The Carnival period in Piauí, Brazil, is expected to experience heavy rain from February 14 to 17 according to the State Department of the Environment and Water Resources (Semarh). Major cities such as Parnaíba, Água Branca, Teresina, and Floriano are predicted to be most affected by intense rainfall and winds. Teresina's weather will fluctuate between cloudy, sunny, and rainy during the day, while nights will bring heavier downpours, leading to potential storms.

In addition to Teresina, the regions of Bom Jesus, Corrente, Picos, Barras, and Piracuruca are also under storm warning during this festive period. The National Institute of Meteorology has issued guidelines for residents, advising them to avoid seeking shelter under trees due to the risk of falling limbs and lightning strikes. Furthermore, people are warned against parking vehicles near transmission towers and advertising billboards to mitigate risks associated with severe weather conditions.

The anticipated heavy rainfall could disrupt Carnival celebrations, which typically attract large crowds. Organizers and attendees alike may need to prepare for changing conditions, including the likelihood of event cancellations or modifications in scheduling due to safety concerns related to the weather. Overall, the weather conditions underline the importance of safety precautions during public events, especially in regions prone to sudden storms.
