EDMONTON -- The wildfire detected in Yellowhead County Tuesday afternoon still burned out of control a day later, according to Alberta Wildfire.

The wildfire, nine kilometres west of Evansburg north of Highway 16 and west of Highway 22, grew from 125 hectares to an estimated 180 hectares overnight.

"People are tense," Yellowhead County Mayor Jim Eglinski said on Tuesday. "With the dry weather we're having right now, people are nervous."

Fifty residents had to leave their homes behind when an evacuation order was put in place.

"By the time I got too close to where I could see smoke half a mile from the house, they turned us back and said, 'You got to evacuate now,'" George Hyshka told CTV News Edmonton at the Evansburg Arena, where an evacuation centre was set up.

Residents with evacuation questions were encouraged to call 1-833-334-4630.

No injuries or destroyed structures had been reported.

"Our priority is protecting human lives and property," Josee St-Onge with Alberta Wildfire said.

"We're confident that we have the right resources to get this fire under control in a timely manner, but everyone in the area should remain on high alert."

At 7 p.m. Wednesday, residents in the evacuated area were allowed to return home. Officials said residents were still on evacuation alert and should be ready to leave at a moment's notice if conditions change.

Highway 16 is open to traffic in both directions but there is an advisory for reduced visibility between Highway 22 and Highway 753 due to smoke from the wildfire.

Highway 16A is closed to traffic with the exception of evacuated residents.
