Overview
- The Servicio Meteorológico Nacional issued orange and yellow warnings for many provinces on Thursday for hazards that include strong convective storms, heavy rain, high winds, Zonda and cordillera snow.
- Authorities warned the Buenos Aires metropolitan area and nearby provinces face intense short-term rainfall of about 50–80 mm, hail and gusts that can exceed 80–90 km/h during the main alert windows.
- The cordillera of Mendoza has an orange alert for heavy snowfall with expected accumulations of roughly 40–70 cm and episodes of Zonda winds that can produce sudden warming, low humidity and gusts over 70–80 km/h.
- Local governments and the SMN urged people to avoid nonessential travel, secure loose objects, not put out garbage, prepare emergency supplies and expect possible disruptions to power, transport and drainage systems.
- Forecasters say the same cyclogenetic system will bring a marked cooling after the front passes, with much colder mornings and lower daytime highs forecast from Friday through the weekend, following recent unusual July rainfall linked to the strong Niño pattern.
