A fresh DANA and an incoming cold front will trigger heavy, thundery showers across the Catalan coast and north-east interior from Sunday, with temperatures falling sharply. Civil protection has activated the INUNCAT flood plan amid warnings of intense bursts of rain, hail and strong winds. Meteocat expects storms to start along the Barcelona and Girona pre-coast, then spread inland into Central Catalonia, Ponent and the Pyrenees through afternoon and evening, creating flash-flood potential on steep terrain. AEMET confirms the recent heatwave was the most intense on record, leaving unstable, moisture-rich air for storms to feed on.
A fresh DANA - an upper-level low that often unleashes lively downpours - is lining up to break Spain's record heat and drench Catalonia from Sunday, with showers spreading inland and a sharp dip in temperatures. Civil protection chiefs have already activated the INUNCAT flood plan, warning of intense bursts of rain, hail and gusty winds. Storm timeline: when the rain arrives and where it hits first
Flash-flood potential. In the eastern Pyrenees - notably Ripollès (Girona), Berguedà (Barcelona) and La Garrotxa (Girona) - downpours could top 20 litres per square metre in just 30 minutes, the classic recipe for sudden flooding on steep terrain. National picture. AEMET says a cold front slips in from the northwest while the DANA spins up over the southwest, a one-two that promotes heavy, thundery showers on the Catalan coast and the north-east interior, with a few storms bubbling up over south-eastern mountains too.
Morning set-up. Before the break in the weather, the southern coastal strip has struggled to cool - lows of 24-25°C at 6am were logged - leaving juicy air in place for storms to feed on once the upper disturbance arrives. Hottest on record. Spain's latest heatwave was the most intense ever recorded, AEMET confirms, edging out July 2022. On preliminary figures, the "heatwave anomaly" - how far maximums overshoot the threshold - hit +4.6°C.
