Winnemucca, Nevada ? High wind hampered fire crews again Sunday as they fought a wildfire that had dashed across nearly 300 square miles of remote rangeland in northern Nevada.

The brush fire 50 miles northeast of Winnemucca had exploded from less than 30 square miles to 292 square miles since Thursday, making it one of the nation’s biggest wildfires of the season, fire information officer Susan Marzec said.

No buildings had been damaged, but the blaze posed a potential risk to the tiny towns of Midas and Tuscarora as well as scattered ranches. Flames were within three miles of Midas and 11 miles of Tuscarora.

“The fire is continuing to make its move because of gusty winds and dryness,” Marzec said. “Every time we make headway we’re back where we started.”

The fire was just 5 percent contained and no estimate was available on when it would be fully contained.
