AEMET Warns of DANA Bringing Heavy Rain, Sharp Temperature Drop This Weekend
Spain faces a sudden weather shift as a high-altitude depression threatens intense storms and a return to seasonal norms after an unusually warm October spell.

KEY POINTS
- AEMET confirms a DANA will bring heavy rain and a sharp temperature drop to Spain this weekend.
- Temperatures have been running 5-10°C above normal for October, with highs near 34°C in the southwest.
- The change begins Friday with rain in the northwest; Saturday brings widespread storms across the peninsula.
- Highest rainfall risk: Valencian Community, Catalonia, Balearics, Murcia, eastern Andalusia — locally over 100 l/m².
- Significant uncertainty remains on the DANA's exact track and final rainfall distribution.
Spain's meteorological agency AEMET has confirmed a sharp weather change arriving this weekend, ending a period of temperatures 5 to 10 degrees above average for October. A high-altitude trough is expected to isolate into a DANA (cut-off low) by Saturday, bringing widespread heavy rain and a significant temperature drop.
The transition begins Friday, October 16, when a front brings cloud and rain to northwestern Galicia and the Cantabrian region while the rest of the country remains stable and warm. Cities like Seville and Badajoz could still reach 33-34°C before the change takes hold.
“The episode will gain intensity during the weekend, although its exact evolution may still experience changes.”
Saturday marks the main event as cold polar air funnels south behind high pressure near the British Isles. Rain will reach nearly the entire peninsula, with persistent downpours expected on the Cantabrian slope, the south, and the eastern half of the country.
The heaviest accumulations are forecast for the Valencian Community, Catalonia, the Balearic Islands, Murcia, and eastern Andalusia. Localized totals may exceed 100 liters per square meter, accompanied by hail and strong wind gusts.
AEMET stresses significant uncertainty remains regarding the DANA's exact position and resulting rainfall distribution. The episode is expected to intensify through the weekend, though the precise evolution may still shift.
