Hot, Dry Conditions Drive Wildfires in Western US and Canada

Firefighters in the western United States and Canada are battling numerous wildfires as hot, dry weather worsens drought conditions. 

A wildfire burning in southern Oregon, near the California border, expanded to more than 600 square kilometers, prompting evacuations and disrupting electrical transmission lines that deliver electricity to California.  Firefighters are not likely to get much relief in the coming days with conditions forecast to be dry and windy, with temperatures well above average. Authorities said Sunday they are shifting more crews to working overnight when it is easier to battle the fires and build containment lines.  California is dealing with its largest wildfire of the year, burning just north of Lake Tahoe. The Beckwourth Complex Fire grew to 348 square kilometers in size, while firefighters managed to get it 20% contained.
