Severe Storm Triggers Floods and Debris Flows in Ourense Mountains

Land stripped by 2025 wildfires plus piled timber turned an intense June storm into destructive debris flows that forced evacuations and prompted urgent road clearing and damage assessments.

Overview

  • An intense thunderstorm on Wednesday produced torrential rain, hail and winds that caused flash floods and violent debris flows in mountain areas of Ourense, forcing evacuations but causing no reported deaths.
  • The worst damage concentrated in Viana do Bolo (A Bouza, Pradocabalos, Pexeiros, O Castro) and parts of Vilamartín de Valdeorras (Arcos, Farelos), where homes, vehicles and farm buildings were inundated or swept away.
  • Key routes and small bridges were cut or damaged, including the N-120 and stretches of the OU-533, OU-0903 and OU-0904, and water and telephone services remain compromised in several villages.
  • Provincial and regional authorities have deployed heavy machinery and brigades to clear roads, are organizing peritajes and damage assessments, and local leaders are demanding activation of emergency plans and rapid financial aid.
  • Officials and residents say the scale of destruction was amplified by leftover burned wood, ash and stacked logs from the 2025 wildfires, a factor that raises the risk of further damage if more heavy rain arrives and makes recovery long and costly.
