Fire crews are battling a blaze which took hold on a hillside near the border village of Killea on Friday afternoon.
The blaze spread rapidly through the dry gorse, and large plumes of smoke are visible from the village.
Donegal County Council has relayed a wildfire warning issued by Department of Agriculture, Food and the Marine as the dry weather continues. The notice is in effect until midday on May 12.
It reads: "Donegal County Council wishes to appeal to landowners and members of the public to exercise caution and to take all necessary measures to prevent the occurrence of wildfires.
"Landowners and members of the public are urged to be vigilant and to report any uncontrolled or unattended fires immediately to the fire service by dialling 999 or 112.
"House holders or building owners in areas susceptible to wildfire are advised to remove or cut back any vegetation in the immediate vicinity of their house, building or oil tank to prevent wildfires damaging or destroying their property. Cleared areas should be maintained free of vegetation and combustible material.
"Members of the public and visitors to recreational areas should cooperate with all requests regarding fire safety, obey all relevant bye-laws and be considerate in parking vehicles so as not to impede access by emergency vehicles."
Where fire outbreaks occur at or near recreational areas the following actions should be taken by visitors in the interests of safety:
1. Do not light fires in and around forests or open land.
2. Do not attempt to intervene or fight fires under any circumstances.
3. Gather all family/group members and move to a safe fuel-free location such as a car park, upwind of the fire.
4. Telephone Fire and Rescue Services via 112 and report the fire and its location.
5. Evacuate if instructed to do so, and cooperate with all Emergency Service Instructions.
Donegal County Council would also like to remind landowners and members of the public that under the Wildlife Acts, 1976 and 2000 it is an offence to cut, grub, burn or otherwise destroy any vegetation growing on any land not then cultivated between March 1 and August 31 in any year.
Members of the public are also reminded that the burning of domestic, industrial, agricultural and construction waste is an offence under the Waste Management Act, 1996.
