- The SMN maintains yellow alerts for storms in Misiones, Corrientes, Formosa, Chaco, and parts of Santa Fe, Santiago del Estero and Salta, alongside Patagonian wind advisories of 40–60 km/h with gusts over 90 km/h that could escalate to orange level.
- Mexico’s Tropical Wave 35, interacting with a Gulf surface low and the monsoon, is forecast to deliver intense rainfall in Chiapas and Veracruz and very strong rainfall across Oaxaca, Tabasco, Campeche, Yucatán and Quintana Roo, with flood and landslide risk through late week.
