Overview
- - The Servicio Meteorológico Nacional, which issued orange and yellow alerts on Sunday, warned of strong to locally severe storms with frequent lightning, possible hail, gusts near 70 km/h and heavy rain across roughly 14–15 provinces.
- - Snow alerts target the southwest cordillera of Mendoza with 15–40 cm possible, while separate rain advisories extend into parts of Neuquén and the Malvinas, signaling high‑terrain travel risks and wet, windy lowlands.
- - The advancing cold front has already produced instability in the center and north, with Bahía Blanca seeing storms and a marked cool down on Sunday, Santa Fe forecasting showers by late day, and Tucumán expecting light rain by night.
- - In the Buenos Aires metro, forecasters call for isolated storms Monday, a sharper cool down Tuesday near 13°C/19°C, and drier air returning Wednesday, ending the humid spell that followed last week’s deluges.
- - Officials urge residents to avoid flood‑prone areas, secure loose items, disconnect power if water enters homes and carry winter gear in mountain zones, noting recent downpours tied to a cyclogenesis event already topped 100 mm in some districts and stressed drainage.
