Overview

• The SMN’s Oct–Dec outlook calls for temperatures normal to above normal across most regions, reflecting ENSO‑neutral conditions with the northwest near seasonal norms.
• Seasonal precipitation signals suggest wetter conditions in the far north and potential hydric deficits in the west of the Pampas, Cuyo and northern Patagonia.
• Active yellow and orange alerts cover Río Negro, Chubut, Santa Cruz and Tierra del Fuego for strong westerly winds of 40–60 km/h with gusts near 90 km/h, rising to 60–70 km/h with gusts that may exceed 120 km/h in orange zones.
• Patagonian and Andean cordillera sectors of Neuquén, Río Negro, Chubut and Santa Cruz remain under snow alerts with expected accumulations of roughly 20–30 cm and locally higher totals.
• Short-term forecasts show improving conditions in AMBA and several central provinces with cool mornings and highs near 22–23°C, and officials urge securing loose objects, limiting outdoor exposure and keeping emergency kits ready.
