  • Forecasts call for 40–70 mm of rain in a few hours in affected areas, gusts up to about 60 km/h, frequent lightning and possible hail.
  • Alerts and impact forecasts focus on La Pampa, Córdoba, Santa Fe, Entre Ríos and Buenos Aires, with some outlets also noting Mendoza and San Luis.
  • SMN cites historical records showing storms near August 30 in roughly 57% of years, underscoring the seasonal likelihood of the Santa Rosa window.
