Overview

• Argentina’s SMN seasonal outlook for October–December favors above‑normal temperatures across most regions, led by Córdoba with about a 55% probability, while the NOA is projected near normal.
• Precipitation outlooks point to wetter chances in the northern provinces and potential deficits in the west of the Pampas, Cuyo and northern Patagonia.
• SMN maintains yellow and orange alerts in Patagonia for strong westerly winds of 40–60 km/h with gusts up to 90 km/h, locally 60–70 km/h with gusts above 120 km/h, plus 15–30 mm of rain and 20–30 cm of snow in Andean areas.
• Short‑term forecasts in Argentina show improvement after Saturday’s rains in the AMBA and a warming trend early this week, with highs around 30–32 °C in several provinces including parts of the northwest and center.
• In Mexico, SMN/Conagua expect very strong to intense rains from Monday to Wednesday in multiple states with flood and landslide risks, chubascos and 2–3 m waves in Baja California tied to distant Hurricane Narda, and rising northwest heat with Hermosillo near 37–41 °C and heat indices reported up to 45 °C.
