The BC Wildfire Service says the Coal Creek Fire 12 kilometres east of Fernie is displaying extreme behaviour, making it unsafe for crews to respond.
Crews will continue to assess the situation, as the Coal Creek blaze was last estimated at 548 hectares.
While the wildfire has spread going into the weekend, the BC Wildfire Service says there is currently no threat to nearby communities.
Meanwhile, the McDermid Creek Fire near Elko has grown to 290 hectares in size.
Heavy equipment opened up access roads near the fire in earlier days.
The lightning caused fire remains highly visible from Highway 3, the community of Galloway, Fernie and the surrounding area.
The BC Wildfire Service says while its quite visible, its burning in the backcountry and not threatening any communities at this time.
