Large wildfires have affected the Dyffryn Nantlle area of Gwynedd in the last 24 hours. Firefighters and a helicopter have been brought in to help put out the blaze in Mynydd Tal y Mignedd and Mynydd Mawr, and smoke can be seen from as far away as Anglesey.
A blaze began on Wednesday afternoon near Y Fron village, which covered an area of 100,000 sqm before four appliances and a specialist wildfire unit were able to tackle it. A helicopter from south Wales has also travelled to the area to help by dropping water on the fire.
The North Wales Fire and Rescue Service is urging residents in the villages of Y Fron, Rhosgadfan and Rhostryfan near Caernarfon to keep windows and doors closed. A spokesperson said: "We’re monitoring the fire but there remains considerable smoke in these areas".
