Argentina’s National Meteorological Service (SMN) has issued yellow alerts for heavy storms across multiple provinces, with significant weather disruptions expected in the Buenos Aires metropolitan area and the Litoral region.
The Cause of the Severe Weather
According to local media reports, the current weather pattern is being driven by a process of cyclogenesis. This meteorological phenomenon is expected to trigger widespread rainfall across the Litoral region of Argentina, leading to the issuance of yellow alerts by the SMN to warn of potentially strong storms.
Impact on Buenos Aires and AMBA
The City of Buenos Aires (CABA) and the Greater Buenos Aires area (AMBA) are facing a return of intense rainfall. Reports indicate that the region is bracing for 48 hours of continuous rain, with the most significant impact forecasted to occur over the weekend.

The SMN has extended the yellow alert for storms to cover the entire territory, signaling a high likelihood of heavy precipitation and unstable weather conditions for residents in these urban centers.
Regional Alerts and Scope
While the capital is a primary focus, the weather warnings are not limited to the metropolitan area. According to reports from regional outlets, the yellow alert currently spans several provinces, ensuring that a broad section of the country is on notice for heavy storms and potential flooding associated with the ongoing weather system.
