Welcome to our afternoon update.

South Wales Fire and Rescue Service has just provided fresh information.

The heathland fire at Llangynidr Reservoir is still burning and owing to windy conditions and the nature of the terrain, it has expanded, generating substantial smoke across the region.

Following an assessment of the situation, weather patterns, and resource requirements, an aviation-based firefighting unit is now assisting ground crews.

South Wales Fire and Rescue Service personnel are anticipated to stay at the location for several days, with their approach under constant review as circumstances develop.

Members of the public are being reminded to:

Refrain from operating drones in the vicinity as these can disrupt emergency response activities

Seal doors and windows if affected by smoke and seek appropriate medical assistance if required

Remain away from the area to permit emergency responders to function safely
