Severe Weather Alert: Northern and Eastern Spain Braces for Adverse Conditions

As the first week of December unfolds, northern and eastern Spain are gearing up for a period of severe weather, prompting significant alerts and warnings from the State Meteorological Agency (AEMET).

Weather Warnings and Alerts

From December 7 to 10, a powerful storm system is expected to impact various regions, including the northern parts of the peninsula and the Balearic Islands. Here are the key alerts issued by AEMET:

• Orange Snowstorm Warnings: Elevated areas of northern Aragon, southern Asturias, northwestern Castile and Leon, and northeastern Navarre are under orange alerts, indicating a high risk of heavy snowfall. Snow accumulations of over 40 cm (16 inches) are predicted in the Cantabrian and Pyrenees mountain ranges on December 8-9[1].
• Orange Strong Wind Warnings: Parts of southern Catalonia, northern Valencia, and Mallorca in the Balearic Islands are warned of strong winds, with gusts potentially exceeding 100 kph (62 mph)[1].
• Orange Rough Sea Warnings: The Balearic Islands, much of the northern coastline, and parts of the northeastern coastline are under orange alerts for rough seas[1].
• Yellow Snowstorm, Strong Wind, and Rough Sea Warnings: Various other regions, including La Rioja, Navarre, and parts of Catalonia, Castile and Leon, and the Basque Country, are under yellow alerts, indicating a lower but still significant risk of adverse weather conditions[1].

Impact on Travel and Daily Life

The severe weather is expected to cause hazardous travel conditions, particularly in elevated areas where heavy snowfall and strong winds will lead to slippery roads and reduced visibility. Mountain passes and tunnels may be closed as a precautionary measure during periods of intense snowfall.

Flooding is also a concern in areas experiencing heavy rainfall, with low-lying communities near watercourses and urban areas with overwhelmed stormwater drainage systems being particularly vulnerable. Flash flooding and landslides cannot be ruled out, especially in areas of elevated terrain. Additionally, power outages are possible due to strong winds and heavy snowfall[1].

Regional Specifics

• Cantabria: This region is expected to be one of the hardest hit, with heavy rain forecasted and a high risk of snowfall in elevated areas. The rain will be heaviest in Cantabria, although it may spread to other southern regions in a weaker form[2].
• Balearic Islands: The islands will experience strong winds, rough seas, and potential power outages. Yellow and orange alerts for strong winds and rough seas have been issued for these areas[1].
• Catalonia and Valencia: These regions will face strong winds and rough seas, with orange alerts in place for certain areas. Flooding and property damage are potential risks due to the adverse weather conditions[1].

Preparations and Advisories

Residents and visitors are advised to stay updated with the latest weather forecasts and warnings. AEMET may update and extend the coverage of weather alerts over the coming days as the situation evolves.

For those planning to travel, it is crucial to check the latest road conditions and weather updates before embarking on any journey. Authorities may implement temporary road closures or detours in areas affected by heavy snow and strong winds.

As Spain transitions into the winter season, this severe weather episode marks a significant shift from the unseasonably mild and balmy conditions experienced just a week ago. Expats and locals alike should be prepared for the cold snap and potential disruptions it may bring.
