Overview
- Argentina’s national weather service kept orange alerts in effect for Formosa, Corrientes, Salta, Santiago del Estero, Santa Fe, Córdoba, Tucumán, La Rioja and Chaco through December 25.
- Forecasters warn of frequent lightning, occasional hail, 80–150 mm of rain in short bursts and wind gusts that can top 90 km/h in the highest-risk zones.
- Yellow alerts extend to surrounding areas, with the AMBA under a lower-level notice overnight before conditions ease on Thursday, according to the SMN.
- Emergency messaging follows this week’s flash flooding in the AMBA after downpours of 80–100 mm that submerged vehicles and disrupted travel.
- Córdoba intensified holiday enforcement of its citywide pyrotechnics ban with reports to hotline 103, and Mendoza showed forecast divergence as the provincial service flagged isolated storms that national and private outlets did not.
