The Servicio Meteorológico Nacional issued an orange alert on July 31, 2026, for severe storms hitting the Buenos Aires metropolitan area [5].
The warning is critical because the projected intensity of the weather, including high wind speeds and heavy precipitation, poses a significant risk to public safety and urban infrastructure.
The alert covers the Área Metropolitana de Buenos Aires, including the city and its suburbs, as well as the northern and western sectors of the region and neighboring provinces [1]. Meteorologists expect intense rainfall occurring in short periods, accompanied by intense electrical activity [1].
According to the agency, wind gusts may exceed 90 km/h [1]. There is also a risk of hail falling across the affected zones [2]. Forecasts indicate that maximum accumulated precipitation could reach 80 millimeters [4].
"El Servicio Meteorológico Nacional advirtió que habrá más precipitaciones 'en períodos cortos de tiempo, con actividad eléctrica intensa'", the agency said [1].
Temperatures are expected to remain low, with a maximum of 14 °C projected for the city [6]. While some reports mention a combination of orange and yellow alerts for snow and wind in broader regions [7], the primary focus for the metropolitan area remains the orange alert for severe storms [3].
"El SMN renovó la alerta naranja para la Ciudad, el conurbano y una amplia franja del centro‑este; recomiendan minimizar la circulación", the agency said [2].
“Wind gusts may exceed 90 km/h”
The issuance of an orange alert indicates a high level of meteorological danger that requires active precautions. By advising the public to minimize movement, the Argentine government aims to reduce the number of casualties and traffic accidents caused by sudden flooding and wind-blown debris in one of the world's most densely populated urban corridors.
