Overview

• On July 15 the national weather service issued yellow alerts for storms and gusty winds across eight provinces including Buenos Aires, Córdoba and La Pampa ahead of a deepening low-pressure system.
• Orange warnings expanded into the AMBA and central Argentina predicting up to 100 mm of rain, hail showers and wind gusts reaching 50–60 km/h at the system’s peak on July 16.
• By early July 16 scattered showers gave way to a cold front that generated dense fog across the Pampas, reducing visibility and grounding several domestic and regional flights.
• The Dirección de Contingencias Climáticas reported Andean snowfall and lows near 5 °C, leading to high-altitude pass closures and traffic disruptions in mountain areas.
• Authorities have urged residents to secure loose objects, avoid outdoor activities, prepare emergency kits and monitor official bulletins as variable winter conditions persist.
