Brazeau County delivered 200 evacuation notices to residents in the Lindale area.
It's the second forest fire the county has had to battle. Residents in Lodgepole, 55 kilometres southwest of Lindale, returned to their homes a week ago after a fire threatened their community.
No homes in the Lindale area have been destroyed, and just one outbuilding has burned, said county spokeswoman Wanda Compton.
Another 200 people in the nearby Birchwood area were put on one-hour evacuation alert.
Municipal crews were getting help with the 17-hectare blaze supported by provincial government water bombers, helicopters, bulldozers and ground crews.
A reception centre has been set up in Drayton Valley to help evacuees.
The wildfire danger in many parts of Alberta is listed as high to extreme due to bone-dry conditions, coupled with strong, gusty winds.
The fire was spotted around 3 p.m., and fire crews got on it fast, Compton said.
"They are making good headway, but weather conditions are playing havoc on the fire."
Late Wednesday, the fire jumped Township Road 500. Compton said they asked the province for help, and three eight-man crews were added to the other 15 local firefighters on the ground.
Compton said the Lindale fire is "looking a lot better than we had in Lodgepole."
