Overview

• Argentina’s meteorological service issued yellow and orange alerts across central and eastern provinces, with conditions worsening from Saturday night and the most intense phase expected on Sunday.
• Forecasts call for widespread totals of 20–120 mm with local peaks near 120–150 mm, with storms capable of producing electrical activity, hail, and damaging wind gusts, including up to 90 km/h in southern Santa Fe.
• Mendoza moved to a provincewide orange alert for persistent rainfall of 50–90 mm with the chance of mountain snow, as Defensa Civil warned of potentially exceptional accumulations in Gran Mendoza and urged preparedness.
• Córdoba and the Rosario area expect storms from early Saturday through Sunday; municipal and provincial agencies intensified drain cleaning, activated emergency committees, and issued guidance to avoid travel during heavy downpours.
• Agronomic monitors cautioned that the core farming belt—especially north and northwest Buenos Aires—could receive 90–130 mm, exacerbating existing inundations and threatening wheat conditions and early corn planting.
