On Friday, September 13, 2023, intense rainfall was reported across multiple regions of Mato Grosso do Sul, Brazil. The heavy rains are associated with the collision of moist air from the Amazon rainforest and an advancing cold front from the south of the country. The southern regions of the state are facing the highest risk of severe storms, including moderate to heavy rain, lightning, and wind gusts potentially reaching 70 km/h.

Forecasts indicate that areas towards the south will experience markedly poor weather throughout the day, with flash floods expected due to the accumulation of rain. Other regions in the state such as the west, southwest, center, north, southeast, and east — including the capital — are also anticipating showers that may be strong in isolated parts, accompanied by lightning and winds up to 60 km/h. Residents are advised to take precautions due to the severe weather conditions.

Among the hardest-hit areas, the northern parts of Mato Grosso do Sul are predicted to receive the most significant rainfall, with projections showing up to 27 millimeters in Figueirão and 17 millimeters in Alcinópolis. Meanwhile, Costa Rica and Chapadão do Sul are expected to have moderate rainfall ranging from 11 to 13 millimeters, coinciding with temperatures ranging from 21 °C to 29 °C. This situation prompts a careful watch over both the immediate effects of the storms and the long-term implications for the region's climate and agriculture.
