Emergency services are continuing to tackle a scrubland fire in the Pentrefelin area, near Holyhead.
North Wales Fire and Rescue Service (NWFRS) says around 1,000 square metres of land are affected.
Around 30 firefighters are at the scene, along with seven fire engines, a wildfire unit and specialist officers as efforts continue to contain the fire and prevent further spread, while continuing to monitor weather conditions.
Local residents are being told to keep their windows and doors closed because of smoke but the Fire Service says there is no need to evacuate the area at the moment.
A NWFRS spokesperson said: "Firefighters remain on scene, continue to monitor the situation closely, and are maintaining regular contact with those living nearby. Should circumstances change, appropriate support and assistance will be provided."
They added: "We continue to ask members of the public to avoid affected areas, allowing emergency crews to work safely and ensuring access for operational vehicles."
Earlier, the Fire Service advised residents to ventilate their properties once the smoke has dispersed by opening their windows and doors.

Earlier, Ynys Môn MP,Llinos Medi said residents around Clos y Goleudy, Waen Fawr and Old Mill Cottage were being advised to keep their windows closed, adding that anyone worried about their safety should call 999 immediately.
Elsewhere, crews are also dealing with an ongoing wildfire in the Rhinogydd mountains near Cwm Bychan lake, close to Harlech with local roads and footpaths closed and the public urged to stay away from the area.
NWFRS said helicopter support from Natural Resources Wales had been approved to tackle the Rhinogydd fire, but it was not currently available due to to demand from other wildfires elsewhere in the UK.
On Thursday, crews also returned to the Braichmelyn forest near Bethesda where a further fire was brought under control.
It's believed an earlier fire in the area may have been started by people using makeshift fire pits.

Andrew McLaren from the Joint Emergency Services Group said: "The recent incidents we have attended across North Wales highlight just how quickly fires can spread in the current conditions."
"As people enjoy the summer holidays, we are asking everyone to act responsibly and help us protect our countryside."
"Please do not light open fires, avoid using disposable barbecues in rural areas, and always dispose of cigarettes and smoking materials safely. Small actions can make a big difference and help prevent fires that can have a devastating impact on our communities, wildlife and environment."
