A severe storm struck the Buenos Aires Metropolitan Area and surrounding towns during the early morning and morning of Saturday, October 25, 2025, bringing over 100 millimeters of rain, power outages, and structural damage. The storm led to flooding, fallen trees, and transport delays under an orange alert from the National Meteorological Service. In San Martín, a house collapsed, trapping a mother and her son.
The storm began in the early morning of October 25, 2025, mainly affecting the AMBA, including the Capital Federal and Buenos Aires suburbs, as well as cities like La Plata, Junín, Benito Juárez, Pergamino, and Quilmes. In La Plata, 100.3 millimeters of rain fell in Melchor Romero in under 48 hours, leaving streets impassable and trees down, such as on calle 46 between 5 and 7. In Quilmes, 115 millimeters fell in 24 hours, with 76 millimeters between 3 and 7 a.m., worsened by the sudestada on the Río de la Plata.
Wind gusts reached up to 87 kilometers per hour in Benito Juárez, destroying the roof of the main hall at Club Jorge Newbery, with twisted metal beams. In Junín, winds near 90 km/h blew off the covered pool tent at Club Junín, leaving over 15 neighborhoods without power. The club president said: “It's an enormous anguish”.
In the AMBA, more than 30,000 users lost electricity, with 11,462 affected by Edenor and 21,597 by Edesur, especially in the southern suburbs and some porteño neighborhoods. A City Bell resident recounted: “We were without power from 2 a.m. until noon”. “The problem is that we depend on pumps, and when there's no power, we have no water either”.
Public transport faced disruptions: the Ezeiza branch of the Roca railway operated limitedly due to flooding in Turdera, and the Cañuelas-Lobos branch was suspended. In San Martín, a house in Villa Maipú collapsed due to the storm; Silvia, an insulin-dependent diabetic woman, and her son were rescued by firefighters. She said: “I lost everything, I'm left with what I have on”. “It was a great miracle”, she added, as her son woke her in time.
Authorities are monitoring the situation for possible further rain, with teams working on service restoration and drain cleaning.
