Overview
- The national meteorological service issued yellow alerts for extreme cold across several northern and central provinces as a strong southern air mass drives a sharp temperature drop between Tuesday and Thursday.
- High Andean and mountain zones reported severe conditions with heavy snow, icy roads and driver-shared readings near -23°C plus gusts over 80 km/h that reduced visibility and disrupted transport in San Juan.
- Snow dusted the hills around Salta while the Buenos Aires metro area faces single-digit lows and a 10–40% chance of nighttime showers with daytime highs near 12°C, and heavy rain is likely along parts of the Atlantic coast.
- Agricultural monitors warn that several consecutive cold days and expanding frost risk could damage frost-sensitive crops and raise costs for livestock care, prompting producers to prepare protective measures.
- Climate context from IRI shows a moderate El Niño consolidated in May–June that raises odds of above-average seasonal temperatures for some provinces but leaves precipitation signals weak and does not prevent short-lived polar outbreaks.
