The Bombers de la Generalitat (Catalan Firefighters) worked intensely throughout Sunday to contain the blaze, utilizing aerial resources such as three helicopters and a water bomber, due to the terrain's challenging topography. Specialized GRAF and EPAF units, helitransported, executed defense lines and technical fire maneuvers to keep the fire within established containment axes.
In the afternoon, the fire saw a resurgence with the formation of a fire plume, driven by ascending wind currents. Aerial resources carried out water drops in the lower areas to prevent the fire's spread. Concurrently, the GRAF and EPAF units worked in the higher zones to break continuity paths and prevent the fire from reaching the Vall de Boí.
Firefighters warn that the fire could remain active for several days. The boundaries they are trying to protect are, to the north, the Escobedieso ravine; to the south, the crest of the Munyidor ravine; to the west, the Noguera Ribagorçana river, to prevent it from crossing into Catalonia; and to the east, a high pasture area near the Vall de Boí.
The terrain's steepness and lack of access make ground operations difficult, necessitating reliance primarily on aerial means for fire control. During the night, perimeter checks and surveillance of the area were conducted using drones.
