An 8,000-acre wildfire forced hundreds of people in the town of Winnemucca to leave their homes, one of more than a dozen blazes that charred a combined 55 square miles in northern Nevada, the Associated Press reported. The blaze was among a series that dotted the West on Saturday as a heat wave made parched terrain even drier, forcing authorities to evacuate homes and close highways and wilderness areas. A 100-mile stretch of Interstate 15 in central Utah was closed when a 160,000-acre wildfire jumped the highway, and other fires burned in California, Colorado, Arizona, Idaho, Oregon and Washington. The fire near Winnemucca, about 170 miles east of Reno, threatened up to eight blocks of homes and an electrical substation, said U.S. Bureau of Land Management spokesman Jamie Thompson.
