Municipalities within the Arroyo San Francisco-Las Piedras basin in Buenos Aires Province initially met to coordinate flood mitigation and infrastructure maintenance in response to forecasted storms. This coordination involved technical teams from several municipalities, including Avellaneda, Florencio Varela, Lanús, and Almirante Brown, alongside provincial ministries and water authorities.

Governor Axel Kicillof has since expanded the scope of response by launching a provincial prevention and mitigation plan exceeding 2.3 trillion pesos to address the ‘Super Niño’ climate phenomenon. This strategy involves an interministerial table to coordinate actions across the province’s 135 municipalities and is organized into three levels: monitoring and information, prevention, and structural works. Key measures include expanding the meteorological station network, implementing a provincial monitoring visor, and conducting hydraulic maintenance such as dredging and cleaning streams.

Authorities have warned of a 90% to 95% probability of intense weather events occurring toward the end of spring and the beginning of summer. Kicillof has criticized the national government under President Javier Milei, alleging that the administration is withholding 293 billion pesos from the Water Fund and 2.1 trillion pesos in National Treasury Contributions (ATN), which he argues hinders the province’s ability to manage climate risks. Additionally, agricultural organizations such as CARBAP have expressed concern that rural infrastructure and roads remain inadequate to handle expected heavy rainfall and saturated soils.
