Overview
- The National Weather Service expanded yellow and orange alerts Tuesday to Mendoza, Neuquén, Río Negro and Chubut, citing 50–70 km/h winds with local gusts above 100 km/h and 20–60 mm of rain.
- In the Buenos Aires metro, forecasters see a 40–70% chance of thunderstorms late Wednesday, then cooler air and stronger southwest winds into Friday and Saturday.
- The gusty spell ties to an extratropical cyclone over the Argentine Sea, a deep low‑pressure system over cold water that speeds up onshore winds as it intensifies.
- Galicia’s Pontevedra towns faced a cloudy Monday with afternoon showers, a high chance of thunder, and peak gusts near 32–36 km/h, according to Spain’s AEMET.
- Parts of Mexico pivot from light rain to dangerous heat this week, with Mexicali near 39°C and very high UV and Valladolid projected at 40–41°C, while Poza Rica holds light showers.
