Brazil is bracing for varied weather conditions on February 19, 2025, with forecasts indicating instability across several regions including the Amazon, São Paulo, and Minas Gerais. A significant weather pattern, known as the Vórtice Ciclônico em Altos Níveis (VCAN), is expected to impact the weather significantly, particularly over states like Mato Grosso and Rondônia.
Starting with the Amazon region, the weather forecast for Wednesday predicts reduced moisture outflow, though the presence of significant cyclonic activity from the VCAN will keep weather disturbances high. According to the Diário da Amazônia, areas like Rondônia will see cloudy skies with possible thunderstorms and rain, particularly during afternoon hours. Porto Velho will experience temperatures ranging from 23°C to 30°C and may face sudden heavy rain, urging residents to stay alert to changing weather conditions.
Moving south to São Paulo's Guarulhos, the temperature is forecasted to stabilize at around 18°C with clear night skies, but the day is not expected to remain dry. There is a probability of scattered showers developing throughout the day, with highs reaching 31°C and lows around 20°C. Rain predictions stand at 100% probability, posing challenges for daily activities as residents may need to seek shelter from expected rain, which could accumulate significantly.
Similarly, Paraná will witness atmospheric instability with thunderstorms likely across the region. The weather throughout Paraná is expected to remain warm, with maximum temperatures close to 30°C. The region is set for stormy conditions, making it unpredictable and requiring precautionary actions as strong thunderstorms are possible at any moment.
Meanwhile, Maringá, located within Paraná, is set for another day of summer-like weather characterized by moisture and expected rain. The temperature will begin at 22°C and peak at 29°C, indicating pleasant moments but complicated by high humidity levels of 62% to 97%. The sky will carry nearly 96% chances of rain and 11.1 mm of expected precipitation throughout the day. Residents are advised to prepare by having rain gear on hand, as intense bursts of rain and gusts of wind reaching up to 49 km/h may occur.
On the eastern coast, Vila Velha, ES, shows slightly moderate conditions kicking off the day at 21°C with high moisture levels indicating humidity of 88%. Forecasts predict sporadic rains with maximum temperatures around 29°C.

Finally, Belo Horizonte's weather on February 19 reflects typical summer conditions, with rising temperatures and high humidity. Expected temperatures will average between 20°C to 30°C. The forecast lends itself to rain throughout the afternoon and evening, with swift thunderstorms potentially disrupting local transport. To mitigate related inconveniences, locals should plan outdoor activities during the morning when conditions are more stable and cool.
Advice for residents throughout these affected areas should focus on hydration due to high temperatures, traffic safety during adverse weather conditions, and readiness to adapt plans according to the real-time weather updates. Staying informed through local meteorological agencies is advised to cope with the volatile weather.
