The National Institute of Meteorology (Inmet) has issued a yellow warning for potential storms. The alert covers the region stretching from central-south São Paulo, through Paraná and Santa Catarina, to the far north of Rio Grande do Sul.

This advisory indicates that atmospheric conditions could generate intense rainfall, thunder, and strong winds in the mentioned areas. The purpose of the yellow alert is to inform the population and local authorities about the need for increased caution and the adoption of preventive measures.

What Does a Yellow Alert Mean?

The yellow alert is the first of three alert levels issued by Inmet, signaling potential risk, but without the severity of red or orange levels. When issued, it is recommended that the public follow meteorological updates and avoid risky situations, such as remaining in areas vulnerable to flooding.
