Torrential thunderstorms dumped more than 100 millimetres of rain in less than an hour on parts of north-eastern Spain late Saturday, triggering flash floods across Catalonia and neighbouring Aragon, according to the State Meteorological Agency AEMET, which had issued its highest red alert. The coastal municipality of Cubelles, 50 kilometres south of Barcelona, was hit hardest. Firefighters backed by police, maritime rescue crews and drones are searching for an adult and a child believed to have been swept away around 9 p.m. when the fast-rising River Foix overflowed a wooden footbridge. Floodwaters inundated streets, shops and the Hospital Comarcal del Alt Penedès in Vilafranca, where 71 patients were transferred after a power outage. Rail operator Renfe halted all services in Catalonia for several hours, leaving about 150 passengers to spend the night at Barcelona’s Sants station before limited service resumed. Emergency services said they treated more than 70 people, none with severe injuries, while about 70 firefighters and army emergency units were deployed for rescues and clean-up. Authorities in Aragon lowered their emergency alert on Sunday as rainfall eased, but Catalan officials kept restrictions in place and urged residents to avoid rivers and flooded areas. Meteorologists said the isolated high-altitude depression that fueled the storms has moved into the Mediterranean, with clearer skies and rising temperatures expected early in the week.
