A wildfire moves towards the town of Anzac from Fort McMurray, Alberta., on Wednesday May 4, 2016. Alberta declared a state of emergency Wednesday as crews frantically held back wind-whipped wildfires. Unseasonably hot temperatures combined with dry conditions have transformed the boreal forest in much of Alberta into a tinder box. (Photo by Jason Franson/The Canadian Press via AP Photo)
