A raging wildfire in Alberta has now spread to 210,000 acres following dry and blustery conditions, coupled with high temperatures and low humidity.
Bill Patzert, a climatologist at NASA, told CBS: "The flames are moving so fast that they are nearly impossible to fight. In a way, it's a perfect storm."
The Alberta government have confirmed 1,100 firefighters, 145 helicopters and 22 air tankers were currently tackling 49 wildfires across the western and southern parts of the state.
According to local media, over the past 24 hours a further 25,000 people have been evacuated including 8,000 by air.
