Buenos Aires braces for heavy storms, hail, and up to 50mm of rain

Buenos Aires is bracing for a period of intense weather as July concludes and August begins. A significant deterioration in meteorological conditions is forecast from Friday, July 31, into Saturday, August 1. This shift follows a week of humid, cool weather with overcast skies and occasional light rain.

The peak of the instability is predicted for Friday night and early Saturday morning. During this time, heavy rains and strong thunderstorms are expected to develop. Meteorologists anticipate rainfall accumulations of around 50 millimeters, with the possibility of exceeding this amount in areas near the Río de la Plata. The precise timing and intensity of the phenomenon may still change due to the forecast's distance.

The weather event is linked to a surge of warm, humid air from the north, increasing atmospheric instability over central-eastern Argentina. The primary areas of concern include the city of Buenos Aires, its surrounding suburbs, and the broader Buenos Aires Metropolitan Area (AMBA). Some models suggest that the Río de la Plata region could see the highest rainfall totals.

Before this main event, Buenos Aires will endure several gray and cool days. Temperatures are expected to drop, with highs around 17°C on Tuesday and only 15°C on Wednesday. Eastward winds will also strengthen. Isolated drizzle is possible Tuesday night into Wednesday morning, with fog and mist potentially reducing visibility in the early hours of both days.
