Core Event – Fatal Flooding on October 4, 2026
Heavy rainstorms on the morning of October 4 caused rivers to overflow in Catalonia. Two men died: one in Tordera when a campsite wall collapsed, and another in Montornès del Vallès after a flooded garage submerged him. Emergency crews continued searching for a missing person in Pineda de Mar. Authorities classified the situation as “extreme danger” and urged residents to stay indoors.
Background & Context
Meteorologists identified the storm as a “mini-hurricane”-like mesoscale convective system (DANA). Such events occur when cold upper-air masses meet warm, moist air from the sea, producing intense thunderstorms. Catalonia suffered a similar DANA in October 2024 that killed 238 people; a 2026 study linked that disaster to climate change, highlighting the heightened risk of extreme rainfall.
Timeline
- Sept 29 – Torrential rains disrupted commuter rail, metro lines and caused airport delays in Barcelona.
- Oct 3, 8 p.m. – The Generalitat activated an ES-Alert and imposed mobility restrictions across 20 coastal counties, limiting travel until 2 p.m. on Oct 4.
- Oct 4 (morning) – Red alerts remained; the two fatalities were confirmed and the missing-person search continued.
Data & Statistics
- Rainfall exceeded 250 mm in parts of the Terres de l’Ebre; L’Ametlla de Mar recorded 264 mm, the highest among Meteocat stations.
- The Besòs River peaked at roughly 937 m³/s near Santa Coloma de Gramenet, prompting additional alerts.
- Civil Protection logged 242 emergency calls, generating 169 incident files.
- Firefighters conducted 128 vehicle rescues and over 300 storm-related actions.

Official Statements & Responses
- Salvador Illa, President of the Generalitat, expressed condolences and warned the situation remained “complicated,” urging “maximum caution.”
- Sarai Sarroca, director of Meteocat, described the system as an exceptional “mini-hurricane” capable of delivering more than 90 L of rain per square meter in three hours.
- Imma Solé, deputy director of Civil Protection, said saturated ground could not absorb additional water and urged residents to avoid low-lying areas.
- Oriol Corbella, head of Catalan firefighters, reported extensive rescue operations, including 18 vehicle rescues on Friday morning.
On-the-Ground Reports
Residents in Tordera and Montornès del Vallès reported flooded garages, collapsed walls and swept-away vehicles. In Granollers, crews rescued people trapped in cars, some of whom took refuge on rooftops. Rodalies rail services were suspended, and Barcelona-El Prat airport faced flight cancellations. Shops closed early and a performance of Verdi’s *Aida* at the Liceu was cancelled.
What’s Next
Mobility and activity restrictions remain until 2 p.m. on Oct 4, after which the Generalitat will reassess the situation. Meteocat expects conditions to improve in the afternoon, but Civil Protection warns that saturated soils could trigger additional flash floods or landslides if another intense storm arrives. The Inuncat emergency plan stays active, and officials continue to monitor river levels, especially the Besòs, while urging the public to stay indoors and avoid non-essential travel.
