for residents, encouraging them to stay updated about the weather conditions.

The high humidity levels and the expected precipitation could also pose concerns regarding health, particularly respiratory issues, as the stagnant water can become breeding grounds for mosquitoes. Therefore, citizens are urged to remain cautious and prepared for potential changes in the weather that could affect their weekend plans.
