Overview

• Argentina’s meteorological service issued yellow alerts for Buenos Aires and multiple provinces this weekend for storms with heavy rain, electrical activity, strong winds and possible hail tied to a deep cyclogenesis.
• The Rosario Board of Trade projects very large, uneven rainfall with 90–130 mm possible in the north and northwest of Buenos Aires, with models also signaling a shorter follow‑up event early next week.
• Roughly 1 million hectares are already waterlogged in the core farm belt and another 2 million are affected, raising risk to winter wheat and early maize planting despite generally strong crop condition ratings.
• Mexico City activated orange and yellow rain alerts across several boroughs, reported street flooding at sites including Barranca del Muerto and Jardines del Pedregal, and continued preventive drain cleaning under Operativo Tlaloque.
• Local authorities in Santa Fe and Córdoba advanced drainage and pump maintenance, while Mendoza announced a Saturday closure of the Paso Cristo Redentor due to heavy precipitation and high‑elevation snowfall forecasts.
