Briefing
On Monday 5 October 2026, line-organised thunderstorms and very heavy showers in Barcelona as well as traffic disruption, flooded underpasses and waterlogged basements in parts of the Litoral and Prelitoral. The state weather agency Agencia Estatal de Meteorología (AEMET) and the Catalan Servei Meteorològic de Catalunya (Meteocat) issued official weather warnings for affected areas and monitored the situation continuously. Protecció Civil of the Generalitat de Catalunya activated the Centre de Coordinació Operativa de Catalunya (CECAT) and sent ES-Alert messages to residents in particularly vulnerable areas such as the Vallès Oriental and the Maresme.
Emergency services reported a high number of calls about flooded roads and blocked routes; this led to local closures and restrictions on public transport, including in the vicinity of Granollers and parts of the Barcelonès. Municipal services deployed pumps and machinery to keep drains clear and secure hazardous areas. Authorities lifted temporary protective measures, but continued to advise caution and compliance with local instructions.
Meteorologists explained that the situation had been fuelled by a moist, high-energy air mass over the western Mediterranean, which produced stationary or slow-moving storm cells. Official situation reports did not classify the system as a tropical cyclone; experts noted that such a classification requires separate analytical criteria.
AEMET and Meteocat continued to monitor the situation over the coming hours and warned of further locally very intense showers. Protecció Civil advised people to avoid underpasses, not to park vehicles in low-lying areas and to follow official warnings. Authorities named restoring transport routes, documenting damage and maintaining warning communications between weather services, emergency responders and municipalities as immediate priorities.
