Renfe stopped commuter trains in Valencia on October 1 after AEMET, Spain's meteorological agency, issued a red alert for violent storms. The suspension began at 18:00, affecting thousands of daily commuters and covering Cercanías, Media Distancia and some long-distance trains heading toward Catalonia. As severe weather hit the eastern coast, many passengers scrambled to find other ways to travel.
Cold air clashed with humid Mediterranean winds, bringing sudden, heavy rain. AEMET kept its highest-level warnings in place for Tarragona and Castellón, where rainfall could reach 90 litres per square metre in one hour. Some places might get 250 litres in half a day, enough to flood low-lying neighborhoods, dry riverbeds and city streets unbuilt for this kind of storm. The basic Cercanías lines affected were C1 (Valencia-Gandía), C2 (Valencia-Xàtiva-Moixent), C3 (Valencia-Buñol-Utiel) and C6 (Valencia-Castellón). EFE and Euronews reported these details from Renfe's official updates.
The danger extended south. Valencia and Alicante faced forecasts of up to 60 litres per square metre in a single hour along the coast. Murcia, Ibiza, Formentera, Almería and Granada received advisories for heavy rain and storms. As the day went on, the unstable weather was expected to move inland toward Madrid, Castilla-La Mancha, Castilla y León, Aragón and Extremadura. Madrid could also get 20 litres per hour, with hail and strong winds possible. AEMET bulletins cited by national media said the worst was likely late on October 1 and into Friday, October 2. The heaviest rain was expected to move toward Catalonia and the Balearic Islands.
Renfe's cancellations, prompted by the red alert, affected several lines in Valencia and routes to Catalonia. The company did not release a full list of affected trains. Flash floods and landslides can strike quickly, putting rail operations at risk. The timing left travelers facing a difficult situation: the region's basic transport routes stopped just as the storm front strengthened. Local and national news reported on the morning of October 2 that red warnings and travel restrictions remained in place. Renfe said it would restore service gradually as the weather improved.
AEMET expects the worst rain to move toward Catalonia, the Balearic Islands and other Mediterranean areas on Saturday. By Sunday, a high-altitude isolated depression, a dana, could settle west of the peninsula, bringing more showers and storms into the next week. The forecast remains uncertain. Current models suggest unstable weather could last through midweek, though conditions would be less severe than they are now.
The shutdown comes amid a pattern of increasingly wild weather in Spain in recent years. Earlier this year, sudden temperature swings and violent storms swept the country, as covered in the previous report. Along the Mediterranean, the shift from late-summer heat to autumn storms can happen quickly.
Renfe acted quickly after AEMET's red alert. The shutdown disrupted travel and was intended to protect passengers and rail infrastructure from flash floods and storm damage. The cancellations show how exposed Spain's transport network is to extreme weather and why emergency plans need to improve as climate patterns become less predictable. Travelers in eastern Spain face a weekend of delays and uncertainty as the rain continues.
