The State Meteorological Agency has issued a red alert for torrential rain along the southern coast and pre-coastal areas of Tarragona. This measure is in response to an episode of very intense rainfall linked to Storm Alice, which, according to the forecast, could bring heavy downpours to the Ebro Delta region during Sunday afternoon and evening.
The red alert level indicates extreme risk in exposed areas: flash floods, urban drainage problems, and mobility disruptions are possible. Forecasts predict peak rainfall of around 90 mm in one hour and totals that could reach up to 180 mm in 12 hours , with showers accompanied by thunderstorms and significant local variability.
What the red warning means and why it is activated
The declaration of a red alert means that authorities consider an extraordinary impact on the population and property likely if the most severe scenarios materialize. In these types of events, downpours can be highly localized and leave large accumulations in a short time, leading to flash floods in streams, ravines, and low-lying areas of the road network.
Aemet raises the alert level to its highest point when several factors converge: high rates of precipitation in short periods, a highly unstable atmosphere, already saturated soils, and orographic effects that intensify rain bands. In southern Tarragona, the coastal terrain and the dynamics of the cut-off low contribute to this intensification.
Civil Protection has sent an ES-Alert to mobile phones in the Montsià region , reminding people of the need to take extreme precautions, avoid unnecessary travel and not approach watercourses, streams or flood-prone areas.
In addition to the downpour, there may be occasional strong gusts associated with storms and rough seas on the coast, factors that complicate emergency management and circulation in coastal and transition areas towards the pre-coastal zone.
Affected areas and planned time slots
The warning focuses on the southern coast of Tarragona and its pre-coastal area , with particular attention to Terres de l'Ebre and the delta region, where orographic lift and lines of instability could produce the heaviest rainfall. The most vulnerable period extends from Sunday afternoon until night .
For Monday, the forecast anticipates continued instability, but with less severity: an orange alert remains in place on the southern coast of Tarragona between 10:00 and 23:00, with showers still intense, although generally somewhat more contained than during the most critical hours.
The atmosphere will remain very heavy in the NE of the peninsula, with very cloudy skies , stretches of persistent rain and possible residual storms, especially during the first half of the day and in mountain areas and near the coast.
Meanwhile, Aemet maintains lower-level warnings in other Catalan regions , depending on how the bands of precipitation associated with the DANA and the humid easterly flow evolve.
Notable incidents: roads and railways
The rains have caused road flooding and traffic disruptions. The Catalan Traffic Service has reported the closure of the AP-7 motorway between Freginals and Ulldecona in both directions, establishing mandatory detours at points such as l'Hospitalet de l'Infant (southbound) and Ulldecona (northbound).
Several secondary and national roads have also been interrupted or restricted: C-12 between Amposta and Tortosa (with signposted detours), T-331 between Ulldecona and Santa Bàrbara , TP-3311 between Santa Bàrbara and La Sènia and the N-340 between Amposta and Alcanar , among other specific disruptions.
On the railway, water accumulation on the tracks has forced the suspension of service on the R16 line and the cancellation of departures on the Mediterranean corridor to Barcelona and Valencia. The incident has affected more than 3.000 passengers and around twenty trains, with route changes, trains returning to stations, and some cancellations.
Renfe has announced that tickets for affected routes can be changed or cancelled free of charge . Civil Protection has activated the pre-alert phase of the Ferrocat plan for rail passenger transport.
The Generalitat Fire Service has responded to a growing number of calls regarding flooding in basements , water accumulation, and vehicle rescues, exceeding 170 services between the afternoon and early evening, with the Montsià region being the most affected.
Civil Protection Measures and Recommendations
With the red alert in effect, authorities are urging people to avoid travel unless absolutely necessary. If you are already on the road, they recommend checking road conditions, avoiding crossing flooded areas , and exercising extreme caution in underpasses and areas prone to flooding.
The public is advised to stay away from rivers, streams, and ravines ; remove vehicles from flood-prone areas; and secure objects on balconies or patios that could be swept away by water or wind. In case of emergency , call 112 and follow the instructions of the emergency services.
The ES-Alert message issued in Montsià emphasizes the importance of staying in safe places, postponing outdoor activities, and following official channels for updates on warnings or new incidents.
In affected municipalities, local councils have rescheduled activities and, as a preventative measure, school activities on Monday, October 13, have been suspended in the most exposed areas to reduce mobility and ensure safety.
The evolution in the next few hours
Looking ahead to the early hours of Monday, the weather is expected to remain changeable, with periods of rain and abundant cloud cover. The weather situation will continue to be monitored, with an orange alert in effect for the southern coast of Tarragona during the daytime hours specified by the weather agency.
In these types of storms, the spatial dispersion of the storms means that the accumulated rainfall varies greatly over a few kilometers, so it is crucial to pay attention to municipal and regional warnings , in addition to the general report from Aemet.
If there is no need, the most prudent thing to do is to avoid travel during peak risk times, postpone outdoor tasks, and regularly check official updates on Civil Protection and Aemet channels.
The combination of an exceptional red alert , the incidents already recorded on roads and railways, and the possibility of new storms makes it advisable to maintain a vigilant attitude, reducing exposure and prioritizing safety while the storm subsides.
