Authorities are concerned that the massive wildfire in Fort McMurray in western Canada could double in size by the end of Saturday. Over 88,000 people have already evacuated the area due to the blaze. Residents were ordered to evacuate on Tuesday once the fire reached city limits. Evacuees have been led in different directions by the Royal Canadian Mounted Police and some evacuated the area by plane. There are a total of 49 wildfires raging in Alberta, with seven considered to be out of control.
