Overview
- Argentina’s national service (SMN) issued orange alerts for Sunday covering parts of Buenos Aires, Santa Fe, Córdoba, San Luis, La Pampa, Entre Ríos, Corrientes, Formosa, Chaco and Misiones, warning of hail, intense lightning, 40–80 mm of rain and gusts that can exceed 90 km/h.
- Additional SMN yellow advisories extend to surrounding provinces for thunderstorms and strong winds, with southern-sector gusts forecast over Buenos Aires and neighboring areas through the afternoon and evening.
- In the Buenos Aires metro area, officials flagged late‑Saturday storms and a Sunday pattern of morning downpours followed by strong southerly winds and cooler highs near the low 20s Celsius.
- In Spain, ‘borrasca Claudia’ and an advancing front are producing unstable weather, with earlier Meteocat orange and yellow notices in Pyrenean and Pre‑Pyrenean comarcas and AEMET‑based town forecasts in Galicia calling for high storm probabilities and gusts reaching roughly 50–60 km/h on Sunday after stronger bursts on Saturday.
- Authorities in both countries advise securing loose items, avoiding flooded routes and monitoring local updates, with Catalonia also expecting rain to wash Saharan dust out of the air and dirty surfaces.
