Overview

• In 24–48 hours, BCR reported extreme totals that far exceeded August norms, including Baradero 156 mm, Chacabuco 146 mm, Pergamino 126 mm and Rosario 102 mm.
• GEA specialists warn the immediate impact is sanitary, with excess moisture raising wheat disease risk and prompting likely increases in fungicide use.
• BCBA says the broad storm improved moisture for winter cereals and sunflower and kept its national harvest projection at 49 million tonnes.
• Producers and rural leaders report delayed planting for maize, sunflower and soy, damaged rural roads and livestock stress, with some districts accumulating 900–1,500 mm since September 2024.
• Short-term forecasts point to a possible new frontal system, while technicians say at least a week without rain is needed to allow drainage and prevent root anaerobiosis.
