Alberta wildfire prompts evacuation of 12 homes

A change in wind direction prompted the evacuation of 12 homes on Tuesday due to an encroaching wildfire about 250 kilometres northeast of Edmonton.

RCMP in Bonnyville, Alta., said the 800-hectare fire was moving northwest, which put residents "in a degree of danger."

Fire information officer Geoff Driscoll said that one house was threatened by the fire on Tuesday night and crews were trying to get a fire guard built to contain the blaze, which grew by about 150 hectares earlier in the day.

A spokeswoman from the Bonnyville Municipal District said firefighters were able to stop the advancing fire at a location about six kilometres north of Moose Lake, south of Township Road 622. Driscoll said diminishing winds helped the effort.

"The fire is still considered out of control, but they were able to slow down the fire compared to what it was this afternoon," he said.

A second fire was also reported south of Muriel Lake. Crews created a fire guard to contain the blaze.

Bonnyville also declared a local state of emergency on Tuesday, which allows officials to call in the RCMP to secure roads and homes, if necessary.

"We want to emphasize that the evacuation is only for residents within Township 62-7," said Diane Jenkinson, a public information officer with the Bonnyville district. "No other areas are affected by the evacuation."

The fire is one of two that remained out of control in northern Alberta on Tuesday. A fire 15 kilometres northwest of Grassland is 1,000 hectares in size. Fire crews will spend the night trying to complete a fire guard around the perimeter, Driscoll said.

A third fire near Lodgepole is fully contained and no longer out of control.

The province issued a fire ban for all forested provincial lands Monday as the wind and warm, dry weather continue to make the job difficult for firefighters.

The ban covers outdoor fires, the use of portable campfires and fireworks from Waterton National Park north along the foothills to beyond Manning and northeast to Fort McMurray.
