Overview

• Argentina’s national weather service confirmed the system will reach the Buenos Aires metropolitan area over the weekend with intermittent rain and gusts near 50 km/h.
• The Rosario exchange projects 90–130 mm in parts of north and northwest Buenos Aires, while BCBA and INTA warn of locally intense storms with hail and heavy bursts exceeding 100 mm in some areas.
• Rainfall is expected to concentrate over the center‑east of the agricultural area, with lighter totals likely in western zones that still need moisture.
• The Rosario exchange estimates about 1 million hectares are already inundated and another 2 million are affected, raising risks for saturated lowlands as wheat thrives and the nearly finished maize harvest (97.2%) faces new weather interruptions.
• Authorities activated preparedness measures, including municipal advisories and Saturday’s closure of the Paso Cristo Redentor tunnel in Mendoza due to heavy rain and mountain snow.
