A massive wildfire continued to spread Friday in central Washington state as hot dry weather fueled a rash of new blazes, UPI reported. The Mills Canyon fire near Entiat charred 28 square miles Thursday evening and put around 200 buildings at risk. The fire, first reported Tuesday, also threatened orchards and herds of sheep. By Friday morning, the fire was reported to be 19 percent contained. Some evacuation orders were lifted. Four smaller fires burned in the region. Forecasters predicted temperatures of 100 degrees and more in the area over the weekend. Matt Fugazzi, of the National Weather Service in Spokane, Wash., said hot dry weather turns grass, shrubs and trees into "organic gasoline, just waiting for any spark or trigger." Two hotshot crews were transferred from the Mills Canyon fire after the 25 Mile Creek fire was reported nearby Thursday. By Friday morning, the fire had spread across 400 acres, but officials said a fire line surrounded the blaze and they believed it would be contained during the day.
