The National Institute of Meteorology (INMET) has issued a weather warning for the state of Piauí, Brazil, concerning the expected heavy rains from Saturday (7) through Monday (9). The forecast anticipates rainfall rates of 20 to 30 mm per hour, with the possibility of accumulating up to 50 mm per day. Additionally, strong winds ranging from 40 to 60 km/h are also expected during this period. The warning highlights the increased risk of flooding and landslides due to saturated areas from previous rains, emphasizing the potential danger to residents and infrastructure.

The adverse weather conditions are attributed to several meteorological phenomena, including the Intertropical Convergence Zone (ITCZ), a high-altitude cyclonic vortex (VCAN), and local convective systems. These factors contribute to the escalation of cloud formation and significantly increase the likelihood of intense rain showers. The authorities are concerned that some locations may experience rainfall exceeding 60 mm, further exacerbating the flooding risks in already waterlogged areas.

In light of the anticipated severe weather, INMET has issued safety recommendations for residents to follow during windy conditions. These include avoiding sheltering under trees due to the risk of falling branches and lightning, not parking near transmission towers or billboards, and refraining from using electronic devices during thunderstorms. The authorities are taking proactive steps to ensure public safety and preparedness as the adverse weather approaches the region.
