As autumn begins today in Brazil, meteorologists are warning of possible flooding and unpredictable weather patterns in the state of Rio Grande do Sul. The forecast suggests that rainfall will be slightly above average this season, resulting in a mix of warmer days and colder spells. Marcelo Schneider, a meteorologist at the National Institute of Meteorology (Inmet), highlights the expected transition period in the early days of autumn, characterized by the arrival of cold fronts leading to potential rain today.

The weather forecast indicates that while early autumn may bring rain as a cold front moves in, conditions are expected to improve by the following week. However, the overall projection for the month of April suggests persisting irregularities in temperature and precipitation. Schneider emphasizes that this autumn's weather will consist of alternating heat and cold air masses, particularly in the latter half of the season, when influences from the El Niño phenomenon are anticipated to become notable, potentially resulting in more favorable rainfall patterns for the region.

While the arrival of El Niño is expected to provide some stability in the weather patterns, meteorologists caution against direct comparisons with previous years due to the uncertainty surrounding such climatic phenomena. Overall, residents of Rio Grande do Sul should prepare for a mix of weather conditions, which could impact agriculture and daily life throughout the season.
