Severe Weather Alerts Issued for Northern Spain, Including Cantabria

As the winter season intensifies, northern Spain, particularly the region of Cantabria, is bracing for severe weather conditions that are expected to impact the area significantly. Starting from Thursday, December 12, 2024, Cantabria and several other northern regions will be under various weather alerts due to an arctic air mass and a Mediterranean storm system.

Heavy Snowfall and Low Temperatures

The State Meteorological Agency (AEMET) has issued red alerts for heavy snowfall in regions such as Asturias and Castile and León. In these areas, snow accumulation is expected to reach up to 40 centimeters above 1,200 meters within a 24-hour period. Cantabria, although not under a red alert, will still experience significant snowfall, with accumulations that could reach five centimeters in 24 hours. The low temperatures will be particularly harsh, with frosts expected to affect most of the interior of the northern half of the peninsula, becoming heavy in the Pyrenees and Cantabrian Mountains[1][2].

Strong Winds and Rough Seas

In addition to the snow, strong winds are forecasted to hit the region. Wind gusts could exceed 100 km/h, especially in the northwest quadrant, the Cantabrian Sea, the Pyrenees, and the Iberian system. These winds may locally become 'hurricane-like' in intensity, posing significant risks to property and infrastructure. The Balearic Islands, northern and eastern coastlines of mainland Spain, and parts of Cantabria and Catalonia are under orange alerts for rough seas, with waves expected to reach up to six meters high[2][3].

Rainfall and Flooding

Heavy rainfall is also anticipated, particularly along the Cantabrian coast, the Pyrenees, and the north of the Iberian system. This could lead to flash and areal flooding in low-lying communities near watercourses and urban areas with overwhelmed stormwater drainage systems. The provinces of Asturias, Cantabria, Burgos, Barcelona, and the Balearic Islands are on yellow alert for downpours that may accumulate up to 40mm in twelve hours[1][2].

Travel Disruptions and Safety Precautions

The adverse weather conditions are likely to cause hazardous travel conditions, especially in elevated areas due to slippery roads and reduced visibility from blowing snow. Authorities may implement temporary road closures or detours in areas heavily affected by snow. Mountain passes and tunnels could be closed as a precautionary measure during periods of intense snowfall. Flooding in urban areas may result in significant traffic congestion, and power outages are possible due to strong winds and heavy snowfall[2].

Regional Impact

The weather alerts are not limited to Cantabria but extend to several other regions, including Asturias, Castile and León, Aragon, Catalonia, Navarre, the Basque Country, and the Balearic Islands. Each of these regions will face varying levels of snowfall, rainfall, strong winds, and rough seas, necessitating careful planning and precautions from residents and travelers alike.

As the weather situation continues to evolve, expats and locals in northern Spain are advised to stay updated with the latest forecasts and follow the instructions of local authorities to ensure their safety during this period of severe weather.
