Firefighting efforts are continuing on the Slieve Bloom Mountains for a fifth day today as the heatwave is set to continue through the coming week.
Offaly and Laois Fire Services now have the fire contained to a small area. Together with Coillte they are working to extinguish it.
The fire broke out on the Offaly side of the midland mountain range on Wednesday.
Wind and dry conditions saw it spread across the border to Laois by Wednesday night.
