Sabadell sits on Spain’s Mediterranean coast (or nearby islands), where hot, dry summers give way to the year’s most dangerous weather in autumn, when warm sea-surface temperatures fuel intense, slow-moving storms known locally as gota fria or DANA (an isolated depression at high altitude).
Near Terrassa in Catalonia’s Valles region, the city faces similar flash-flood exposure from the area’s small, steep streams. These autumn storms can drop several months’ worth of rain in a single day, as seen repeatedly across eastern and southern Spain in recent decades, which is why radar imagery is central to how Spain’s AEMET meteorological agency issues flash-flood warnings.
