Evacuation Convoy to Rumbles Toward Fort McMurray

More than 1,500 vehicles are headed to Fort McMurray to help evacuate residents trapped in the oil fields of Alberta. Police and militiary officials are overseeing the mass exodus that also includes plans to airlift residents from the firestorm. 

All told, more than 80,000 people have evacuated Fort McMurray, though no injuries or deaths have been reported. 

Alberta's provincial government declared a state of emergency and have thrown tremendous resources at the fire, but officials caution man can only do so much.

"Let me be clear: air tankers are not going to stop this fire," said Chad Morrison, Alberta's manager of wildfire prevention. "It is going to continue to push through these dry conditions until we actually get some significant rain."

More than 1,100 firefighters, 145 helicopters, 22 air tankers and nearly 140 pieces of heavy machinery are battling the blaze that's affected 330 square miles--an area roughly the same size as Calgary.
