On 2026-10-19, a weather system identified as Adam moved over Spain’s Mediterranean coast, bringing intense rainfall that quickly turned streets into rivers. The system’s arrival triggered immediate alarm among local authorities.
Weather stations recorded staggering totals. In the town of Pego, accumulated rainfall reached 638.5 litres per square metre, while nearby Forna logged 635.2 litres per square metre, equivalent to 27.8 inches of rain. In Oliva, gauges measured 530 litres in a single day, and Pego saw 620 litres over the same period. These figures far exceed the typical daily rainfall for the area and help explain why the ground could not absorb the water.

As water levels rose, the Generalitat Valenciana issued orders for residents to remain indoors. Soon after, officials announced the evacuation of over 387,000 people from 61 municipalities spanning Valencia and Alicante. The operation included the removal of roughly 2,000 individuals from campsites in Oliva, where floodwaters had inundated temporary shelters. School closures affected about 100,000 students, keeping classrooms empty as authorities prioritized safety.
The Guardia Civil and local firefighters coordinated rescue missions, reporting critical situations in Oliva and Pego.
Emergency crews sprang into action. Helicopters were activated to reach those stranded on rooftops, while boats navigated flooded streets to pull families from submerged homes. The Guardia Civil and local firefighters coordinated rescue missions, reporting critical situations in Oliva and Pego. At the second‑highest emergency level, regional authorities deployed military units to assist with evacuations and to keep supply lines open.
Storm Adam is a complex system made up of two upper level lows creating instability in the western Mediterranean. Extreme rainfall due to thunderstorms is likely in Spain before spreading across France and Italy in the next few days. Be aware of flash flooding! Graphics by @aguacerowx
The storm claimed at least two lives. Rescuers continued to find people trapped on roofs and in upper floors, with one eyewitness, Juan Carlos Valderrama, describing "horrifying scenes" as he watched occupants cling to rooftops while water rose around them.
While rescues were underway, the Generalitat Valenciana worked on formalising a confinement order to be published in the DOGV, the region’s official gazette. The order aimed to restrict movement and keep civilians out of harm’s way as floodwaters persisted. Authorities repeatedly urged the public to avoid unnecessary travel and to stay inside until the danger passed.
SPAIN HIT BY VIOLENT FLASH FLOODS AS CARS ARE SWEPT AWAY AND RESCUES ESCALATE Torrential rainfall from Storm Adam is wreaking havoc across parts of Spain, sending powerful torrents through streets, sweeping away vehicles and inundating homes and businesses! Authorities have reported 155 storm-related incidents across Andalusia, including 121 in Almería, with 32 rescue and assistance responses and sections of the A-7 motorway forced to close! With roads submerged, major highways disrupted and emergency crews racing to assist stranded residents, communities across the region are facing dangerous conditions as the storm continues! Could this be just the beginning of an even bigger flooding emergency across Spain? #MrMBB333 #Spain #StormAdam
By the end of the day, floodwaters had cut off at least six towns, severed roads, damaged vehicles, and left significant property damage across the affected zones. The emergency response remained active, with crews still conducting evacuations and assessing the scale of destruction. The event stands as one of the most severe rain‑related incidents in recent memory for eastern Spain, highlighting the destructive potential of a stalled DANA system.
