Spanish authorities have declared the highest wildfire alert across the Aragon region this weekend as firefighters continue battling a major blaze that has scorched a 4,400-hectare perimeter.

The wildfire, centred around Tamarite de Litera in the province of Huesca, remains active, although officials say it has become less intense than on Thursday, with isolated hotspots replacing the continuous fire front seen earlier.

Regional emergency chief Roberto Bermudez de Castro urged the public to exercise ‘extreme caution’ as soaring temperatures, strong southerly winds and very low humidity are expected to create dangerous fire conditions over the coming days.

Fire crews are concentrating their efforts on the northern flank of the blaze, where containment lines are still being strengthened.

The southern flank is said to be more stable but continues to be monitored closely.

Authorities stressed that the 4,400-hectare figure refers to the fire’s perimeter and does not mean the entire area has burned.

Most of the affected land is agricultural, while less than 15% is forest.

Residents in the town of Fonz have now been allowed to leave confinement after smoke levels dropped significantly.

However, officials warned restrictions could be reintroduced if conditions deteriorate.

Nearby Azanuy remains under close surveillance due to its proximity to the fire, although authorities say there is currently no immediate danger to residents.

Aerial reconnaissance flights are continuing over both Azanuy and Calasanz to monitor the blaze’s progress.

The Aragón government is also preparing to allow escorted access to evacuated villages, with Guardia Civil convoys expected to accompany residents so they can collect medication, essential belongings and care for animals once it is safe to do so.

A total of 29 people, including five children, remain evacuated. Regional authorities said they are all safe and are being supported by social services while firefighters continue working to bring the wildfire under control.
