An orange weather alert has been issued for the Buenos Aires Metropolitan Area (AMBA) and multiple regions across Argentina as a severe storm system brings heavy rainfall, frequent lightning, intense winds, and localized hail.
Orange Alert Declared Across the AMBA and Surrounding Provinces
Severe weather conditions tied to the developing weather pattern have prompted official warnings from meteorological authorities. According to Meteored Argentina, the Servicio Meteorológico Nacional (SMN) activated an orange alert—the second-highest level on the scale—signaling not just potential disruptions, but phenomena capable of putting lives at risk. The active warnings span the southern portion of Entre Ríos, southern Santa Fe, Córdoba, the northwest of La Pampa, and northern Buenos Aires, as reported by Infobae. Additionally, Neuquén, Chubut, and the south of Buenos Aires are under a yellow alert, while the mountainous region of La Rioja, Catamarca, Salta, and the east of Buenos Aires face a yellow alert for strong winds, and the west of San Juan and Mendoza face a yellow alert for snow.

In Rosario, the storm hit forcefully during the morning hours. Rosario3 reported that the city experienced a sudden darkness mid-morning accompanied by heavy rain, thunder, and falling hail, altering daily routines and transit across the center. Meanwhile, Diario El Día de La Plata noted that municipal officials in La Plata escalated their local alert to orange ahead of incoming downpours expected to bring wind gusts of up to 50 kilometers per hour. The municipality elevated the alert at the end of Tuesday afternoon, and a Municipal Emergency Committee meeting was expected to gather at 8 in the morning.
Rainfall Accumulations and Wind Forecasts
Precipitation rates are expected to test urban drainage systems throughout the affected zones. Meteorological projections cited by Meteored indicate that peak rainfall totals could reach between 50 and 80 millimeters in certain areas, potentially causing localized flooding and water pooling on roadways. In the AMBA specifically, Infobae noted anticipated accumulations near 20 millimeters alongside wind gusts ranging between 42 and 50 km/h as a cold air mass moves into the region. Temperatures in the AMBA are expected to reach a low of 14°C and a high of 19°C during the afternoon, with precipitation potentially intensifying during the afternoon and night. Unstable conditions are set to persist into Thursday with isolated rains, followed by Friday when the wind rotates to the southeast with gusting, abundant cloudiness, and temperatures barely exceeding 17°C with a minimum of 13°C. Saturday may see conditions deepen due to a possible sudestada over the Río de la Plata with sustained winds and returning instability, while Sunday and Monday are forecast to stay cloudy with highs near 19°C.
