Spain’s national weather agency, AEMET, has issued a red alert, the highest level of warning for parts of Cataluña, with Barcelona’s inland depression zone facing an extreme risk of flash flooding due to torrential rainfall.
The alert issued on Tuesday warns of rainfall that could reach 60 litres of water per square metre can be achieved in only one hour. Up to 120 mm can fall in less than four hours. These volumes pose a serious flash flood risk, especially in low-lying rural and urban areas. The most severely affected zone is the Depresión Central de Barcelona, which includes interior parts of the province rather than the city centre alone. The regional protección civil service has activated the INUNCAT flood emergency plan, urging residents to remain indoors, avoid unnecessary travel, and steer clear of rivers, basements, and underpasses. Emergency services have been put on high alert because storm activity will continue throughout the week.
