An army of firefighters struggled Tuesday to contain wildfires and burning homes in the drought-stricken western states, raging as much as the second heatwave of the year in warm, dry and windy conditions.
Almost 60 wildfires raged between Alaska and Wyoming, according to the National Interagency Fire Center.
Arizona, Idaho and Montana were responsible for more than half of major active fires.
The Bootleg Fire, which has devastated over 818 square kilometers – more than twice the size of Portland – has threatens some 2.000 homes, the state fire department said.
The week-old bootleg blaze had covered as much as 316 square miles by Tuesday morning, threatening about 2.000 homes, and destroyed more than 20 other and smaller buildings.
The fire had sharply disrupted operations of three transmission lines in the Fremont-Winema National Forest near the county city of Sprague River that can power up to 5.500 megawatts of California.
The fire has been fueling by winds, hot weather and a lot of moisture.
The fire has severely disrupted operations of three transmission lines that supply California about 5.500 megawatts of electricity, and the state’s gridlocked electric grid operator repeatedly called for voluntary electricity savings in the hours after the blaze was launched.
