Buenos Aires averages about 1,200 mm (roughly 47 inches) of rain a year, distributed fairly evenly across the seasons but punctuated by intense summer thunderstorm complexes that move up from the Pampas. These storms, sometimes organized into large, fast-moving squall lines locally associated with the “sudestada” wind pattern, can bring damaging wind gusts and torrential rain that overwhelms the city’s storm drains within a short period. The Riachuelo river and other waterways that cross the city have a history of overflowing during the heaviest events, affecting low-lying neighborhoods along their banks. Because these storm systems can develop over the pampas and reach the city within a few hours, radar tracking gives useful lead time compared with a standard multi-day forecast. Argentina’s national weather service, the Servicio Meteorológico Nacional, operates Doppler radar coverage for the greater Buenos Aires region from its site at Ezeiza.
