Northern regions of Spain have been hit with serious traffic disruptions due to heavy snowfall. As a result of the severe weather, movement is difficult on 19 highway sections across Asturias, Cantabria, Burgos, León, Huesca, and Navarra. Authorities warn that conditions may worsen and advise drivers to prepare in advance or postpone their trips altogether.

In Navarra, the NA-137 near Isaba is completely closed. Chains are mandatory on twelve other routes. In Asturias, this applies to five mountain passes: Puerto de San Isidro (AS-112), Tarna (AS-117), Puerto de Leitariegos (AS-213), Puerto de Somiedo (AS-227), and Puerto de Ventana (AS-229). In Cantabria, restrictions are in force on four roads: Saja (CA-280), Pandillo (CA-631), San Pedro del Romeral (CA-633), and Valdicio (CA-643).
