Authorities in Catalunya warn of a possible Mediterranean hurricane, with over 200 l/m2 of rain and dangerous winds expected. Emergency alerts and restrictions could affect millions across the region.
Phones will buzz with warnings this afternoon in parts of Catalunya. Meteorologists say a rare Mediterranean hurricane, or medicane, could hit the region with more than 200 litres of rain per square metre in just six hours. Winds strong enough to trigger tornadoes and waterspouts are also possible. Civil Protection and the Servei Meteorològic de Catalunya (Meteocat) have called this an “exceptional episode.” The most dangerous window starts tonight and runs through midday Sunday.
Authorities will send Es-Alert messages to people in high-risk areas. The alerts target the central coastal comarcas, the northeast, and parts of central Catalunya. Specific zones include Alt Empordà, Alt Penedès, Baix Empordà, Baix Llobregat, Garraf, Garrotxa, Gironès, Pla de l'Estany, Selva, Vallès, Barcelonès, Alt Camp, Baix Camp, Baix Penedès, Osona, Ripollès, Moianès, and Tarragonès. The main concern is for the coastal and pre-coastal areas of Tarragona, Barcelona, and Girona. Flooding and wind damage are most likely there.
According to official reports from Meteocat and AEMET, red-level weather warnings have been issued for Camp de Tarragona, Penedès, and Ebre, with rainfall rates expected to reach up to 40 l/m² in just 30 minutes and 90 l/m² per hour in the most affected areas.
Meteocat director Sara Sarroca and forecasting chief Santi Segalà say all models now point to a medicane that could bring “significant downpours.” Rain has already started in some areas. It could get much worse, fast. Officials urge people to stay away from places known for flooding. They also ask everyone to rethink travel or outdoor plans. The government is preparing new restrictions from 8 p.m. tonight until midday Sunday.
Organisers of public events have been told to cancel activities with large crowds, outdoor exposure, or lots of movement. The highest risk is along the coast in Tarragona and Barcelona. Rainfall could hit 200 l/m2 there. Some inland areas are also at risk.
This level of emergency response is not new. Civil Protection has issued similar alerts before, including for heavy rain in Tarragona, as reported previously. But this storm stands out. The scale and intensity are different. Tornadoes and waterspouts are possible, making the situation even less predictable.
The current episode is not isolated to Catalunya: according to AEMET and several leading Spanish media outlets, the storm system has also affected Valencia and Castellón, with the risk zone expanding and persisting over several days. Authorities have warned of secondary dangers such as sudden river surges, thunderstorms, and local whirlwinds, emphasizing the need for ongoing vigilance.
Emergency services are on alert. The next few hours will show how ready they are—and how well the public listens. Mass alerts and calls to suspend public events show how serious the risk is. Spain is used to sudden weather changes. But a Mediterranean hurricane is rare. The real test will be how well people and officials adapt as the storm unfolds. The outcome depends on both the weather and the response.
