Overview
- The national weather service, which kept orange and yellow alerts in place on Saturday, warned of 80–110 mm of rain in southeast Buenos Aires and gusts over 70 km/h, with yellow wind alerts stretching into several central and northern provinces.
- In the AMBA, Saturday brought 7–13°C temperatures, steady southwest winds of 35–50 km/h, and gusts near 70 km/h, while coastal areas faced stronger bursts up to 80 km/h.
- Mar del Plata authorities formed an emergency committee, closed the south breakwater, and suspended port and recreational nautical activity to reduce risk from high winds and rough seas.
- The SMN urged people to stay indoors if possible, secure loose items, avoid windows, and disconnect appliances if water enters, noting risks of falling objects, reduced visibility, and power disruptions.
- Cyclogenesis, the rapid strengthening of a low‑pressure system, can pull in colder air, deepen winds on land and at sea, and prolong periods of rain before weakening as the center moves offshore early next week.
