- Yellow wind alerts cover western Neuquén with sustained 40–65 km/h and gusts above 100 km/h, while southern Mendoza is under a Zonda warning for hot, dry downslope winds that can reduce visibility and rapidly raise temperatures.
- Greater Buenos Aires faces an unstable spell with rain chances from Monday midday, a higher risk of strong to severe storms on Tuesday with powerful gusts as a front moves through, and a noticeable cooldown with improving conditions on Wednesday.
- La Plata set a local Yellow risk level for Tuesday and activated monitoring and prevention operations, advising residents to secure loose objects, avoid flooded areas, and use caution when driving during possible strong storms.
- Mendoza’s contingency office flagged Zonda in Malargüe and early‑morning storms in the south with a temperature drop, while Salta expects heat to spike Tuesday before evening storms under an SMN alert and a cooler, wetter turn from mid‑week; by contrast, Galicia (Spain) stays dry and Mexican localities report hot, rain‑free days.
