Overview
- The Servicio Meteorológico Nacional issued a yellow alert for thunderstorms on Wednesday covering parts of Buenos Aires province, Tucumán, Salta, Santiago del Estero and the eastern sector of La Pampa.
- The alert lists hazards of heavy short‑period rainfall, frequent lightning, strong wind gusts and occasional hail with expected accumulations around 20–40 mm in affected areas.
- The AMBA (Buenos Aires metro area) will see showers late Wednesday and a main window of instability on Thursday according to SMN forecasts, while local meteorologists in Salta say cold, humid and storm‑prone conditions will persist through Thursday.
- Regional forecasts show strong contrasts: Córdoba, Mendoza and parts of the Litoral and Patagonia can expect clearer, warmer days while the northwest provinces face continued rain and isolated storms.
- Forecasters and local agencies advise avoiding outdoor activities during warnings, securing loose objects and keeping drains clear, and most services project a notable decrease in instability with warmer, sunnier weather from Friday into the weekend; a separate report notes warm conditions in Catalunya driven by North African air before a cold front brings cooler temperatures on Thursday.
