On December 12, 2024, the Spanish Meteorological Agency (AEMET) issued alerts for ten autonomous communities due to extreme cold, heavy rain, and snowfall. The forecast indicates temperatures dropping to -6 degrees Celsius in several regions, with orange alerts in Andalusia and Catalonia for rainfall accumulation reaching up to 40 liters per square meter within an hour.
Communities under yellow alert include Huesca, Cordillera and Picos de Europa, Liébana, and various regions in Castilla y León and Navarra, with warnings for low temperatures and snowfall. In Barcelona's coastal area, significant rainfall is expected later in the day, accompanied by storms and hail.
In Andalusia, particularly in Málaga, rainfall of 30 liters per square meter is anticipated in areas such as Axarquía and Guadalhorce. Snow accumulation is projected to reach 5 centimeters above 1,300 meters in the pre-Pyrenees of Barcelona and Girona.
Frost conditions are likely to impact much of northern Spain and the southeastern quadrant, with particularly severe frosts expected in the Pyrenees. The coldest provincial capitals include León, Salamanca, and Soria with temperatures as low as -3 degrees Celsius.
As the day progresses, temperatures are forecasted to rise slightly in the north and Mediterranean regions, with Bilbao and Santander approaching 15 degrees Celsius and Alicante reaching up to 17 degrees Celsius.
Looking ahead to December 13, most areas will experience sunny weather, although a low-pressure system may bring light rain to Extremadura and western Andalusia. Nighttime frosts will persist in the interior, while daytime temperatures in the Mediterranean and Balearic regions could reach 18 degrees Celsius.
