Overview
- The Servicio Meteorológico Nacional issued yellow alerts for Thursday covering convective storms in Salta, Formosa and Misiones, heavy rain in cordilleran areas of Neuquén, Río Negro and Chubut, and Zonda winds in southern Mendoza.
- Northern storm warnings forecast short, intense downpours of 30–50 mm in places, frequent lightning, hail and wind gusts that can reach about 90 km/h, raising the risk of flash flooding and property damage.
- Cordillera alerts for Neuquén, Río Negro and Chubut expect 10–30 mm of rain with local exceedances and possible mixed rain–snow at higher elevations, and bulletins include province-level valid windows such as Misiones 03:00–08:59 and Río Negro 03:00–14:59.
- Southern Mendoza faces Zonda winds with sustained speeds of 30–50 km/h and gusts above 70 km/h that can reduce visibility and produce sudden temperature rises, so residents should secure loose objects and avoid exposed travel.
- An 'alerta amarilla' warns of weather that can cause damage and temporary interruption of activities; the SMN urges people to stay in closed buildings unless travel is essential, avoid flooded streets, disconnect electrical appliances if water enters homes, and follow local updates for changing conditions.
