Spanish meteorological authorities have declared a red alert for parts of Northern Spain, with heavy snowfall expected over the weekend. The Catalan region of La Vall d’Aran is predicted to see significant snow accumulation. Strong winds are also forecast, prompting officials to urge travellers to stay updated on weather conditions.
What a red alert means
A red alert is the highest level of weather warning issued by AEMET. It indicates extreme risk to life and property due to severe weather conditions. The alert system follows a colour-coded scale: green for no risk, yellow for low risk, orange for significant risk, and red for extreme risk. Red alerts are reserved for situations where extraordinary weather events, such as heavy snowfall, storms, or flooding, are likely to cause widespread disruption and potentially endanger lives. Residents and travellers in affected areas are advised to take immediate precautions and follow guidance from local authorities.
Unusual snowfall conditions in the Pyrenees
While snowfall in the Pyrenees during winter is typical, the conditions forecast this weekend are extreme. A cold air mass is causing a sharp temperature drop, accompanied by intense winds and heavy snow across Catalonia and Aragón. The Spanish Meteorological Agency (AEMET) reports that up to 40 centimetres of snow could fall in La Vall d’Aran within 24 hours. As a result, a red alert covers the Pyrenees in Lleida, Huesca, and Navarra.
Timeline of weather alerts
AEMET has announced that an orange alert will take effect in the Pyrenees on Saturday, December 7, from 3.00 pm to 5.00 pm. This will escalate to a red alert at 6.00 pm, lasting through Sunday, December 8. Although snowfall is common in these regions, the projected accumulation is unusually high, posing significant risks.
Heavy traffic anticipated during long holiday weekend
The weather warning coincides with a long holiday weekend in Spain. With national holidays on December 6 and December 8, many Spaniards are taking advantage of the extended break, leading to increased travel. Roads are expected to be particularly busy as people journey for vacations or family visits.
Travel advice: Snow chains and caution recommended
AEMET advises travellers to remain cautious and monitor local weather updates. Drivers heading to snowy areas should carry snow chains if their vehicles lack winter tyres. The snowline in the Pyrenees could drop to 800 metres, and strong winds may create snowdrifts, causing hazardous conditions. Meteocat, Catalonia’s meteorological service, has also warned of potential “torb”—snowstorms driven by high winds—in higher altitudes.
Wind warnings for coastal and island regions
In addition to the snow, strong winds are expected to impact the north-eastern coast and the Balearic Islands. Warnings have been issued for Lleida, Tarragona, and Mallorca. High-altitude areas in Lleida and Tarragona could experience dangerous conditions, while strong winds are also predicted for northern coastal regions, though no alerts have been issued there.
Stay prepared and informed
Authorities are urging the public to prepare for disruptions caused by extreme weather. Whether travelling by road or remaining in affected regions, staying informed and cautious will be crucial during this period of severe snowfall and high winds.
