Overview

• AEMET reports an Atlantic front entering from Galicia on Sunday, spreading cloud, rain and instability across the northern third as temperatures dip, with Puerto del Pico (Ávila) bottoming out at 4.5°C.
• Local forecasts in Galician towns call for fog, high humidity and persistent light showers with gusty winds, with rain probabilities near 100% and some afternoon thunder possible.
• Climatologists warn that warmer sea-surface temperatures around 27–29°C raise the energy available for intense, short-duration 'dana' downpours on the Valencian coast this autumn.
• Forecasters emphasize limits to advance warning, noting seasonal rain outlooks lose skill beyond roughly a week, while dana formation and location can often be identified within about two days.
• Authorities cite upgrades to reflectivity radars and denser real-time rain-gauge networks to speed alerts, and Argentina’s SMN has a yellow advisory for Bahía Blanca with roughly 30–50 mm of rain expected from Sunday into Monday.
