Overview
- A frontal system that produced rain, thunderstorms and gusts up to about 50 km/h on September 2–3 has passed Buenos Aires, leaving clearer skies and daytime highs in the mid‑teens with single‑digit night lows as of Friday.
- National forecasts and model analyses say the cold spell will persist through the weekend and may bring variable precipitation across Argentina, including mountain snow in the Andes.
- Forecasts identify an elevated risk of strong winds and localized severe phenomena, including possible tornadoes in the central 'zona núcleo' and sustained gusts reported between roughly 42 and 59 km/h in some provinces.
- The provincial Sistema de Alerta Temprana placed northwest Tucumán — including Tafí del Valle — under a yellow wind alert that warns of sustained winds to 70 km/h and gusts up to 100 km/h in high terrain.
- Regional contrasts are sharp: AEMET predicts warm, sunny weather with highs near 30–34°C across parts of Galicia, Spain, underscoring that the cold front affects Argentina but not broader Atlantic Europe; residents should follow short‑range local updates for transport and vulnerability risks.
