Flooding hit Valencia and Barcelona on Wednesday night, prompting authorities to send urgent ES-Alert warnings to thousands of mobile phones. Emergency services dealt with a surge of incidents as neighborhoods faced rising water and sudden disruption.
In Valencia, the Centro de Coordinación de Emergencias activated the Plan Especial de Inundaciones after hours of heavy rain swept across the city and its suburbs. The alert, sent at 22:08, told residents to avoid travel, stay clear of riverbeds and ravines, and move to higher floors if water levels rose. It targeted the province’s northern and southern coastal areas, where flood risk was highest, information from the Generalitat Valenciana.
The municipality of Valencia had already activated orange-level emergency protocols and suspended outdoor sports events from 14:00 on September 15, ahead of the heaviest rainfall.
Rainfall totals reached extreme levels in some areas. Torrent recorded over 90 liters per square meter in just 45 minutes, information from the mayor, who described the situation as briefly critical. L'Eliana saw 85 liters, while Chiva, Riba-roja de Túria, Llíria, and Paterna also reported heavy accumulations. Emergency crews rescued people trapped in a fast-food restaurant. The Spanish State Meteorological Agency (AEMET) had issued orange warnings, forecasting up to 40 mm per hour and 80 to 120 mm in 2 to 3 hours, with possible hail and strong winds.
Transport was quickly affected. Adif reported delays on the C2 commuter rail line between Silla and Almussafes because of power failures. Metrovalencia faced widespread delays and partial closures on lines 1 and 2. Manises airport closed temporarily, diverting 12 flights before reopening later in the evening. Travelers were told to check with airlines for updates as conditions changed.
Murcia took further precautions as forecasts worsened. The regional government suspended classes in 15 municipalities, including Águilas, Lorca, Cartagena, and Mazarrón, after the State Meteorological Agency raised the rainfall warning to orange, with up to 50 liters per square meter possible in an hour. Early childhood centers, day centers, and social services for older people and people with disabilities also closed to reduce movement and risk. The University of Cartagena halted all in-person activities, including non-impressive subcontracted work.
The severe weather extended beyond Valencia and Murcia: Catalonia, including Barcelona and surrounding areas, was also under orange and yellow alerts, with forecasts of over 40 liters per square meter in 30 minutes and up to 90 liters in 3 hours. Authorities in several autonomous communities kept heightened warnings in place into the night, anticipating more heavy rainfall.
President Pedro Sánchez urged the public to follow emergency service instructions and rely on official sources for updates. The Generalitat Valenciana repeated its call to avoid unnecessary travel and heed road closures. In southern Valencia, a pre-emergency yellow alert was declared for the Poyo-Saleta ravines, affecting several outlying districts.
Students, teachers, and staff in affected areas were told to stay home, and absences for force majeure were considered justified. Schools that remained open were told to accommodate students if teachers could not reach their posts. The government asked residents to monitor official websites and social media for updates.
Spain continues to face extreme weather and its effects on daily life. The rapid escalation of alerts and the scale of the response show how vulnerable urban infrastructure is to sudden downpours. For more on how political and social crises can shift priorities in Spain, see this earlier breakdown.
The storm exposed the limits of local preparedness and the need for fast, coordinated action. With schools closed, flights diverted, and public transport disrupted, the consequences reached across affected areas. The rapid use of ES-Alert and emergency plans showed a system under strain but focused on protecting residents. Climate volatility remains a central challenge for Spain’s cities and regions, calling for continued vigilance alongside investment and clear communication from authorities.
