Overview
- The Servicio Meteorológico Nacional issued coordinated orange and yellow alerts on Tuesday covering as many as 16 provinces for storms and heavy rain.
- Orange warnings focus on parts of Corrientes, Santa Fe and Entre Ríos where the SMN forecasts 50–90 mm of rain, hail, frequent lightning and wind gusts that can exceed 100 km/h.
- Yellow alerts span Buenos Aires (including AMBA), Misiones, La Pampa, San Luis, Córdoba, Santiago del Estero, Tucumán, Chaco, Formosa, Salta, Jujuy and La Rioja with expected accumulations typically between 20 and 50 mm and possible hail and strong gusts.
- The SMN issued short‑term two‑hour nowcasts for specific localities in Corrientes and Misiones after radar detected active storm cells and repeatedly urged people to stay indoors, secure loose objects and avoid flooded streets.
- Forecasters link the episode to cyclogenesis over the east and note near‑El Niño conditions that can raise regional rainfall risks; authorities expect conditions to ease after Tuesday but warn localized flash flooding, infrastructure damage and travel disruption remain possible.
