On December 15, 2024, the Pyrenees mountains experienced an intense snowstorm that transformed the landscape, affecting both sides of the mountain range.
In Spain, the Ebro Valley was shrouded in morning fog and coated with widespread frost, particularly in low-lying areas. These conditions created challenges for drivers, prompting authorities to issue safety advisories due to reduced visibility and slippery surfaces.
In France, the snowstorm’s impact was heightened by avalanche warnings across several departments in the western Pyrenees. Authorities emphasized the need for caution, as unstable snowpack conditions posed risks for outdoor activities and nearby communities.
By December 16, as the skies cleared, the Copernicus Sentinel-3 satellite captured a vivid image of the Pyrenees, showcasing the expansive snow cover from space.
This open data from Copernicus Sentinel satellites plays a critical role in monitoring environmental changes in mountainous regions. By providing detailed information on snow cover, frost, and other conditions, these observations support evidence-based decision-making for safety and resource management in affected communities.
