Core Event: Flash Floods Sweep Catalonia and Valencia
Heavy rain on Wednesday night and into Thursday produced flash floods across Catalonia and Valencia. A red weather alert was issued for Barcelona’s coastline by AEMET, while Catalan authorities raised orange and amber alerts. The deluge swept a vehicle from a road near Olivella, about 40 km west of Barcelona, killing a middle-aged British man. Emergency services logged more than 850 calls in Catalonia and 478 incidents in Valencia, many involving property damage, road closures and transport interruptions.
Background & Context
The storms arrived as Spain emerged from its hottest summer on record, a pattern scientists link to climate change intensifying Mediterranean storms. The same system earlier produced record rainfall on Mallorca, where the Son Torrella station recorded 76.4 L m?² by early Thursday.
Data & Statistics
- Rainfall intensity: Over 70 mm (2.76 in) in half an hour in several Valencia municipalities; potential accumulations exceeding 40 L m?² in 30 minutes across parts of Catalonia.
- Emergency calls: Catalonia received more than 850 calls and logged over 500 incidents; Valencia reported 478 incidents.
- Transport impact: All Barcelona metro lines were suspended, buses diverted, and El Prat airport closed for hours, with 12 flights diverted. In Valencia, a La Liga match between Levante and Athletic Bilbao was postponed.
- Evacuations: About 270 people were evacuated from a campsite in Sitges.
- Mallorca rainfall: Son Torrella (76.4 L m?²), Lluc (55.4 L m?²), Binissalem (64.4 L m?²), Llucmajor (40.4 L m?²).
Official Statements & Responses
- Prime Minister Pedro Sanchez warned of “very complicated situations” and urged the public to avoid unnecessary travel.
- Civil Protection activated the INUNCAT emergency plan, advising residents to limit mobility and stay away from watercourses.
- Meteocat issued a level-6 violent-weather warning for Baix Llobregat, Garraf and Vallès Occidental, noting hail larger than 2 cm, wind gusts over 90 km h?¹ and possible tornadoes.
- AEMET cautioned that more than 100 L m?² could accumulate in two to three hours in the most affected eastern-peninsula areas.
On-the-Ground Reports
Fire crews responded around 11 p.m. on Wednesday (September 16) to a vehicle falling into water near Olivella. Divers and drones helped locate the victim about 500 m from the vehicle’s last known position. Residents in Catalonia, Valencia and Almería received mass telephone alerts, and many Barcelona streets were submerged, prompting closures of metro stations and Ronda de Dalt highway exits.
Conflicting Reports & Gaps
Initial coverage identified the missing flood victim as a woman; later updates clarified the deceased was a man. No further discrepancies were noted regarding casualty figures or alert levels.
