The raging wildfire that has forced the evacuation of Fort McMurray, Alta., and engulfed parts of the community is the kind of blaze that firefighters dread, but could become more common, according to experts.
Alternatively described by officials as "catastrophic," a "multi-headed monster" and a "dirty, nasty" fire, the blaze is at least 80,000 hectares in area and has destroyed more than 1,600 structures. It could threaten the entire town, the fire chief told reporters.
The wildfire became so intense Tuesday that the heat limited air operations over the affected areas. More than 150 firefighters are battling it on multiple fronts, with hundreds more from other provinces scheduled to arrive in the coming days.
