The area hit by the main storm was the central and southern Argentine Litoral region, comprising the south-center of Santa Fe Province (west of the Paraná River) and the south of Entre Ríos Province (east of the Paraná River). The latter is part of the southern Mesopotamia (lit. "between rivers", thus called because it lies within the drainage basin of the Paraná and the Uruguay River). Increased rainfall also hit locations in the northeast of Buenos Aires Province, along the course of the Paraná, before it empties into the Río de la Plata (beside which Buenos Aires is located). Associated storms hit the southeast of Córdoba Province, immediately west of Santa Fe.
