The Mato Grosso do Sul Environmental Institute (Imasul) has reported fluctuating river levels across the state. Initially, monitoring showed varying conditions: the Dourados river rose to 423 centimeters, exceeding its alert threshold, while the Miranda river remained above its alert threshold despite a slight decrease. Other rivers, such as the Taquari and Paraguai, also showed signs of declining levels.

Subsequent reports indicate a shift toward extreme weather, with temperatures in regions like Três Lagoas reaching between 37°C and 40°C and low humidity levels reported. During this period, river levels continued to fluctuate; the Rio Dourados saw a significant decrease of 82 centimeters, while the Rio Piquiri/Cuiabá and parts of the Rio Paraguai recorded slight elevations.
