Storm Adam killed two women in Spain this weekend as the season’s first high-impact Mediterranean weather bomb swept torrential rain across the Balearic Islands, Valencia and Catalonia, closing Ibiza’s airport, mobilizing the army and forcing tens of thousands of children to stay home on Monday.
The storm — a phenomenon meteorologists call a DANA, a “cut-off low” in which a pocket of cold air detaches high in the atmosphere and collides with warm, humid Mediterranean air — triggered some of the most violent flash flooding Spain has seen this autumn. Spain’s state meteorological agency, AEMET, had issued red warnings, its highest alert level, for the southern coast of Valencia province and northern Alicante, with orange warnings stretching from Catalonia to the Balearics and into southern France.
The first victim was a 35-year-old woman from Cabrera de Mar, about 27 kilometers north of Barcelona. She was swept away by a swollen stream on Saturday evening as she tried to cross it with her children, in full view of her young daughter. Firefighters found her body on Sunday at the port of the neighboring town of Premià de Mar. The municipality of Cabrera de Mar declared Monday, October 19, an official day of mourning and held a minute of silence in her memory.
The second woman drowned on Sunday night at Almardá Beach in Sagunto, north of Valencia, after going for a swim while an orange storm alert was in force. Her Dutch husband managed to get out of the rough water and raised the alarm around 8 p.m. Police, firefighters and coastguards launched a search, later scaled back by deteriorating sea conditions; her body was found shortly afterwards on the nearby beach of Canet d’en Berenguer.
The storm’s impact was felt hardest on the islands. On Ibiza, 121.3 millimeters of rain fell in 24 hours, and the main airport was shut down for about two hours around midday on Sunday after the runway became inoperable and water poured through a leak in the terminal’s roof. A total of 27 flights were cancelled and 16 diverted. In Formentera, a staggering 97.4 millimeters fell in a single hour on Saturday evening. Spain’s Military Emergency Unit, the UME — the armed forces’ specialist disaster-response corps — was mobilized from its Valencia base on Sunday morning, pumping waist-high water out of flooded garages in Ibiza and reinforcing overwhelmed local services on Mallorca.
On the mainland, the worst downpours hammered southern Valencia province, northern Alicante and parts of Catalonia. In Rafelcofer, rainfall reached 230 millimeters, and forecasters warned some locations could see up to 300 millimeters in less than 24 hours. About 87,000 students in the Valencian Community faced cancelled or restricted classes on Monday, with schools and university campuses closed across Mallorca, Ibiza and Formentera. Hundreds of thousands of residents were told to stay indoors, and lorries were left stranded on the N-332 motorway near Gandia as floodwater swallowed the road.
The storm’s upper-air center sat over France on Monday morning, but its trailing influence kept torrential rain and thunderstorms battering eastern Spain. AEMET expects conditions to begin improving on Tuesday, October 20, though forecasters warned against assuming an ended warning means safe roads: saturated ground needs time to drain. Heavy showers were expected to shift toward Catalonia during the afternoon, putting Barcelona and coastal communities under flash-flood threat.
Adam was officially named by AEMET on October 16, making it the first high-impact DANA of the 2026-27 season. France, too, was feeling the edges of the system: five departments in the south — Bouches-du-Rhône, Gard, Hérault, Lozère and Var — were under orange weather warnings on Monday, with Meteo-France warning that up to 300 millimeters of rain could fall in parts of Gard and Hérault.
Why this matters: DANAs are a recurring autumn menace on Spain’s Mediterranean coast, but Adam’s arrival carries extra weight. It struck just as the region was recovering from a summer of devastating wildfires, and it fell at the tail end of the holiday season on islands whose economies live or die on tourism — a flooded airport runway is not only an emergency but an economic wound. For the wider Mediterranean, the pattern is becoming familiar and harder to ignore: warm sea-surface temperatures pump moisture into these cut-off lows, and what used to be exceptional downpours are testing infrastructure — drainage, airports, emergency services — designed for a gentler climate. Two women are dead before the system has even left; how Spain’s warning systems handled Adam will be scrutinized for months.
Spanish authorities urge residents in affected zones to follow the AEMET weather warnings and avoid non-essential travel until red and orange alerts are lifted.
