Wildfire threatening Fort McMurray grows in size, crews face hot, dry day

FORT MCMURRAY, Alta. — The wildfire threatening Fort McMurray in northern Alberta has grown in size as crews work to shield part of the city from the flames.

Crews and bulldozers kept the fire from spreading overnight east toward a camping area and two neighbourhoods.

Fire officials say the challenge today will be rising temperatures and low humidity that could cause the flames to spread north toward the city.

Darby Allen, fire chief of the Regional Municipality of Wood Buffalo, says just because people can't see flames doesn't mean they should let their guard down.

He says it is safe for people in the community to go about their normal lives, but they should have a plan in case the fire gets worse.

The wildfire danger for forested areas in much of Alberta and Saskatchewan ranges from high to extreme.
