Sudden Downpour Soaks Greater Buenos Aires: Panamericana Reopens as Unicenter Shortens Hours

Authorities opened reviews of drainage performance after a brief, intense 'air storm' overwhelmed parts of the northern metro area.

Overview

  • Autopistas del Sol reported nearly 100 mm of rain in about an hour and said all Panamericana branches and General Paz were passable after overnight cleanup with cranes, sweepers and crews.
  • Unicenter reopened with restricted hours from 9:00 to 18:00 as technical teams continued repairs, with some stores remaining closed for safety checks and reconditioning.
  • Provincial Civil Defense said around 30 people were rescued from submerged vehicles, with flooding focused on stretches near San Martín, Martínez and San Isidro.
  • Meteorologists characterized the event as a highly localized 'tormenta de aire,' with totals of roughly 80–100 mm in under an hour and short‑term alerts issued by the national weather service.
  • Coverage now centers on drainage capacity and maintenance, with responsibilities split between AUSOL on the highway and provincial agencies for neighborhood relief channels, alongside resident claims of delayed gate operations.
