Overview
- The Servicio Meteorológico Nacional placed several provinces under yellow alerts for storms and rain, with the warnings covering parts of extreme northwest Córdoba and the south of La Rioja on Saturday 17 October 2026.
- The SMN warned of persistent moderate to locally strong rain with possible embedded storms, frequent lightning and gusts, and rainfall accumulations generally in the 20–40 mm range with isolated exceedances.
- Local civil-protection officials in San Luis Río Colorado issued wind and dust advisories after forecasts showed gusts that could reach about 55 km/h and create tolvaneras, and they gave safety advice such as avoiding travel and covering nose and mouth in dust events.
- Meteorologists say a blocking high-pressure pattern has kept the country cloudy and unstable for days but should weaken this weekend, producing a short-lived respite and a marked temperature drop in the AMBA with morning lows near 7°C.
- Authorities urged people to secure loose objects, stay indoors during storms and avoid flooded streets because the yellow alerts raise the risk of localized flooding and travel disruption, and forecasters expect instability and showers to return by mid to late next week.
