The National Meteorology Institute (Inmet) has issued severe weather warnings for Rio Grande do Sul, particularly highlighting Porto Alegre, which experienced intense rainfall around noon. The warnings include a yellow alert indicating potential danger due to expected rainfall accumulation of up to 50 mm per day, along with winds ranging from 40 to 60 km/h and the possibility of hail. These conditions are expected to persist, creating a risk for the population and infrastructure.

A more severe orange alert has also been issued, extending into Wednesday morning, warning of even heavier rainfall between 30 to 60 mm per hour or 50 to 100 mm per day, which could be accompanied by winds reaching 100 km/h, the likelihood of hail, and potential interruptions in electricity supply. The severe weather could also cause damage to crops and lead to fallen trees, raising concerns for both agriculture and urban areas in the state.

The weather forecast indicates an unstable atmosphere across a significant portion of Rio Grande do Sul, attributed to the advancement of instability in the region and the approach of a cold front from the south. These atmospheric conditions are conducive to isolated storms, suggesting that residents should remain vigilant and heed the warnings issued by meteorological authorities to minimize risks during this stormy period.
