Severe Weather Alerts Grip Northern and Eastern Spain

As the winter season intensifies, northern and eastern regions of Spain are bracing for severe weather conditions that have already caused significant disruptions and are expected to continue through the coming days.

Red Alerts for Heavy Snowfall

On December 9, 2024, the Spanish state weather agency, AEMET, issued red alerts for heavy snowfall in several northern regions, particularly in Asturias and Castilla y León. These alerts indicate that snow accumulation in 24 hours could reach up to 40 centimeters above 1,200 meters, posing serious risks to travel and daily life[2][4].

Affected Regions

The regions most affected by the severe weather include Asturias, Castilla y León, Cantabria, Catalonia, the Basque Country, and the Balearic Islands. In these areas, significant snowfall is expected, with accumulations that could reach five centimeters in 24 hours even in lower elevations. The Pyrenees and Cantabrian Mountains are particularly vulnerable, with snowpack instability leading to potential avalanches and landslides[1][2].

Weather Warnings

AEMET has issued a range of weather warnings, including orange alerts for snowstorms, strong winds, and rough seas. Orange alerts have been activated in elevated parts of northern Aragon, southern Asturias, northwestern Castile and León, and northeastern Navarre. Yellow alerts, indicating lesser but still significant risks, are in place for a broader area, including much of Catalonia, the Balearic Islands, and parts of the Basque Country[1][2].

Impact on Travel and Daily Life

The severe weather has resulted in hazardous travel conditions, with slippery roads and reduced visibility due to blowing snow. Several mountain passes have been closed, and authorities have implemented temporary road closures and detours. In Navarra, residents have been advised to use chains on their vehicles when driving. The Guardia Civil has conducted multiple rescue operations, including rescuing a couple trapped in their car in the province of Huesca[1][4].

Flooding and Strong Winds

In addition to snow, heavy rainfall is expected in some areas, leading to flash and areal flooding, especially in low-lying communities and urban areas with overwhelmed stormwater drainage systems. Strong winds, gusting over 100 km/h, are forecasted, which could cause property damage and power outages. The Valencia region, Catalonia, Castile and León, and the Balearic Islands are under yellow alert for wind gusts of up to 80 km/h[1][2].

Temperature Plunge

Temperatures have plummeted across the affected regions, with lows reaching as low as -9.5°C in Granada’s Sierra Nevada national park. Frosts are widespread in the northern half and southeastern quadrant of the peninsula, becoming heavy in the Pyrenees. The cold snap is part of an arctic air mass influencing the region, combined with the approach of a Mediterranean storm[2][4].

Public Precautions

Residents and travelers are advised to stay informed about the latest weather updates and follow the instructions of local authorities. The use of chains on vehicles, careful navigation of roads, and preparation for potential power outages are crucial during this period. The public is also warned about the risks of flooding, landslides, and avalanches in mountainous areas.

As the weather situation continues to evolve, it is essential for expats and locals alike to remain vigilant and take necessary precautions to ensure safety.
