The state meteorological agency AEMET warns of very heavy and prolonged rainfall on Spain’s east coast on 1 October 2026. The areas affected include parts of the provinces of Valencia, Castellón and Tarragona. Official forecasts refer to locally extreme rainfall; in some areas, peaks of up to 250 litres per square metre in twelve hours cannot be ruled out. Depending on conditions, the authorities expect flooding, flash floods and traffic disruption.
On Thursday, the city of Valencia activated its highest-level emergency protocols and convened the municipal coordination centre CECOPAL . According to the city council, public parks and beaches were closed, targeted school closures were ordered and parts of educational activity were suspended as a precaution. Traffic is also being diverted around areas at risk of flooding; the city advises avoiding low-lying stretches of road and travelling only in urgent cases.
Authorities have also responded in Catalonia. In the provincial capital, Tarragona, the alert phase of the municipal flood action plan was declared. Catalonia’s civil protection service Protecció Civil sent an ES‑Alert to several coastal districts to inform the public in advance. Regional and municipal services have referred to prepared evacuation routes and are increasing staffing and on-call cover for fire, police and emergency services.
The warnings are based on AEMET notices published on Thursday and supplementary statements from the administrations concerned. They apply at different alert levels depending on the area. The situation is changing; depending on the path and intensity of the storm cells, the worst-affected areas may shift during the day. Experts stress that brief periods of very intense rain can cause water levels to rise sharply in local areas – particularly in depressions, underpasses and along riverbanks – and advise against crossing flooded areas.
The authorities have highlighted basic safety advice: move to higher, safe ground, keep your phone available for emergencies, follow instructions from emergency services and do not return to affected areas until they have been officially cleared. Administrations are providing ongoing updates on changes to alert levels and measures through their channels.
As things stand, reports concerning heavy rain, emergency plans and restrictions are based on official statements issued on 1 October 2026. Further updates may follow during the day.
