On Wednesday morning, Porto Alegre experienced significant fog that affected airport operations at the Internacional Salgado Filho Airport. One of the flights scheduled to depart for Guarulhos in São Paulo was delayed, taking off nearly an hour late. The weather conditions prompted concerns among travelers and highlighted the impact of atmospheric variations on transportation within the region.

According to Climatempo Meteorology, the state of Rio Grande do Sul is currently under the influence of a cold front impacting the entire southern region of Brazil. This meteorological system contributes to unstable atmospheric conditions, particularly affecting the northern and eastern parts of the state. As a result, much of the area began the day with overcast skies, especially in the metropolitan region of Porto Alegre, surrounded by valleys, the northern coastline, and parts of the central-eastern regions.

Throughout the day, there are predictions for ongoing rain along with the possibility of isolated thunderstorms and occasional strong wind gusts, mainly affecting the northwest, Missions, valleys, metropolitan areas, northern coastline, and parts of northern Rio Grande do Sul. Weather warnings and travel advisories may be necessary to ensure safety for local residents and travelers, as the conditions can impede daily activities and pose hazards to transportation.
